How do I convert WOFF to TTF?

Add your WOFF file to the upload area above, then press Convert. The TTF file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to TTF reduce quality?

No. TTF is a lossless format, so the conversion preserves exactly what is in your WOFF file. Note that it cannot recover detail that was already discarded when the WOFF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 40 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

WOFF and TTF explained

WOFF wraps a TrueType or OpenType font with compression and metadata, specifically for delivery over the web.

TrueType describes glyph outlines with quadratic curves and includes hinting instructions that improve rendering at small sizes on low-resolution screens.

Where WOFF files come from: Web font services and site asset pipelines.
Where TTF is used: System fonts and font downloads for desktop installation.

WOFF vs TTF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

WOFF compared with TTF
Property	Source	Target
Compression	Lossless	None
Introduced	2009	1991
Browser support	All browsers including old ones.	Every operating system.

WOFF is stronger at: Compressed for the web. Supported by every browser including very old ones. Carries licensing metadata.
TTF is stronger at: Installs on every operating system. Detailed hinting for small-size rendering. Widely supported by design software.

Why convert WOFF to TTF?

People make this switch when they run into the limits of WOFF: modern sites — WOFF2 is smaller and universally supported. TTF is the better fit when installing a font on a computer or using it in design software.

WOFF limitations that prompt the switch: Around 30% larger than WOFF2. Superseded for any modern browser target.
What you give up: Uncompressed, so it wastes bandwidth as a web font. Fewer advanced typographic features than OpenType.

What is preserved when converting WOFF to TTF?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
