This page indexes every font tool on Font-Converters, 17 of them. Each one does a single job: shrink a font file, generate the CSS that serves it, read what is inside it, check what its license allows, work out a type scale, re-typeset a document in a different face, or convert text into another character system.
The comparison table below lists all 17 with what each one takes in and what it hands back. Below that, the tools are grouped into 5 sections by the job you are trying to finish. Every tool is free, needs no account, and 12 of the 17 run entirely in your browser.

What each tool does, what you give it, and what you get back. Tool names link straight through.
| Tool | What it does | Input | Output |
|---|---|---|---|
| CSS @font-face Generator | Writes a production-ready @font-face rule with browser fallbacks | A TTF, OTF, WOFF, or WOFF2 file | CSS you can paste straight into a stylesheet |
| Webfont Generator | Builds @font-face CSS with Base64 embedding or a custom URL path | A font file, plus weight, style, and font-display settings | CSS with the font inlined or linked |

| Font Subsetter | Strips out glyphs you never render, to cut the file size | A font file, plus the characters or scripts to keep | A smaller font file, often 50 to 90 percent lighter |
| Drop Shadow Generator | Layers text-shadow effects and previews them in your own font | A font file, plus shadow color, blur, and offset | text-shadow CSS |
| Font Analyzer | Reads a font's internal metadata, metrics, and glyph coverage | Any font file | Glyph count, metrics, supported scripts, and name table data |
| Font Preview Generator | Renders your own sample text across sizes, weights, and styles | A font file, plus your own sample text | An on-screen waterfall preview |
| Variable Font Tester | Drives a variable font's axes live and exports the settings | A variable font file | Live preview plus font-variation-settings CSS |
| Font License Checker | Looks up what a font license permits, including commercial use | A font name, or a font file to read its embedded license | License type and the uses it permits |
| Font Size Converter | Converts a size between px, rem, and em | A size, plus the root font size to measure against | The same size expressed in all three units |

| Golden Ratio Calculator | Builds a whole type scale from one base size and a ratio | A base size and a ratio, 1.618 by default | Sizes for h1 to h6 as CSS custom properties |
| Dyslexia Font Converter | Re-typesets a document in a dyslexia-friendly typeface | A PDF, DOCX, or TXT file | The same document set in a dyslexia-friendly font |
| Braille Translator | Converts between text and braille across 30+ languages | Plain text, or braille characters | Braille output, or the text it spells |

| ASCII Converter | Converts text to ASCII codes and codes back to text | Text, or decimal, hex, or binary codes | ASCII codes, or the decoded text |
Everything needed to take a font file and ship it on a website: shrink it, encode it, and write the CSS that serves it.
Generate production-ready @font-face CSS for your web fonts. Upload any font file and get optimized CSS with format hints and browser fallbacks included.
Generate @font-face CSS with Base64 encoding and custom URL paths. Useful when you want the font embedded directly in the stylesheet instead of fetched separately.
Convert font files to Base64 strings for direct CSS embedding. Generate single-file solutions with the font data carried inside the stylesheet.
Generate unicode-range values for @font-face CSS. Use preset scripts or build a custom range to split a large font into per-script slices.
Reduce font file size by removing unused characters. Keep only the glyphs you need for faster page loads and better Core Web Vitals.
Create text-shadow CSS effects for your fonts. Upload any font, stack multiple shadow layers, and copy production-ready CSS.
Look inside a font file before you commit to it. Check what glyphs it carries, how it renders, and what the license allows.
Extract detailed information from font files including glyph count, metadata, supported scripts, and technical properties.
Preview fonts with various styles, sizes, and weights. Test fonts with custom sample text and a waterfall display before you commit.
Test variable fonts with real-time axis controls. Explore weight, width, and slant, then export the font-variation-settings CSS.
Check font licenses and understand usage rights. Search a database of popular fonts, or upload a font to read the license field in its metadata.
Work out sizes, weights, and scales. No font file needed, these run on numbers.
Convert font sizes between PX, REM, and EM units instantly. Set a custom base size so the conversions match your own stylesheet.
Find optimal font weights for different design contexts. Get recommendations for body text, headings, and UI labels, with CSS export.
Calculate typography scales using the golden ratio (1.618) or a custom ratio. Preview the result and export CSS for h1 through h6.
Reformat documents and text for readers who need a different typeface or a different medium entirely.
Convert any document to dyslexia-friendly fonts instantly. Make PDFs, Word docs, and text files easier to read for people with dyslexia.
Convert text to braille and braille back to text across 30+ languages, including English (Grade 1 and 2), Arabic, Hindi, Russian, Japanese, and Korean. Handles numbers, capitals, and punctuation.
Change the font a document is set in, or convert text between character systems and Unicode styles.
Convert PDF, DOCX, TXT, and more to any font. Upload your document, then choose a font from the library or supply your own.
Convert text to ASCII codes (decimal, hex, binary) and ASCII codes back to text. Includes the complete printable ASCII reference table.
12 of the 17 tools do all their work in your browser. Nothing is sent anywhere, and they keep working if you drop your connection after the page loads.
The remaining 5 need a server, because rewriting a PDF or rebuilding a font binary is not something a browser can do on its own. Those are the Font Subsetter, Font Analyzer, Font License Checker, Dyslexia Font Converter, and File Font Converter. They process your file in memory and hand back the result. The file is not written to disk and no copy is kept.
Three, in this order. Run the file through the Font Subsetter first, because unused glyphs are where most of the weight sits. Then use the CSS @font-face Generator to write the rule that serves it, with the right format hints and fallbacks. If your pages cover more than one script, the Unicode Range Generator splits the font so a browser downloads only the ranges a given visitor actually renders. The Font Analyzer is worth a look before any of that, to confirm the file really carries the weights and characters you are expecting.
Yes. All 17 are free to use with no account, no email address, no trial period, and no cap on how many times you run them. The site is funded by advertising, not by charging for the tools.
Most of them never leave your computer. 12 of the 17 tools run entirely in your browser. The other 5, the File Font Converter, the Dyslexia-Friendly Document Converter, the Font Subsetter, the Font Analyzer, and the Font License Checker, need a server to do the work, so they send your file to our API. Those files are processed in memory and the result is returned to you, without being written to disk or kept afterwards.
The converter on the home page changes a font file from one format into another, such as TTF to WOFF2. The tools on this page do everything else: shrinking font files, generating CSS, reading metadata, checking licenses, converting documents, and restyling text. If a different file format is all you need, start with the converter instead.
Longer walkthroughs for the workflows the tools above only handle one step of.
These tools cover everything except changing a font from one file format to another. That lives elsewhere on the site.
