Why Convert WOFF to WOFF2?
Understand when and why this conversion makes sense for your workflow.
Converting Web Open Font Format 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.
Web Open Font Format has a known limitation: larger than WOFF2 which uses more efficient Brotli compression. In contrast, Web Open Font Format 2 offers a key advantage: best compression of any web font format, 30% smaller than WOFF. While Web Open Font Format is commonly used for web font delivery via css @font-face rules, 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 WOFF source, ready to embed in your website or deploy in your design pipeline.

How to Convert WOFF to WOFF2
Follow these simple steps to convert your file in seconds.
Upload your WOFF font file
Upload the .woff 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 Web Open Font Format 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 Web Open Font Format 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 WOFF to WOFF2
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
Web Open Font Format has a known limitation: larger than WOFF2 which uses more efficient Brotli compression. Web Open Font Format 2 addresses this with a key advantage: best compression of any web font format, 30% smaller than WOFF. Converting from WOFF 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
Web Open Font Format is most commonly used for web font delivery via css @font-face rules, 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 WOFF 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.

Source Format
Web Open Font Format
font/woffWOFF (Web Open Font Format) is a web font format that wraps TrueType or OpenType font data with additional compression and metadata in a web-optimized container. It was developed by the W3C to provide a standardized, compressed font format specifically for web delivery. WOFF typically achieves 40% compression compared to raw TTF/OTF files.
Advantages
- Significantly smaller file sizes than TTF/OTF for faster web page loading
- Standardized by the W3C with universal browser support
- Includes metadata for licensing and font origin information
Limitations
- Larger than WOFF2 which uses more efficient Brotli compression
- Not intended for desktop application use
- Requires decompression overhead when loading fonts
Common Uses
- Web font delivery via CSS @font-face rules
- Self-hosted web typography on websites and web applications
- Font distribution through web font services
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
