Question 1

What is font conversion?

Accepted Answer

Font conversion is the process of transforming a font file from one format to another (e.g., TTF to WOFF2) while preserving all glyph data, metrics, and features. Conversion enables fonts to work across different platforms and optimizes them for specific use cases, such as web delivery.

Question 2

Is font conversion free on this site?

Accepted Answer

Yes, our font converter is 100% free with no limits, no signup required, no watermarks, and no restrictions on commercial use.

Question 3

Do I need to create an account to convert fonts?

Accepted Answer

No account needed. Upload your font, select output format, and download - completely anonymous and instant.

Question 4

How many fonts can I convert at once?

Accepted Answer

You can upload and convert up to 50mb, no limits on the font files, using our batch converter.

Question 5

Are my fonts safe when I use this tool?

Accepted Answer

Absolutely. All processing happens in server RAM only, so your font files are never saved to disk or stored permanently. Files are processed and immediately deleted.

Question 6

What font formats do you support?

Accepted Answer

Input formats: TTF, OTF, WOFF, WOFF2, EOT, SVG, DFONT, PFB (8 formats). Output formats: TTF, OTF, WOFF, WOFF2, EOT, SVG, DFONT, PFB (8 formats).

Question 7

Can I convert multiple different formats in one batch?

Accepted Answer

Yes, you can mix input formats in a single batch (e.g., 5 TTF + 3 OTF + 2 WOFF files), and they'll all convert to your selected output format.

Question 8

How long does font conversion take?

Accepted Answer

Conversion is near-instant, typically completing in 1-3 seconds per font file. Batch conversions process all files simultaneously. The maximum time taken will be 30 seconds to 1 minute for 50 MB files.

Question 9

Do you store or keep my font files?

Accepted Answer

No. Since processing happens in our RAM, we never store, log, or have any access to your font files. This also means there will be no cookies to save your conversions. If you reload, you need to convert them again.

Question 10

Can I use this for commercial projects?

Accepted Answer

Yes, our tool is free for commercial use. However, you must ensure you have proper licensing rights for the fonts you're converting for commercial use.

Question 11

What happens to my converted fonts after I close the browser?

Accepted Answer

Converted fonts are downloaded to your device. The original files are processed in server RAM only and immediately deleted - never stored permanently. Once you download the converted fonts, they're saved on your device.

Question 12

Can I convert fonts on mobile devices?

Accepted Answer

Yes, our tool works on all modern mobile browsers (iOS Safari, Android Chrome, Samsung Internet, etc.).

Question 13

Is there a file size limit for font conversion?

Accepted Answer

Maximum 50 MB per font file or batch upload. Most fonts are 100KB-2MB, so this limit accommodates even large Unicode fonts.

Question 14

Do you support variable fonts?

Accepted Answer

Yes, variable fonts (OpenType 1.8) can be converted between supported formats while preserving all variation axes.

Question 15

Can I convert web fonts back to desktop formats?

Accepted Answer

Yes, WOFF/WOFF2 can be converted back to TTF/OTF for desktop use. Conversion is lossless. We support 8 formats with 56 conversion paths.

Question 16

What is WOFF2, and why should I use it?

Accepted Answer

WOFF2 (Web Open Font Format 2) uses Brotli compression to achieve 70% file size reduction vs TTF. It's the recommended format for modern web fonts - faster loading, better performance, 96% browser support.

Question 17

Does conversion reduce font quality?

Accepted Answer

No. Conversion between modern formats (TTF, OTF, WOFF, WOFF2) is 100% lossless. All glyph outlines, kerning, ligatures, and OpenType features are perfectly preserved.

Question 18

What is the difference between TTF and OTF?

Accepted Answer

TTF uses quadratic Bézier curves (simpler, faster). OTF can use either quadratic (TrueType outlines) or cubic Bézier curves (PostScript/CFF outlines - more precise for complex designs). Both are "OpenType" fonts.

Question 19

Can I convert OTF to TTF without quality loss?

Accepted Answer

OTF with PostScript outlines → TTF requires converting cubic to quadratic curves. This introduces a <1% approximation, visually imperceptible in 99% of cases.

Question 20

What is font subsetting?

Accepted Answer

Removing unused characters from fonts. English-only subsetting keeps ~100 glyphs instead of 250+, reducing file size 50-70% beyond compression. Use our universal font conversion tool and select the subsetting tool after conversion.

Question 21

What are OpenType features, and are they preserved?

Accepted Answer

Ligatures (fi, fl), contextual alternates, stylistic sets, kerning pairs, small caps - all stored in GSUB/GPOS tables. Yes, conversion preserves all OpenType features.

Question 22

What is Brotli compression?

Accepted Answer

Google's compression algorithm is designed for web resources. WOFF2 uses Brotli, achieving 30% better compression than WOFF's gzip while maintaining identical quality.

Question 23

Can I extract fonts from WOFF/WOFF2 files?

Accepted Answer

Yes. WOFF and WOFF2 are compressed containers. Convert back to TTF/OTF to extract the original TrueType/PostScript outlines.

Question 24

What is the difference between WOFF and WOFF2?

Accepted Answer

WOFF uses gzip compression (~40% reduction), WOFF2 uses Brotli (~70% reduction). WOFF2 is 30% smaller, supported by 96% of browsers. WOFF needed only for IE9-11 fallback.

Question 25

Do converted fonts work with variable font axes?

Accepted Answer

Yes. Variable fonts (weight, width, slant, optical size axes) are preserved during conversion. All variation data remains intact.

Question 26

What is EOT, and why is it obsolete?

Accepted Answer

Embedded OpenType - Microsoft's proprietary format for IE6-11. Obsolete because IE11 ended support in 2022, and WOFF/WOFF2 offer better compression without DRM.

Question 27

Can I convert color fonts (emoji fonts)?

Accepted Answer

Partial support. Basic conversion works, but color tables (COLR, CBDT, SVG) may not be fully preserved in all format combinations. Test output thoroughly, and contact us if needed.

Question 28

What is font hinting, and is it preserved?

Accepted Answer

Hinting = bytecode instructions for grid-fitting at small pixel sizes. Yes, preserved during conversion, but removing hinting can reduce file size 20-30% (use our hinting removal tool).

Question 29

What are glyph outlines?

Accepted Answer

Mathematical descriptions of letterforms using Bézier curves. TTF uses quadratic, PostScript uses cubic. Outlines enable fonts to scale infinitely without quality loss.

Question 30

Can I convert fonts with custom ligatures?

Accepted Answer

Yes. All ligature data in the GSUB table is preserved. Ligatures will work identically in converted fonts.

Question 31

What is the difference between web fonts and desktop fonts?

Accepted Answer

Web fonts (WOFF/WOFF2) are compressed for network delivery. Desktop fonts (TTF/OTF) are uncompressed. Same visual quality, different optimization targets.

Question 32

Do you support TrueType Collections (.ttc)?

Accepted Answer

Not directly. Extract individual fonts from .ttc files first using specialized tools, then convert each font separately.

Question 33

What happens to font metadata during conversion?

Accepted Answer

Font name, copyright, vendor ID, version, and license URLs are preserved in the 'name' table during conversion.

Question 34

Can I convert PostScript Type 1 fonts (.pfb)?

Accepted Answer

Yes, we support PFB input. Note: Type 1 is deprecated (Adobe ended support in 2023) - convert to OTF or TTF for modern compatibility.

Question 35

What is kerning, and is it maintained?

Accepted Answer

Kerning = spacing adjustments between specific letter pairs (AV, To, etc.). Yes, all kerning data from 'kern' or 'GPOS' tables is fully preserved.

Question 36

How much will WOFF2 improve my page load speed?

Accepted Answer

Converting 4 fonts from TTF (400KB total) to WOFF2 (120KB total) saves 280KB = 1-3 second improvement on 3G connections, 0.5-1 second on 4G.

Question 37

What's the best font format for website performance?

Accepted Answer

WOFF2 - smallest file size (70% compression), modern browser support (96%), fast decompression, recommended by Google PageSpeed Insights.

Question 38

How many font files should I use per page?

Accepted Answer

Limit to 4-6 font files maximum (2 font families × 2 weights each). Every additional file adds ~30KB and an HTTP request.

Question 39

Should I preload web fonts?

Accepted Answer

Preload only critical fonts used above-the-fold (typically 1-2 files). Use in .

Question 40

What is font-display, and which value should I use?

Accepted Answer

CSS property controlling font loading behavior. Use font-display: swap - shows fallback text immediately, prevents invisible text (FOIT), best for Core Web Vitals.

Question 41

How do fonts affect Core Web Vitals?

Accepted Answer

Fonts impact LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift). Optimized WOFF2 + preloading + font-display: swap = better scores = higher rankings.

Question 42

What is the recommended total font size per page?

Accepted Answer

Target <150KB total (all fonts combined, WOFF2 format). Subsetting can reduce each font to 20-40KB.

Question 43

Do self-hosted fonts load faster than Google Fonts?

Accepted Answer

Yes, typically 200-500ms faster. Self-hosting eliminates external DNS lookup and gives you cache control. Use WOFF2 + proper caching headers.

Question 44

What is FOUT, and how do I prevent it?

Accepted Answer

Flash of Unstyled Text = fallback font briefly displays before web font loads. Prevent with font-display: swap (acceptable) or preloading (faster load).

Question 45

What is FOIT, and why is it bad?

Accepted Answer

Flash of Invisible Text = text hidden until font loads. Bad for UX and Core Web Vitals. Avoid by using font-display: swap or optional instead of block.

Question 46

Should I use font subsetting?

Accepted Answer

Yes, if serving specific languages. English-only subsetting reduces file size 50-70% beyond WOFF2 compression. Use our subsetting tool.

Question 47

How do variable fonts affect performance?

Accepted Answer

Variable fonts can reduce total size by 50-80% if you need 3+ weights. Single 120KB variable font replaces 9 × 100KB static fonts (900KB → 120KB).

Question 48

What's the optimal font loading strategy?

Accepted Answer

(1) Convert to WOFF2, (2) Subset for your language, (3) Preload critical fonts, (4) Use font-display: swap, (5) Serve from fast CDN or self-host.

Question 49

Do web fonts hurt mobile performance?

Accepted Answer

Only if unoptimized. Large TTF files (400KB+) on 3G = 5+ second load. WOFF2 + subsetting (100KB total) = minimal impact (<1 second).

Question 50

How do I measure font performance impact?

Accepted Answer

Use Google Lighthouse, WebPageTest, or PageSpeed Insights. Check LCP timing, CLS score, and total font download size. Target: all fonts load in <1 second.

Question 51

Is it legal to convert fonts I purchased?

Accepted Answer

Yes, IF your font license permits format conversion and web embedding. Check the EULA (End User License Agreement) - most allow conversion for web use.

Question 52

Can I convert free fonts from Google Fonts?

Accepted Answer

Yes, Google Fonts are licensed under the Open Font License (OFL), which permits conversion, modification, and redistribution.

Question 53

What is the Open Font License (OFL)?

Accepted Answer

Permissive license allowing free use, modification, and distribution. Fonts must remain under OFL when distributed. Cannot sell font files standalone, but can use them in commercial projects.

Question 54

Can I convert fonts and give them to clients?

Accepted Answer

Check your license. Desktop licenses usually allow installation on client computers. Web licenses allow embedding on client websites. Redistribution usually requires a separate license.

Question 55

Do I need a separate license for web fonts?

Accepted Answer

Usually yes. Desktop licenses cover installed fonts. Web/embedding licenses cover @font-face usage. Some foundries offer combined licenses.

Question 56

What are embedding permissions in fonts?

Accepted Answer

Flags in the OS/2 table controlling usage rights: Installable (full permissions), Restricted (no embedding), Preview/Print only, Editable embedding. Check with font tools.

Question 57

Can I convert Adobe Fonts?

Accepted Answer

Adobe Fonts terms allow web embedding via Adobe's service. Self-hosting converted files violates terms. Download button fonts may allow conversion - check individual license.

Question 58

Are all fonts on DaFont free to use commercially?

Accepted Answer

No. Many are "free for personal use" only. Check each font's license - commercial use often requires purchasing a license from the designer.

Question 59

What happens if I use fonts without proper licensing?

Accepted Answer

Copyright infringement. Font foundries can issue DMCA takedowns, cease-and-desist letters, or sue for damages. Fines can range from $150-$150,000 per infringement.

Question 60

Can I modify converted fonts?

Accepted Answer

Depends on the license. OFL allows modification. Commercial licenses usually prohibit modification unless you purchase an "editable embedding" license.

Question 61

Do I need to credit font designers?

Accepted Answer

Required for OFL fonts (include license file). Commercial fonts usually don't require credit, but check the EULA. Good practice: always credit designers.

Question 62

Where can I check font licensing?

Accepted Answer

Read the EULA when purchasing. Use font tools to check OS/2 fsType bits. Contact the font foundry if unclear. When in doubt, assume conversion/embedding requires permission.

Question 63

Do all browsers support WOFF2?

Accepted Answer

96% of browsers support WOFF2. Supported: Chrome 36+, Firefox 39+, Safari 12+, Edge 14+, Opera 23+. Not supported: IE11 and older.

Question 64

Which browsers need WOFF fallback?

Accepted Answer

Only IE9-11 (<0.2% global traffic). WOFF supported: IE9+, all modern browsers. If not supporting IE, WOFF2 alone is sufficient.
