Best Free Font Converters in 2026

You bought a font (or downloaded a free one) and it's a TTF file. Your website needs WOFF2. Your email template needs a web-safe fallback. Your legacy app requires EOT because apparently it's still 2012 somewhere.

Font conversion shouldn't be complicated, but the landscape of tools is surprisingly messy. Here's what actually works in 2026.

Font Formats: A Quick Primer

Before comparing tools, let's clarify what you're converting between:

Format	Full Name	Primary Use
TTF	TrueType Font	Desktop apps, older web fallback
OTF	OpenType Font	Desktop apps, advanced typography
WOFF	Web Open Font Format	Web (compressed TTF/OTF wrapper)
WOFF2	Web Open Font Format 2.0	Web (better compression than WOFF)
EOT	Embedded OpenType	Internet Explorer only (legacy)

For modern web development, WOFF2 is what you need. Browser support is universal now. WOFF is your fallback for very old browsers, and you can skip EOT entirely unless you're supporting IE 11 (and honestly, it's 2026 — you shouldn't be).

The Tools

1. MyPDF Font Converter

MyPDF handles TTF, OTF, WOFF, and WOFF2 conversions in the browser. No upload to servers, no account needed. Pros:

• Batch conversion — drop 20 fonts, get 20 converted files
• Preserves font metadata (name tables, license info)
• WOFF2 compression is properly optimized
• Clean, no-nonsense interface

Cons:

• No EOT output (but again, who needs EOT in 2026?)

2. CloudConvert

A general-purpose file converter that happens to support fonts. It handles the common formats and works well enough for one-off conversions.

Pros:

• Supports a wide range of formats including EOT
• API available for automation
• Reliable output quality

Cons:

• Free tier is limited (25 conversions per day)
• Files are uploaded to their servers
• Slower than browser-based tools — you're waiting for server processing

3. Transfonter

A web-based tool specifically designed for generating @font-face kits. It's been around for years and is popular with web developers.

Pros:

• Generates complete CSS @font-face declarations alongside the converted files
• Subsetting built in — strip unused character ranges to reduce file size
• Produces a ready-to-use web font package

Cons:

• Interface feels dated
• Limited to web font output (WOFF, WOFF2, EOT, SVG)
• Can't go the other direction (WOFF2 back to TTF)

4. FontForge

The open-source font editor. This is the power tool — it doesn't just convert fonts, it's a full font creation and editing suite.

Pros:

• Completely free and open source
• Supports every font format that exists
• Can edit glyph outlines, kerning tables, everything
• Scriptable with Python for batch operations

Cons:

• Steep learning curve — this is professional software
• Desktop application, not web-based
• UI looks like it was designed by engineers (because it was)
• Overkill if you just need to convert a file

5. Google Fonts

Not a converter per se, but worth mentioning: if your font is on Google Fonts, you already have WOFF2 files available. Download them directly instead of converting.

Subsetting: The Optimization Most People Skip

A typical font file contains glyphs for Latin, Cyrillic, Greek, Vietnamese, and more. If your website is English-only, you're shipping thousands of unused glyphs.

Subsetting strips the font down to only the character ranges you need. A 200KB WOFF2 file can drop to 20KB with proper subsetting. That's not a marginal improvement — it's an order of magnitude.

Both Transfonter and MyPDF offer subsetting as part of the conversion process. Use it.

The Practical @font-face Setup

Once you have your WOFF2 file, the CSS is simple:

@font-face {
  font-family: 'MyCustomFont';
  src: url('/fonts/my-font.woff2') format('woff2'),
       url('/fonts/my-font.woff') format('woff');
  font-weight: 400;
  font-style: normal;
  font-display: swap;
}

The font-display: swap line is important — it prevents invisible text while the font loads. Your visitors see a fallback font briefly, then it swaps to your custom font. Much better than a blank screen.

My Recommendation

For most web developers: MyPDF's font converter for quick TTF/OTF to WOFF2 conversion with subsetting. For font editing and advanced work: FontForge. For generating complete @font-face kits: Transfonter.

Skip EOT. It's 2026. Let IE go.
