82 is the point where most people stop being able to tell. Above 90 the file grows fast for very little.

Any CSS colour. Without one, transparency becomes black — which is what an empty canvas is.

  • No upload The conversion runs in this tab. Your file never travels — not to us, and not to the advertising.
  • No sign-up, no email, no daily cap There is no account system to sign up to.
  • No size limit we invented Only your device's memory — about ~2 GB on a desktop browser, ~400 MB on a phone.
  • Turn your Wi-Fi off and convert anyway The conversion needs nothing but this page. Ads will not load without a connection; your file will still convert. That is the whole claim, and it takes five seconds to check.

Converts AVIF to JPG. AVIF is the newest of the web image formats and by some distance the best compressor — which is also why so little desktop software opens it.

Why AVIF is everywhere and nowhere

AVIF uses AV1 video compression for still images. At low bitrates it comfortably beats WebP and JPEG, it supports transparency, HDR and wide colour gamut, and every current browser decodes it.

Outside the browser, support is thin. Windows needs an extension from the Store, older macOS cannot preview it, Photoshop needed a plugin until recently, and most upload forms reject it outright. That gap is why this conversion exists.

HDR and wide gamut are flattened

AVIF can carry high dynamic range and a wide colour gamut. JPEG carries neither: it is 8 bits per channel in a standard gamut.

When an HDR AVIF is converted, the browser tone-maps it down to sRGB. Bright highlights compress and very saturated colours shift slightly. For a normal photograph this is imperceptible; for a deliberately HDR image it is a real change, and there is no way around it in JPEG.

Transparency, and the black background problem

JPEG has no alpha channel. When a transparent PNG or WebP is converted, every transparent pixel has to become something.

The naive implementation draws the image onto a fresh canvas and encodes it. A fresh canvas is transparent black, so those pixels come out black — and "my logo has a black box around it" is the single most-reported bug in every image converter that exists.

Here the canvas is filled with your chosen background first, white by default. Set it to whatever the image will sit on: #ffffff for a page, #000000 for a dark one, or any CSS colour.

Metadata is removed, which is usually the point

Re-encoding through a canvas keeps the pixels and discards everything else: EXIF, GPS coordinates, camera make and model, lens, shutter speed, the timestamp, any embedded thumbnail, and the colour profile.

For a photo you are about to publish this is a feature. A JPEG straight off a phone can carry the exact coordinates of where it was taken, and stripping that before it goes anywhere public is good practice — the conversion does it as a side effect.

The one piece of metadata that is honoured before being dropped is the orientation flag. Phones store photos in the sensor's native orientation with a tag saying which way is up; ignoring it produces sideways pictures. It is applied to the pixels, so the result is upright without needing the tag.

If you need the EXIF preserved, this is the wrong tool — a converter that re-encodes cannot keep it.

Questions

Why will nothing open my AVIF file?
Browsers decode AVIF; most desktop software still does not. Windows needs an extension from the Store, and many upload forms reject the format entirely.
Will the file get bigger?
Usually substantially — AVIF compresses far better than JPEG. Two to four times larger at comparable quality is normal.
It says my AVIF could not be decoded.
Your browser may be too old, or the file uses a bit depth or feature it does not support. Try the newest version of Chrome, Edge or Firefox.
Can I convert a whole folder of images?
Yes. Drop as many files as you like, or a whole folder. Each keeps its original name with the new extension — IMG_4032.heic becomes IMG_4032.jpg, never converted_1.jpg — and you can download them individually or as a ZIP.
Are my photos uploaded?
No. The decoding and re-encoding happen in this tab using the browser’s own image support. Photos are personal in a way most files are not, and none of them is transmitted. Turn your Wi-Fi off and the converter keeps working.
How large an image can I convert?
The practical ceiling is the browser’s canvas limit, about 268 million pixels in total area — roughly 16,000 × 16,000. Above that you get a clear error rather than a silent failure, and resizing first is the fix. File size itself is limited only by your device’s memory.
