Why Convert TTF to WOFF?
Understand when and why this conversion makes sense for your workflow.
Converting TrueType Font to Web Open Font Format 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 offers a key advantage: significantly smaller file sizes than TTF/OTF for faster web page loading. While TrueType Font is commonly used for desktop application and operating system fonts, Web Open Font Format is better suited for web font delivery via css @font-face rules.
Use MegaConvert to produce a properly structured WOFF file from your TTF source, ready to embed in your website or deploy in your design pipeline.

How to Convert TTF to WOFF
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 WOFF"
Press convert. Glyph outlines and metrics from your TrueType Font file are repackaged into the Web Open Font Format 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 file is generated.
Download your .woff file
When the conversion finishes, click the download link to save the new Web Open Font Format 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 WOFF
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 addresses this with a key advantage: significantly smaller file sizes than TTF/OTF for faster web page loading. Converting from TTF to WOFF 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 is the standard for web font delivery via css @font-face rules. 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 WOFF output
Web Open Font Format has its own limitation worth understanding before you commit: larger than WOFF2 which uses more efficient Brotli compression. After the conversion completes, open the WOFF 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
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
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
