Is the AVIF to JPG converter free?

Yes. Transcodr is free with no accounts, watermarks, or hard limits beyond your device's available memory.

Are my files uploaded to a server?

No. The conversion runs locally via ffmpeg compiled to WebAssembly, so your AVIF file never leaves the browser tab.

Is transparency preserved when converting to JPG?

JPG has no alpha channel, so transparent areas become a solid background. Convert to PNG or WebP if you need to keep transparency.

How do I convert AVIF to JPG?

01 / Engine

Real ffmpeg, compiled to WebAssembly.

Same library Netflix, YouTube, and basically every command-line video tool relies on, running in a Web Worker. Pipe a file in, run a command, pipe bytes back out.

02 / Privacy

Nothing leaves the tab.

No uploads, no accounts, no telemetry beyond an anonymous pageview. We couldn’t see your files if we wanted to — there’s no server in the loop.

03 / Limits

It is, after all, a tab.

Files up to a few hundred megabytes convert comfortably. Beyond that, your browser starts asking pointed questions. Use the desktop ffmpeg for 4K masters.
