Make your JPGs a fraction of the size. Convert JPG to modern AVIF right here in your browser — same visual quality, much smaller files.
Your files never leave this device.jpg and .jpeg · up to 10 at once · 50 MB each
Four steps, a few seconds, zero uploads.
Drag images onto the box above, or click Browse to pick them from your device.
Pick an AVIF quality level — higher keeps more detail, lower makes smaller files. The default suits most photos.
Latch encodes each JPG to AVIF with the AV1 codec, right in your browser — instantly and offline.
Save them one at a time, or grab everything at once in a single zip. That's it.
JPG has been the default photo format for decades, but its compression is dated. AVIF, built on the modern AV1 codec, stores the same photo 30–50% smaller at the same visual quality — sometimes more. For websites, that means faster pages and better Core Web Vitals; for everyone else, it means more photos in the same storage and quicker uploads.
Both formats are lossy, so converting re-encodes the image. At a sensible quality the result is visually indistinguishable from the JPG while being far lighter. Bear in mind you can't recover detail the original JPG already discarded — AVIF simply stores what's there more efficiently.
The trade-off is reach: a few old browsers and legacy apps still don't open AVIF. Keep the original JPG if you need universal compatibility, or convert back any time with AVIF to JPG.
AVIF is typically 30–50% smaller than JPG at the same visual quality, because the AV1 codec compresses far more efficiently than the decades-old JPEG format. That makes pages load faster and saves storage and bandwidth.
AVIF re-encodes the image, so like JPG it's lossy. At the default quality the difference is very hard to see, and the file is much smaller. Raise the quality slider to preserve more detail. Detail already lost when the original JPG was saved can't be recovered.
All current browsers — Chrome, Edge, Firefox, and Safari 16 and later — display AVIF, and it's widely supported across the web. Some older apps, devices, or operating systems may not open it yet, so keep the original JPG if you need broad compatibility.
No. Every JPG is encoded to AVIF by your own browser. Nothing is sent to a server — in fact, the tool keeps working even with your Wi-Fi switched off.
Yes. Drop up to 10 JPG files at once and they'll all convert in one go. When done, download them individually or as a single zip file.
