Top 3 Font Converter Alternatives Worth Using
Heshan Fernando
Co-founder & COO
You have a font file in one format and need it in another, most often a TTF or OTF turned into WOFF or WOFF2 for a website, plus the CSS to load it.
The results for that search are a mixed bag. Some tools upload your file to a server, some cap the file size, and some are built for a full web-font workflow when you only wanted one conversion. Font licences also vary, so it matters whether your file leaves your machine.
How to judge a font converter
- Does it convert in the browser? Local processing means the font never leaves your device.
- Which formats does it really produce? WOFF2 needs Brotli compression, and not every tool does a real conversion.
- Does it give you the CSS? An
@font-facerule saves a step; see MDN’s @font-face reference for what the rule does. - What are the size limits? Per-file and per-batch caps decide whether your file fits.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| Fontsource | Fast in-browser conversion to WOFF2, WOFF or TTF | Free | Output options are WOFF2, WOFF and TTF |
| Transfonter | A full web-font kit with CSS, subsetting and demo page | Free | 5 MB per file, up to 20 files per conversion |
| Made Good Designs | Conversion plus a web-font kit and font-display choices | Free; no account | Similar breadth to a full toolkit, so more than a one-off needs |
Facts checked September 2026; tools change their plans. Table covers only the 3 alternatives — our tool gets its own section below instead of a 4th row.
Fontsource
Fontsource’s converter takes TTF, OTF, WOFF and WOFF2 input and outputs WOFF2 (its recommended choice), WOFF or TTF. Files are processed in your browser, you can download them individually or as a ZIP, and the page lists a 250 MB maximum file size. It is free.
It is a converter, not a web-font kit builder: if you also want subsetting, hinting options or a demo page, you will need another tool. The output list does not include OTF or older formats such as EOT.
Transfonter
Transfonter is the classic web-font generator. It accepts many input formats, including TTF, OTF, WOFF, WOFF2, SVG, TTC and DFONT, and outputs TTF, EOT, WOFF, WOFF2 and SVG. It generates @font-face CSS, offers hinting options, subsetting by Unicode range or character selection, base64 encoding and font metrics correction, and bundles everything in a zip with a demo page.
The page lists a 5 MB limit per file and up to 20 files per conversion. That is generous for most web fonts but rules out very large font families, and it does not describe itself as a local, in-browser tool.
Made Good Designs
Made Good Designs converts between TTF, OTF, WOFF and WOFF2 entirely in your browser; its page says nothing is sent to a server. It exports a web-font kit with matching @font-face CSS, lets you choose the font-display value, previews the font and compresses WOFF2 with Brotli. It also lists metadata inspection and subsetting, and says there are no watermarks or limits.
It is the closest in shape to a full toolkit, so if you only need to swap one file’s container, it offers more options than the job requires.
Font Converter
Our Font Converter lets you drop in a TTF, OTF, WOFF or WOFF2 file, preview it with your own text, read its family and glyph metadata, copy ready-made @font-face CSS and download a repackaged file. It runs in your browser, so the font is not uploaded.
Its main limit matters. TTF and OTF share a compatible container, so converting between them produces a genuinely usable file. But it does not recompress: choosing WOFF or WOFF2 as the target keeps the original font bytes under a new name and shows a note saying so. Metadata details are also not shown for WOFF2 files. If you need real Brotli-compressed WOFF2 output, use one of the alternatives above.
Which one to pick
- You need real WOFF2 output quickly: use Fontsource or Made Good Designs.
- You want subsetting, hinting and a demo page: use Transfonter.
- You want to preview a font, read its metadata and copy
@font-faceCSS: use our Font Converter. - You are swapping between TTF and OTF: our Font Converter repackages that genuinely.
How to do it with Font Converter
- Open the Font Converter and choose a .ttf, .otf, .woff or .woff2 file.
- Preview it with your own text and check the metadata shown.
- Pick a target format, then copy the
@font-faceCSS or download the file.

Web fonts are heavier than they need to be, so the Font Subsetter is a natural next step to trim unused glyphs. If you are still choosing type, the Font Pairing Tool helps with the step before conversion.
Frequently asked questions
Is there a free font converter that doesn’t need an account?
Yes. All three alternatives here are free, and Made Good Designs states that no account is needed. Our Font Converter has no accounts either.
Do online font converters upload my font file?
Some do and some don’t. Fontsource and Made Good Designs process files in your browser, and so does ours. Transfonter’s page does not describe itself as local processing.
Can I convert TTF to WOFF2 online?
Yes, with a tool that does real Brotli compression, such as Made Good Designs, and Fontsource lists WOFF2 as its recommended output. Our tool does not recompress files for WOFF or WOFF2 targets, so use it for TTF and OTF repackaging, previews and CSS.
Final thought
Choose by what you need out: real WOFF2 compression points to Fontsource or Made Good Designs, a full kit points to Transfonter, and a private preview with CSS points to our converter.
