Frequently Asked Questions

Is converting JPG to AVIF free?

Yes. This JPG → AVIF 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 JPG to AVIF?

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 JPG files uploaded to a server?

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

Can I convert multiple JPG files at once?

Yes — batch conversion is supported. Add as many JPG files as you like and convert them to AVIF 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 JPG to AVIF reduce the quality?

Because both formats use lossy compression, the AVIF output will not bring back any quality that has already been lost in your JPG file. Avoid repeated re-encoding to keep the best quality.

Does AVIF support transparency from JPG?

Yes. AVIF supports an alpha channel, so any transparent regions of your JPG file will be preserved as transparent in the converted file.

How will the file size change after converting JPG to AVIF?

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