TTF stores scalable outlines for glyphs using quadratic Bezier curves, providing crisp output at any size.

Frequently Asked Questions

Is converting TTF to OTF free?

Yes. This TTF → OTF converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert TTF to OTF?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my TTF files uploaded to a server?

No. Files never leave your device. The entire TTF → OTF conversion runs locally in your browser, so your data stays private.

Can I convert multiple TTF files at once?

Yes — batch conversion is supported. Add as many TTF files as you like and convert them to OTF in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting TTF to OTF lose quality?

No. OTF is a lossless format (or used in a lossless mode here), so the original data from your TTF file is preserved bit-for-bit in the converted result.

Does OTF support transparency?

No — OTF has no alpha channel. Transparent areas of your TTF file will be filled with a solid background colour in the converted file.

How will the file size change after converting TTF to OTF?

Both formats use comparable compression, so the OTF output will be similar in size to your TTF file — typically within 10–20% of each other.
