About This Tool
AVIF is the most space-efficient image format widely available today
— often 50% smaller than JPEG at the same visual quality, which means
faster page loads and better Core Web Vitals scores. This tool
converts your JPEG 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.
Key Features

No upload step and no button to click — conversion starts the
moment you add an image.
Private & Secure
Your files never leave your device — nothing is ever uploaded to a server.
Batch Processing
Convert a handful of images or hundreds at once — there’s no batch limit.
Maximum Compression
AVIF typically beats both JPEG and WebP on file size at the same visual quality.

Compatible with desktop, tablet, and mobile browsers — no app to install.
Completely Free
No subscriptions, registrations, sign-ups, or hidden limits.

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 AVIF images work on my website?
AVIF is supported in all current major browsers (Chrome,
Firefox, Safari, Edge). Some older browsers, apps, and photo
editors don’t support it yet — if compatibility matters more
than file size for a particular image, keep the original JPEG
as a fallback, or use our AVIF to JPEG tool to convert back.
Will AVIF look worse than my original JPEG?
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.
Why is AVIF better than WebP?
AVIF generally achieves smaller file sizes than WebP at the same
visual quality, though WebP has been supported by browsers for
longer. If you need the absolute widest compatibility today,
WebP is the safer middle ground; if you want the smallest
possible files, AVIF is the newer, more efficient choice.
Can I convert multiple JPEG images at once?
Yes — drop in as many as you like and each one converts automatically, with no batch limit.
