Downloaded a product photo or wallpaper that turned out to be AVIF? JPG remains the format that everything accepts — from photo printers to visa application portals — and converting locally takes seconds.
Your browser decodes the AVIF natively and this tool re-encodes it as JPG at a quality you control. Transparent regions, if any, are filled with a background color you choose explicitly.

This is Convert Image Format preconfigured for this task — open the full tool for every option.
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
Usually yes — AVIF compresses better than JPG. You're trading some size for compatibility with software that hasn't caught up to AVIF yet.
No. Current browsers decode AVIF themselves; the re-encode to JPG also runs in your tab. The network panel shows no request carrying your image.
Technical guidance for choosing settings and reviewing the result.
There is no quality percentage that makes every image exactly 1 MB or 100 KB. A reliable target-size workflow measures real encodes, preserves the best result under the limit, and tells you when resizing is necessary.
