Question 1

Is this free?

Accepted Answer

Yes, completely free, with no sign-up and no limit on how many fonts or how many times you use it.

Question 2

Is my font file uploaded to a server?

Accepted Answer

No. Every conversion runs entirely on your device using WebAssembly — your font file is never uploaded anywhere.

Question 3

Do I need to install anything?

Accepted Answer

No. Every tool runs directly in your web browser using WebAssembly — there's nothing to download or install.

Question 4

Is there a limit on file size or how many times I can use these tools?

Accepted Answer

No hard limit — font files are small, so conversion is near-instant even for large batches.

Question 5

What font formats are supported?

Accepted Answer

TTF, OTF, WOFF, and WOFF2 as input. OTF can only be converted, not converted to — it can be a source format, but not a target, since it uses PostScript outlines this tool converts to TrueType outlines on read.

Question 6

Does this work on mobile?

Accepted Answer

It works in any modern browser with WebAssembly support — Chrome, Safari, Firefox, and Edge on both desktop and mobile.

Question 7

How is this free?

Accepted Answer

Because all processing happens in your browser, there's no server cost per file. The site is supported by advertising rather than charging per use.
