What is a AVIF file?
AVIF is built on the AV1 video codec and delivers the strongest compression of any mainstream image format — files are often about half the size of an equivalent JPG and noticeably smaller than WebP at the same visual quality. It supports transparency, HDR, and wide color gamuts.
In short, AVIF is the newest web format with the best compression available. It is best for performance-critical websites where every kilobyte counts, and modern image pipelines that can serve fallbacks. Its main limitations are encoding is slower than other formats, and very old browsers or desktop tools may not open AVIF files.
Why convert AVIF to JPG?
JPEG has been the default format for photographs since 1992. It uses lossy compression tuned for natural images, which lets it shrink photos to a fraction of their raw size while keeping them visually convincing. Virtually every camera, phone, browser, and app on the planet can open a JPG.
Converting from AVIF to JPG makes sense when you need photographs, screenshots of photos, email attachments, and anywhere maximum compatibility matters more than perfect fidelity. JPG is opened by every browser, OS, and image application ever made.
Note that JPG does not support transparency: any transparent areas in your AVIF will be filled with a white background during conversion.
For animated AVIF files, this tool converts the first frame — the output JPG is a still image.
How to convert AVIF to JPG
Drag and drop one or more AVIF files into the box above (or click to browse). Adjust the quality slider if you want smaller files or higher fidelity, then press Convert. Each file is decoded and re-encoded as JPG on your own device in a second or two, and you can download results individually or grab everything as a ZIP.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
