About this tool

AVIF is a modern image format that produces small files, but many photo editors, document tools, upload forms and older apps still cannot open it. This AVIF to JPG converter turns .avif files into standard JPEG images that work almost everywhere. Your browser decodes each AVIF and the tool re-encodes it as a JPG with the quality you choose, from 40 to 100 percent (92 by default). JPG cannot store transparency, so any transparent pixels are filled with a background colour you pick, white by default. You can convert several files at once and download each JPG separately or all of them as a ZIP. The pixel dimensions stay the same. Because decoding relies on your browser, you need a version that supports AVIF: Chrome 85 or later, Firefox 93 or later, or Safari 16 or later. Files are processed on your device and are not uploaded.

Why use it

  • Browser-only conversion: each AVIF is decoded and re-encoded as JPG on your device, so photos are never uploaded.

  • Batch friendly: select several AVIF files at once and download them one by one or together as a ZIP.

  • Same dimensions: the output keeps the exact pixel width and height of the source image.

  • Clear per-file results: each file shows a preview, its dimensions and the size before and after conversion.

  • No account, watermark or daily limit.

  • Adjustable quality from 40 to 100 percent, so you can trade file size for detail.

How to use

  1. Click the upload area or drag one or more .avif files onto it.
  2. Set the JPG quality and, if your images have transparent areas, the background colour.
  3. Press Convert to JPG and wait for each file card to appear.
  4. Download each JPG, or press Download all (ZIP) when you converted several files.

When it helps

  • You saved an image from a website and got an .avif file that your editor or viewer will not open.
  • A job portal, marketplace or form only accepts JPG uploads.
  • You want to insert AVIF images into Word, PowerPoint or an email that expects JPEG.
  • You are sending photos to someone whose phone or computer cannot display AVIF.

Tips

  • Keep the original AVIF if you may need transparency later; JPG cannot restore it.
  • For graphics with text or sharp edges, AVIF to PNG keeps edges crisper than JPG.
  • Lower the quality slider a little if the JPG files are too large for an upload limit.

Frequently Asked Questions

What is an AVIF file?
AVIF (AV1 Image File Format) is an image format based on the AV1 video codec. It usually makes smaller files than JPEG at similar visual quality and supports transparency and HDR, but software support is still less universal than JPG.
Are my images uploaded?
No. The browser decodes and re-encodes each file locally with the Canvas API. Only the ZIP helper library is downloaded from a CDN if you choose Download all.
Why did a file fail to convert?
The most common reason is a browser without AVIF support. Use Chrome 85+, Firefox 93+ or Safari 16+. A corrupted or mislabelled file will also fail, and the tool reports which file could not be decoded.
What happens to transparent areas?
JPG has no transparency, so transparent pixels are filled with the background colour you choose before encoding. Pick a colour that matches where the image will be placed.
Which JPG quality should I use?
The default of 92 percent keeps photos visually close to the source. Lower values make smaller files with more visible compression artefacts. 100 percent produces the largest files.
Will the JPG be larger than the AVIF?
Usually yes. AVIF compresses more efficiently than JPEG, so the same image as a JPG generally needs more bytes. Each file card shows the size before and after.
Is image metadata kept?
No. The image is redrawn on a canvas and exported, so EXIF data such as camera details and GPS location is not copied into the JPG.
