Convert font files for web and desktop.
Convert TTF, OTF, WOFF and WOFF2 files locally in your browser, preview the typeface, and copy a practical @font-face rule without uploading the font to NexFonts.

After converting to WOFF or WOFF2, place the file in your project and use this font face rule. Update the path when your font lives in a different folder.
@font-face {
font-family: 'Converted Font';
src: url('./converted-font.woff2') format('woff2');
font-display: swap;
font-style: normal;
font-weight: 400;

TTF and OTF are common desktop font formats. WOFF and WOFF2 are web-delivery formats, with WOFF2 usually the better starting point for a modern website because it is compressed specifically for browser delivery. Convert only the weights you need, keep the original font files, and verify that the licence permits web embedding or modification.
A TTF to WOFF2 or OTF to WOFF2 conversion is useful when you legally own or may use a desktop font and the licence also permits self-hosting on the web. It does not automatically make a desktop licence valid for a website. Commercial foundries can sell separate desktop, web, app or server rights, while open-source licences may permit much broader use. The original EULA or licence remains the authority after conversion.
WOFF2 should normally be your first web format for current browsers. WOFF can be retained only when a project has a specific legacy-support requirement. For a production site, load the minimum number of families, styles and weights required by the design, use accurate font-weight and font-style declarations, and consider subsetting only when the licence and workflow allow it.
Converting WOFF2 to TTF or another desktop format may help with a controlled local workflow, but it cannot restore information that was removed from the source or repair malformed outlines. Likewise, converting TTF to OTF changes the file container and compatibility context; it does not magically add professional OpenType features that were absent from the original typeface.
After conversion, preview real headings, paragraphs, numerals, accented characters and punctuation. Check the exact languages the project needs and compare the output against the untouched source file. A successful conversion should preserve the usable glyphs and metrics, but testing catches unsupported, damaged or unusual fonts before they reach production.
For web deployment, keep the source and licence in your private project archive, serve only the files the licence allows, and use the generated @font-face rule as a starting point rather than a complete performance strategy. Good font delivery also depends on caching, sensible fallbacks, preload choices and avoiding unnecessary weights.
Font conversion questions
Which font formats can I convert on NexFonts?
The converter can read TTF, OTF, WOFF and WOFF2 files up to 25 MB. It can create TTF, WOFF or WOFF2 output, depending on the source file and what the browser conversion engine can process.
Are my font files uploaded to a server?
No. The conversion runs in your browser, so the selected font is processed on your device. The preview and converted download use local browser object URLs rather than uploading the font to a NexFonts storage endpoint.
Should I use WOFF2 or WOFF on a website?
WOFF2 is the normal first choice for modern web projects because it is designed for efficient web delivery. WOFF can still be useful as a fallback when a project has older browser requirements.
Does converting TTF or OTF to WOFF2 change the font licence?
No. The original licence still controls whether the font can be converted, embedded or used on a website. Keep the licence and source information with the converted files.
Can font conversion fix a damaged or incomplete font?
No. Conversion changes the file format, not the quality of the outlines, kerning or character set. If the source font is damaged or missing glyphs, use a clean authorised copy instead.
