  • +Efficient compression for photographs
  • +Widely recognized file extension

Cons

  • -Some older systems prefer .jpg extension
  • -Quality loss with repeated editing

Frequently asked questions

Is it safe to convert JPEG to AVIF online?
Yes, Convt processes your files entirely in your browser using WebAssembly. Your files never leave your device - no data is uploaded to any server. This makes it completely private and secure.
How long does JPEG to AVIF conversion take?
Conversion is typically instant for small to medium files. Larger files may take a few seconds depending on your device's processing power. Since everything runs locally, speed depends on your hardware rather than internet connection.
Is there a file size limit for conversion?
There's no artificial file size limit. However, very large files (over 500MB for video, 100MB for images) may strain your browser's memory. For best results, ensure you have enough available RAM.
Do I need to install any software?
No installation required. Convt runs entirely in your web browser. It works on any modern browser including Chrome, Firefox, Safari, and Edge on desktop and mobile devices.
Can I convert multiple files at once?
Yes, you can add multiple files to the converter and process them all. Each file will be converted individually and you can download them separately or together.
Will converting JPEG to AVIF reduce image quality?
AVIF uses lossy compression, which may slightly reduce quality in exchange for smaller file sizes. For most uses, this difference is imperceptible.
