À propos de cet outil
Convert AVIF images into JPG, PNG or WebP without uploading anything. AVIF is a modern format that compresses far better than JPEG, which is why sites use it - and also why plenty of older apps, printers and platforms still cannot open one. This tool decodes AVIF with your browser own engine and re-encodes it to the format you need, in batch, with a quality slider and a size comparison for every file. Because AVIF supports transparency and JPG does not, it also detects transparent areas and lets you choose the colour they are flattened onto rather than silently turning them black.
Transformer une photo iPhone ou AVIF en quelque chose que tout le monde peut ouvrir
Les formats d'appareil photo modernes sont efficaces mais de nombreuses applications ne peuvent pas les lire. Convertissez, puis ajustez la taille selon la destination.

Comment utiliser cet outil
- Add your AVIF filesClick or drop one or many .avif images. Everything is decoded on your device - nothing is uploaded.
- Choose the outputJPG for the smallest, most compatible file; PNG or WebP when the image has transparency you need to keep.
- DownloadSave images one by one, or grab the whole batch as a ZIP.
Pourquoi l’utiliser
- Batch conversion - drop a folder of AVIF files and convert them all in one pass.
- Quality slider, so you decide the trade-off instead of accepting a fixed setting.
- Transparency is handled honestly: JPG flattening uses a background colour you pick, and the tool tells you when it happened.
- Before and after file sizes for every image, plus a total for the batch.
- Runs entirely in your browser - no upload, no account, no watermark.
- Tells you up front if your browser cannot decode AVIF, rather than failing silently.
Usages courants
- Opening an AVIF you were sent when your software does not support the format.
- Converting AVIF product photos for a shop platform that only accepts JPG.
- Preparing AVIF screenshots for a document or presentation tool.
- Turning AVIF images into PNG so transparency survives for a design file.
- Batch converting a folder of AVIF exports before handing them to a client.
- Making an AVIF usable in older software that predates the format.
Conseils pour de meilleurs résultats
- Quality 90 to 95 is visually indistinguishable from the original for most photos.
- If the image has transparency, pick PNG or WebP - JPG cannot store an alpha channel.
- Set the background colour before converting to JPG if white is not what you want behind transparent areas.
- Converting to JPG usually makes the file BIGGER, because AVIF compresses better than JPEG.
- Use the ZIP download when converting more than a couple of images.
- Changing the output format re-converts the images already loaded - no need to add them again.
Erreurs à éviter
- Expecting the JPG to be smaller than the AVIF. AVIF is a newer, more efficient codec, so the opposite is normal.
- Converting to JPG and then wondering where the transparency went - use PNG or WebP instead.
- Using an old browser and assuming the tool is broken; AVIF decoding needs Chrome 85+, Firefox 93+ or Safari 16.4+.
- Re-converting an already-converted JPG expecting quality to improve - each lossy pass only loses more.
- Renaming a file to .avif and expecting it to convert; the contents have to actually be AVIF.
Questions fréquentes
Drop the .avif file onto the page, choose your JPEG quality and download the converted image. The conversion runs in your browser using its built-in AVIF decoder, so the file is never uploaded and there is no size limit beyond what your device can hold in memory. You can convert several files in one pass rather than repeating the process for each.
AVIF is a newer format that browsers adopted well before desktop software did. Chrome, Edge, Firefox and Safari all display it, but older versions of Windows Photos, Photoshop and most printing or print-on-demand services still reject it, which is the usual reason people need a JPG. Converting to JPG trades some file size for compatibility that works everywhere.
Drop your .avif files onto the page, leave the output set to JPG, and download the results. The conversion runs in your browser using its own AVIF decoder, so the images never leave your device.
Because AVIF is a much more efficient codec than JPEG. An AVIF at a given visual quality is routinely half the size of the equivalent JPG, so converting to JPG almost always increases the file size. That is expected, not a fault - you are trading size for compatibility.
AVIF supports an alpha channel and JPG does not. When you convert to JPG, transparent areas are filled with the background colour you pick, and the tool tells you when that has happened. Choose PNG or WebP to keep transparency intact.
Yes. Drop as many as you like - they are converted one after another with a progress count, and you can download them individually or all together as a ZIP.
No. Decoding and encoding both happen in your browser, so the files stay on your device. Nothing is sent to a server and nothing is stored.
The tool relies on the browser to decode AVIF, and older browsers have no decoder for it. Chrome 85+, Firefox 93+, Edge 121+ and Safari 16.4+ all work. The check runs when the page loads so you find out before wasting time on a drop that cannot succeed.
