WHY CONVERT
Why Convert JPG to AVIF?
AVIF uses modern compression that can cut website image weight, save storage and bandwidth, and modernize photo assets for current browsers — without uploading your photos to a conversion server.
PRIVATE IMAGE CONVERSION
Convert JPG and JPEG images to AVIF online. Reduce image file size while controlling AVIF quality — no signup required.
Upload JPG or JPEG photos and convert them to a modern, efficient format — free and processed locally in your browser.
Smaller files · Adjustable quality · No signup required
Savings depend on image content and quality. Your JPG is already compressed, so conversion cannot restore detail the original file discarded.
Supports .jpg and .jpeg · No signup required · Convert multiple files · 25 MB and about 24 megapixels each · Up to 20 files or 100 MB at a time
Files are processed locally in your browser. They are not uploaded to our server.
THREE STEPS
Drop files here or select them from your device. Conversion starts automatically.
Pick High, Balanced, or Smaller file to balance visual quality and size, then the files convert again with the new setting.
Download each AVIF file or get all ready results in a ZIP.

WEB DELIVERY
Serving AVIF where browsers support it often means fewer bytes for the same visual quality. Keep JPG as a fallback when you still need maximum compatibility.
HONEST TRADE-OFF
Use the quality presets to decide how aggressively AVIF compresses. Higher quality creates larger AVIF files; lower quality prioritizes size.
FILE SIZE
AVIF can often produce smaller files than JPEG at comparable visual quality, but the actual savings depend on the image content and quality settings.
Example. Your own original and AVIF sizes appear next to each result after conversion.
AT A GLANCE
| Feature | JPG/JPEG | AVIF |
|---|---|---|
| Compression | Can reduce quality to shrink size | Often smaller; can also keep full quality |
| Transparency | No | Yes |
| HDR | Limited | Supported |
| Modern compression | Older | Newer |
| Conversion speed | Fast | Often slower |
| Typical web compatibility | Works almost everywhere | Best in current browsers |
| File efficiency | Good | Often better |
AVIF does not always replace JPG. Convert when you want smaller modern web delivery and the audience supports AVIF. Keep JPG when you need the widest possible compatibility or a format every tool opens without conversion.
QUALITY
Convert JPG to AVIF while keeping high visual quality by choosing a higher quality preset. We open your JPG and save it again as AVIF — that cannot bring back detail the original file already lost.
Choose a high quality setting to keep more detail. Lower settings trade sharpness for smaller files.
COMMON QUESTIONS
Drop one or more JPG or JPEG files into the converter, choose an AVIF quality level if you like, and download each result or grab a ZIP of the ready files. Everything runs locally in your browser.
Yes. JPG and JPEG refer to the same JPEG image format, and both .jpg and .jpeg files are supported on this page.
Yes. You can convert JPG and JPEG files without creating an account, and there is no daily limit.
Often, yes — AVIF can produce smaller files than JPEG at comparable visual quality. Actual savings depend on the image content and the quality setting you choose. Your own original and AVIF sizes appear next to each result.
JPG files are already compressed, so conversion cannot restore detail the original file discarded. Saving as AVIF can soften the image a little more at lower quality. Choose High (85) to keep more detail, or Balanced (70) / Smaller file (50) when file size matters more.
Start with Balanced (70) for most photos. Use High (85) when you want to keep more detail, or Smaller file (50) when bandwidth and storage matter more than fine texture.
Yes. You can convert multiple JPG files at once within the limits shown in the uploader, and download all ready AVIF files together as a ZIP.
JPG/JPEG is an older photo format that opens almost everywhere. AVIF is newer, often smaller at similar quality, and can keep transparent backgrounds and richer color — and it works in current browsers.
