What is the difference between WOFF and TTF?

WOFF is a web font format: a TrueType or OpenType font wrapped in zlib compression for delivery over HTTP. It was the web standard before WOFF2 and is now mainly a fallback for older browsers. TTF is the TrueType font container, using quadratic Bézier outlines. It installs on every desktop operating system and is the format design and office applications expect, though it is uncompressed and therefore inefficient on the web.

Anything to watch out for with TTF?

TTF and OTF are both SFNT containers. The practical difference is the outline type inside — quadratic for TrueType, cubic for PostScript. Converting OTF to TTF changes the container but does not resample the outlines; text renders identically.

Does converting a font affect how it renders?

No. All four formats here are containers around the same glyph outlines and OpenType tables, and the conversions are lossless — text renders identically before and after. What changes is file size and where the file can be used: browsers want WOFF2, operating systems want TTF or OTF.

Am I allowed to convert this font?

That depends on the font's licence, not on the tool. Many commercial licences permit desktop use but restrict web embedding, or the reverse. Converting the file does not change what the licence allows — check it before deploying a converted font to a website.

What should I know about starting from WOFF?

WOFF is a zlib-wrapped SFNT from the pre-2018 web. The wrapper is lossless, so the original font comes back out unchanged. More broadly: WOFF is an SFNT font wrapped in zlib compression plus a metadata block, designed specifically for web delivery. It was the web font standard from roughly 2012 until WOFF2 replaced it.

When is TTF the right choice?

TTF suits: installing a font locally for design or office software; any tool that rejects web font formats. It is the wrong choice when web delivery, where WOFF2 is roughly half the size for identical rendering.

Is there a file size limit?

No hard limit — the constraint is your browser's memory. Files under 50MB convert in a few seconds. Larger files work but take longer, and a browser tab typically has 250-500MB to play with, so very large batches are better split into smaller groups.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and the conversion runs on-device exactly as it does on desktop. Large files are slower on a phone because there is less CPU and memory available, but nothing about the workflow changes.

Overview

Why convert WOFF to TTF

Operating systems will not install a web font. If you need this typeface in Figma, Illustrator, Word or anywhere outside a browser, it has to be TTF or OTF first. WOFF is a zlib-wrapped SFNT from the pre-2018 web. The wrapper is lossless, so the original font comes back out unchanged.
