AVIF to WebP Converter

Drop a AVIF, get a WebP. Nothing is uploaded.

Lower makes a smaller file and softens fine detail. 0.92 is what most tools use when they do not ask.

Resize

The shape is always kept, so the other side follows. Neither maximum ever ENLARGES a picture that is already smaller than it.

Pixels for either maximum, and a percentage for the last one. It is ignored while Resize is keeping the original size.

Nothing is uploaded. Your file is read in your browser and never leaves your computer.

What this does

A recent phone, a photo editor’s export dialogue and most large websites now save their pictures as AVIF. A WebP is usually a third smaller than the same picture as a PNG or a JPG, which is why a website wants one. It turns up when a modern site or a new phone saves a picture at its smallest, and then an older program refuses to open it.

How it works

  1. Choose your AVIF fileDrag a AVIF file onto the box above, or press it and pick one. It is read in your browser, so nothing is uploaded.
  2. Wait for the WebPThe conversion runs on your own computer, so how long it takes depends on your machine and the size of the file, not on a queue.
  3. Download the WebPPress the download button. The WebP file lands in your downloads folder, ready for your slicer.

About the formats

Why your file is a AVIF
AV1 Image File Format. A recent phone, a photo editor’s export dialogue and most large websites now save their pictures as AVIF.
Why you want a WebP
WebP. A WebP is usually a third smaller than the same picture as a PNG or a JPG, which is why a website wants one.
What a WebP holds
Either exact pixels or compressed ones, with transparency either way, in fewer bytes than both.
What changes on the way to WebP
The whole picture comes through, transparency and all, and the result sits between the two: well under a PNG, comfortably over the AVIF it started as.
Where this format turns up
It turns up when a modern site or a new phone saves a picture at its smallest, and then an older program refuses to open it.

Questions

Is AVIF to WebP Converter free?

Yes. Every tool on Short Work Tools is free, with no account, no sign-in and no limit on how many files you run through it. It runs on your own computer, so it costs us nothing to give away.

Is my file uploaded anywhere?

No. Nothing is uploaded. Your file is read in your browser and never leaves your computer. There is no upload step, no server copy and nothing kept afterwards, which is also why it works with the network switched off once the page has loaded.

What does the WebP keep from the AVIF?

Either exact pixels or compressed ones, with transparency either way, in fewer bytes than both. The whole picture comes through, transparency and all, and the result sits between the two: well under a PNG, comfortably over the AVIF it started as.

How large a file can I use?

Up to 250 MB. The limit is your browser's memory rather than an upload size, because the file never goes anywhere; a file larger than that is refused with a message rather than crashing the tab.

Which programs write AVIF files?

A recent phone, a photo editor’s export dialogue and most large websites now save their pictures as AVIF. It turns up when a modern site or a new phone saves a picture at its smallest, and then an older program refuses to open it.

Does the converted picture keep the information the camera wrote into it?

No, and there is no setting for it because there is nothing to set. The picture is decoded to pixels and drawn onto a fresh canvas, and a canvas has no place to put the camera model, the date or the GPS position the original carried, so none of it is in the file you get back.
