Font preview guide
Use this tool to inspect an uploaded font with your own sample text before using it in a design or web project.
How it works
The browser creates a temporary font face from the uploaded file and applies it to the live preview text without uploading the font anywhere.
Supported files
Upload TTF, OTF, WOFF, or WOFF2 files. If the browser can read the font, the preview updates immediately.
Privacy and limits
The font stays in your browser. This preview does not change the file, optimize it, or check whether your license allows web or commercial use.
Common issues
- Corrupted or unsupported font files may not render in the preview.
- Some fonts contain limited character sets, so test the exact text you plan to use.
- Browser rendering can differ slightly from design tools or operating system previews.
Next step
Ready to use the font on a website? Convert it with Font to Webfont, then generate CSS with Font CSS Generator.
Before you ship webfonts
A font file can convert successfully and still be wrong for a website if the license, character coverage, weight selection, or CSS loading strategy is not ready. Test headings, body copy, numbers, and accented characters before publishing.
Treat conversion as one part of the webfont job. The final setup also needs correct file paths, fallback fonts, caching, and a font-display choice that matches the site. If the font is only used for headings, avoid shipping unnecessary weights that slow down every page.
- Confirm the license allows web use.
- Ship only the weights and styles the site needs.
- Use CSS with sensible fallback fonts and a clear font-display choice.
After downloading the result, open it once before using it in a client send, upload form, website, or archive. This final check catches format support issues, unexpected file size changes, missing characters, clipped media, or page-order mistakes while the original file is still available.
If the output will be reused, note the settings that produced it. That makes the next export easier to repeat and reduces guesswork when another file needs the same treatment.
