To convert AVIF to JPG online, add your AVIF files above, choose a quality (90 suits most images), pick a background colour for transparent areas, press Convert and download the JPG files. HDR and 10-bit images are reduced to standard 8-bit colour. Nothing is uploaded.
Convert AVIF images to JPG so they open in older editors, upload to any platform and print anywhere. A quick fix for pictures saved from modern websites. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online converters, this tool does not upload your images. Your browser decodes each AVIF file, converts it and creates the JPG file on your own device. That keeps private photos private, avoids upload waits and keeps working on a slow connection once the page has loaded. You can convert up to 50 files at a time and download them one by one or together as a ZIP.

This table compares the two formats so you can decide whether converting is the right move.
| Feature | AVIF | JPG |
|---|---|---|
| Full name | AVIF (AV1 Image File Format) | JPEG (Joint Photographic Experts Group) |
| Origin | Specified by the Alliance for Open Media in 2019 | Standardised in 1992 |
| Compression | Lossy and lossless | Lossy |
| Transparency | Yes | No transparency |
| Animation | Yes | No |
| Colour depth | 8, 10 and 12 bits; HDR capable | 8 bits per channel (24-bit colour) |
| Typical file size | Often the smallest of the common formats | Small for photographs |
| Best for | High-quality web images where file size matters most | Photographs and images with many colours |
| Browser support | Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+ | Every browser, app and device |
| File extension | .avif | .jpg, .jpeg |
File size: JPG files are usually larger than the AVIF they came from, because AVIF compresses more efficiently.
This is exactly what happens to your file. Nothing is hidden, and you can verify that nothing is uploaded by watching your browser's network tab while you convert.
| Step | What happens |
|---|---|
| 1. Read the file locally | Your browser reads the file from your device into memory. Nothing is sent to a server. |
| 2. Identify the format | We check the file's first bytes (its signature) instead of trusting the extension, so a PNG renamed to .jpg is still handled correctly. |
| 3. Decode the AVIF to pixels | The image is decoded to raw red, green, blue and alpha pixels using your browser's built-in AVIF decoder (a bundled WebAssembly decoder steps in if the browser has none). |
| 4. Resize (optional) | If you set a maximum width, larger images are scaled down with an area-weighted filter. Images are never enlarged, and the proportions are always kept. |
| 5. Flatten transparency | JPG cannot store transparency, so each pixel is blended with your chosen background colour: result = colour × α + background × (1 − α) for every channel, where α runs from 0 (transparent) to 1 (opaque). |
| 6. Encode the JPG | The pixels are written out as JPG using your browser's JPEG encoder, using the quality you set. Metadata such as camera details and location is not copied. |
| 7. Report the result | We show the dimensions, the sizes before and after, and the change: (new size − original size) ÷ original size × 100. For example, 500 KB becoming 350 KB is −30%. |
| Setting | Default | Range | What it does |
|---|---|---|---|
| Quality | 90 | 1–100 | Higher gives a sharper, larger JPG. 85–92 suits most photos. |
| Background colour | White | Any colour | Fills transparent areas, since JPG cannot store transparency. |
| Maximum width | None | 1–20,000 px | Scales larger images down. Never enlarges. |
| What | Formula | Notes |
|---|---|---|
| Size change | (new − original) ÷ original × 100 | Shown for every file. Negative means smaller. |
| Transparency | colour × α + background × (1 − α) | Per colour channel; α from 0 to 1. |
| Downscale factor | min(1, maximum width ÷ width) | Applied only when you set a maximum width; never above 1. |
| Quality | Passed to the encoder as a number from 1 to 100 | The scale is encoder-specific, so the same number gives different results in different formats. |
Speed depends on your device and the image size. In our Chrome tests on a desktop-class processor, a 6-megapixel photograph took about 2 seconds to convert to WebP or PNG. AVIF is the slowest: about 2.5 seconds on Fast and about 7.5 seconds on Balanced. Phones and older laptops take longer, and images over about 120 megapixels are declined rather than risking a frozen browser.
| Format | Where it opens | Typical use |
|---|---|---|
| AVIF | Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+ | High-quality web images where file size matters most |
| JPG | Every browser, app and device | Photographs and images with many colours |
| This converter | Current Chrome, Edge, Firefox and Safari. Needs JavaScript and WebAssembly | Private conversion on your own device |
AVIF is a newer format. Current browsers support it, but many older editors, operating systems and upload forms do not yet, so converting to JPG is the easiest fix.
Slightly, since JPG compresses again. At quality 90 or above the difference is hard to see. For a lossless copy use the AVIF to PNG Converter Online.
JPG cannot store it, so transparent pixels are blended with your chosen background colour. Choose PNG instead if you need to keep transparency.
AVIF is designed to compress better than JPG, so the same picture normally needs more bytes as a JPG.
Yes. When a browser cannot decode AVIF natively, the converter loads a built-in decoder so the file can still be read.
Yes, with the JPG to AVIF Converter Online, which gives the smaller modern format again.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. You can convert up to 50 AVIF files in one go. It is provided by Websolindia.
No. Your AVIF files are read and converted inside your browser, on your own device. They are never sent to Websolindia or anyone else, which is why this converter is safe for private photos and documents.
Yes. The new file is created from the decoded pixels, so camera details, GPS location and other embedded metadata are not copied. If you need to keep metadata, use a desktop editor.
Up to 50 files per batch and 150 MB per file. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari. It also needs WebAssembly, which all of those browsers include.
