About This Tool
If you’re sitting on a folder of JPG photos taking up gigabytes of
space, converting them to AVIF can shrink that footprint
dramatically — often by 50% or more — without a visible drop in
quality. This tool converts your JPG images to AVIF entirely inside
your browser: drop them in and conversion starts immediately, with a
quality slider so you can control the size-versus-sharpness
trade-off yourself.

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up and no limit on how many images you convert.
Are my images uploaded to a server?
No. Every image is converted locally in your own browser and never leaves your device.
Will I be able to open AVIF files later?
AVIF is supported in all current major browsers (Chrome,
Firefox, Safari, Edge), and support in photo editors and OS
file previews is growing. If you’re archiving originals you may
never need to edit again, AVIF is a great space-saving choice;
if you’ll be actively editing them in older software, keep the
JPG.
Will AVIF look worse than my original JPG?
At the default quality setting, the difference is generally
invisible to the eye while the file is significantly smaller. A
live preview shows you the result before you download, so you
can raise the quality slider if you want to be extra safe.
Can I convert a whole folder of JPGs at once?
Yes — drop in as many as you like and each one converts automatically, with no batch limit.
Can I convert JPEG files too?
Yes, .jpg and .jpeg are the same format — both work with this tool.
