Frequently Asked Questions
Yes — completely free, no limits, no watermarks, and no account required. Convertlo runs entirely in your browser, and your font files never leave your device.
No. Conversion happens locally in your browser using WebAssembly. Your fonts never leave your device, so there is no file-size limit and nothing is stored anywhere — important for licensed or proprietary fonts.
WOFF2 is the modern web font format. It uses Brotli compression to make fonts about 30% smaller than WOFF and far smaller than raw TTF/OTF, which speeds up page loads. It is supported by every modern browser, so it is the recommended format for @font-face on websites.
Yes. Drop a WOFF2 (or WOFF) file, choose TTF as the output, and download an installable desktop font. This is handy when you have a web font but need to install it on your computer or open it in a design app.
You can convert between TTF, OTF, WOFF, and WOFF2. Common paths include TTF to WOFF2 and OTF to WOFF2 for the web, and WOFF2 to TTF to get an installable font back. The tool detects your input format automatically.
No. Converting between these formats repackages the same glyph outlines and metrics — the letterforms, spacing, and OpenType features are preserved. WOFF and WOFF2 are compressed containers, so the rendered font is identical to the original.
