Convert JPG to AVIF: how it works
What AVIF is for
AVIF is a newer image format that is often smaller than both JPG and WebP at the same visible quality. It supports transparency and wide colour. Current Chrome, Edge, Firefox and Safari can display it, which makes it a good choice for photos on websites where size matters.
How to convert
Drop your JPG or PNG files. AVIF is preselected, with a quality of 60, which is usually enough since AVIF looks good at lower numbers than JPG. Move the slider to find the smallest size that still looks right; each image shows its size before and after.
Encoding AVIF takes longer than JPG, especially for large photos, so a big batch can take a while. It all happens on your device, and nothing is uploaded.
When not to use it
Older software and some social sites and email clients cannot open AVIF. Keep a JPG for those, and use AVIF where you control the page.
What it does
What you can do with your images
Convert iPhone photos, shrink files for email or the web, and crop to an exact size, one image or a whole batch at a time. Your images never leave your device.

01
Convert HEIC photos to JPEG or PNG
iPhones save photos as HEIC, which Windows, many websites and older apps can't open. Convert them to JPEG for sharing, or PNG when you need lossless quality. It works in Chrome, Edge and Firefox as well as Safari.
In your browser -
02
Make images smaller
Scale images down from 1% to 100% and set the quality for JPEG, WebP, AVIF and PDF. WebP and AVIF are usually far smaller than JPEG at the same quality. Each image shows its size before and after, like

Compress PNGs without losing anything
The PNG compression slider trades speed for size. The result is always pixel-for-pixel identical to the original: images with few colours are stored as a palette, and an alpha channel that isn't used is dropped.

Crop, rotate and flip
Drag a crop box or type exact pixel values, and lock it to 1:1, 4:3, 3:2, 16:9 or 9:16 for profile pictures, thumbnails and stories. Rotate in 90° steps, flip either way, and give any image its own scale.

05
Turn images into PDFs and icons
Save any image as a one-page PDF to email or upload where only documents are accepted, or as an ICO favicon with every standard icon size inside (16 px up to 256 px).

Work in batches
Drop a whole folder of photos, set the format once, and convert them all. Save them one by one or all together as a single
Save all as zip.zip.

Stays on your device
- Every step: reading, converting, cropping and saving. Private photos stay private.
- The converted copy leaves out the original's metadata, such as camera details and GPS location.
Sent to the server
- Nothing. Images are never uploaded.
Recorded
- Anonymous usage data: the file name, size and format of each image, the settings used and whether it worked.
- Never the image itself.

Questions
Asked often
Is AVIF better than WebP?
It is often smaller at the same quality, but slower to encode. Both are widely supported in current browsers.
Why is AVIF not in my format list?
The list shows only formats your browser can write. If AVIF is missing, update your browser or try another.
What quality should I use for AVIF?
Start around 60. AVIF holds up at lower values than JPG; raise it if you see banding in smooth areas.
Does AVIF keep transparency?
Yes. A PNG with transparency keeps it when converted to AVIF.
Why is AVIF conversion slower than JPG?
AVIF uses a more complex encoder to reach smaller sizes. It runs on your device, so a large batch takes longer on a slower computer.
Can I use AVIF on my website?
Yes, for current browsers. Many sites serve AVIF with a JPG fallback using the HTML picture element.
