Frequently asked questions
How does AVIF Compressor work?
Drop your file, pick a quality target and hit Compress. The optimized file downloads straight from your browser. Nothing is uploaded.
Is AVIF Compressor free?
Yes, completely free with no watermarks or limits, because all processing runs on your own device.
Are my files safe?
Your files never leave your device. Compression happens locally in your browser via WebAssembly.
Is there a file size limit?
We impose no fixed limit. The practical ceiling is your device's free memory, since processing happens locally. Most conversions work comfortably with files up to a few hundred megabytes, and image or document conversions handle much more.
Does it work on my phone?
Yes. The converter runs in any modern browser on Windows, macOS, Linux, Android and iOS. No app installation is required.
