About the TTF to WOFF2 conversion
A practical look at what happens during this conversion, what to expect from the output, and the trade-offs involved.
TTF (TrueType Font) is the dominant desktop font format, designed for installation in operating systems and use across software applications. WOFF2 (Web Open Font Format 2) is a wrapper around TTF (or OTF) that uses Brotli compression to produce significantly smaller files specifically for web delivery. Converting TTF to WOFF2 is the standard step when deploying a custom font on a website.
The compression is lossless. Inside the WOFF2 wrapper is the same TTF font you started with — same glyph outlines, same kerning, same hinting, same OpenType features. The conversion just compresses the wrapper using a smarter algorithm. Decoding the WOFF2 produces a font that renders identically to the source TTF.
File size reduction is dramatic. A typical Latin-only TTF font might be 200-300 KB; the equivalent WOFF2 is typically 80-120 KB — about 60% smaller. For a font loaded on every page of a website, this directly affects page load speed and bandwidth costs. Modern sites typically include 4-6 web fonts (regular, bold, italic variants); the cumulative savings are substantial.
Browser support for WOFF2 is universal in 2026 — Chrome since 2014, Firefox since 2015, Safari since 2016, Edge since 2018. WOFF2 is the right web font format for any modern site. Older browsers that don't support WOFF2 (IE 11 and earlier) are below 1% global market share and not worth optimizing for.
Watch out
Verify the font license permits web embedding
TTF fonts purchased for desktop use often have licenses that explicitly forbid web embedding. Converting the TTF to WOFF2 doesn't grant a license you didn't have — it's still the same font. Before converting and deploying, check the EULA. Most font foundries sell separate desktop and web licenses; only fonts with explicit web licensing should be deployed as WOFF2 on a public website.
Pro tip
Subset the font to only the characters you need
A typical Latin-only website doesn't need a font that includes Greek, Cyrillic, CJK, and emoji characters. Subsetting the font (using a tool like glyphhanger or pyftsubset) before converting to WOFF2 reduces file size by 50-90% for most use cases. The resulting WOFF2 contains only the glyphs your site actually displays. Modern font subsetting tools can analyse your CSS to determine which characters you need.
When not to convert
When you should keep the TTF
For desktop installation, TTF is the right format. WOFF2 is web-only — it's not registered by operating systems or readable by desktop applications. Convert to WOFF2 only for web deployment. Keep the TTF as your master and re-subset/re-convert WOFF2 versions for each web project.
Why Convert TTF to WOFF2?
Understand when and why this conversion makes sense for your workflow.
Converting TrueType Font to Web Open Font Format 2 is a critical step in web typography and cross-platform font deployment. Font formats differ in browser support, file size, hinting quality, and licensing compliance. Web projects typically require fonts in specific formats for optimal rendering and performance, while desktop applications may need entirely different formats. Selecting the right font format reduces page load times and ensures consistent text rendering across all environments.
TrueType Font has a known limitation: larger file sizes than WOFF/WOFF2 for web delivery. In contrast, Web Open Font Format 2 offers a key advantage: best compression of any web font format, 30% smaller than WOFF. While TrueType Font is commonly used for desktop application and operating system fonts, Web Open Font Format 2 is better suited for primary web font format for modern websites.
Use MegaConvert to produce a properly structured WOFF2 file from your TTF source, ready to embed in your website or deploy in your design pipeline.

How to Convert TTF to WOFF2
Follow these simple steps to convert your file in seconds.
Upload your TTF font file
Upload the .ttf file you want to convert. Make sure you have the right to use the font in the format you are converting to — desktop font licenses do not always permit web embedding, and converting without an appropriate license may violate the terms of the font.
Click "Convert to WOFF2"
Press convert. Glyph outlines and metrics from your TrueType Font file are repackaged into the Web Open Font Format 2 container. Hinting is preserved when both formats support it. The conversion is essentially repackaging — no glyph data is regenerated, so the visual appearance is preserved exactly.
Wait for the conversion to complete
The conversion usually takes just a few seconds. The progress bar updates in real time while your TrueType Font file is processed and the new Web Open Font Format 2 file is generated.
Download your .woff2 file
When the conversion finishes, click the download link to save the new Web Open Font Format 2 file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.
Tips for Converting TTF to WOFF2
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
TrueType Font has a known limitation: larger file sizes than WOFF/WOFF2 for web delivery. Web Open Font Format 2 addresses this with a key advantage: best compression of any web font format, 30% smaller than WOFF. Converting from TTF to WOFF2 is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
TrueType Font is most commonly used for desktop application and operating system fonts, while Web Open Font Format 2 is the standard for primary web font format for modern websites. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where TTF is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the WOFF2 output
Web Open Font Format 2 has its own limitation worth understanding before you commit: not suitable for desktop application font installation. After the conversion completes, open the WOFF2 file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Check licensing before converting and deploying
Font licenses often restrict how and where a font can be used. A desktop font license may not permit web embedding, and converting a font to a web format without the appropriate license may violate the font's terms of use. Always verify your license covers the intended deployment method before converting.

Learn about the source and target file formats to understand what happens during conversion.
Source Format
TrueType Font
font/ttfTTF (TrueType Font) is a font format developed jointly by Apple and Microsoft in the late 1980s, using quadratic Bezier curves to define glyph outlines. It supports font hinting instructions that optimize rendering at small sizes on screen, and includes tables for kerning, ligatures, and other typographic features. TTF remains one of the most widely used font formats across all operating systems.
Advantages
- Universal support across Windows, macOS, Linux, and mobile operating systems
- Excellent screen rendering with built-in hinting instructions
- Well-established format with decades of tooling and ecosystem support
Limitations
- Larger file sizes than WOFF/WOFF2 for web delivery
- Quadratic curves are less efficient than cubic curves used in OpenType/CFF
- Single-style per file (no font collections without TTC container)
Common Uses
- Desktop application and operating system fonts
- Print document and graphic design typography
- Web fonts where WOFF/WOFF2 alternatives are not available
Target Format
Web Open Font Format 2
font/woff2WOFF2 (Web Open Font Format 2.0) is the successor to WOFF, using Brotli compression to achieve approximately 30% better compression than WOFF and over 50% reduction compared to raw TTF/OTF files. It is the recommended web font format for modern websites due to its superior compression and universal browser support. WOFF2 also includes font-specific preprocessing to further optimize compression.
Advantages
- Best compression of any web font format, 30% smaller than WOFF
- Universal support in all modern web browsers
- Font-specific preprocessing optimizes compression beyond generic algorithms
Limitations
- Not suitable for desktop application font installation
- Slightly slower to decompress than WOFF due to more complex compression
- Encoding requires more processing time than WOFF
Common Uses
- Primary web font format for modern websites
- Google Fonts and other web font service delivery
- Performance-optimized web typography for fast-loading pages
