Not Recommended For
Document requires precise formatting
Font changes affect layout and spacing. Complex formatting may not survive conversion intact.
→ Edit fonts directly in the source application (Word, InDesign) where you have full formatting control.
Working with legal or official documents
Official documents often require specific formatting and fonts that must remain unaltered.
→ Keep original documents as-is or consult document requirements before modifying.
Need to preserve embedded signatures or forms
PDF forms and digital signatures may be affected by font conversion.
→ Use PDF editing software that preserves form fields and signatures.
Document contains scanned images only
Scanned PDFs are images of text, not selectable text that can be re-formatted.
→ Use OCR software first to convert scans to text, then convert fonts.

Frequently Asked Questions
Everything you need to know about using this tool
Troubleshooting Guide
Common issues and how to resolve them
Font not applying to entire document
This can happen with complex PDFs that have multiple font layers. Try converting a simpler document first to verify. For heavily formatted documents, some sections may retain original styling. Consider exporting to a simpler format (like TXT or basic DOCX) before conversion.
Upload fails or times out
Check your file size - maximum is 50 MB. Ensure you have a stable internet connection. Try compressing large PDFs before upload, or convert to a lighter format like TXT or RTF first.
Downloaded file won't open
Make sure you have the appropriate software to open the file format (PDF reader, Word, text editor). Try downloading again - the file may have been corrupted during download. Check your download location for the complete file.
Custom font not recognized
Ensure your font file is in TTF or OTF format. Some specialized font formats are not supported. The font file should not be corrupted or password-protected. Try a different font file to verify.
Formatting looks different after conversion
Font changes naturally affect document layout. Larger fonts require more space, causing line breaks to shift. This is normal behavior. For precise formatting, consider the target font size when designing original documents.
