How do you convert JPG to AVIF?

How do you convert JPG to AVIF?

Drop your JPG file on the page, or pick it from your device, and it is ready to convert at once. Press the button and your AVIF comes back to download in seconds, one file for a single image or a zip for a set. A single image is rebuilt right on the page, an AVIF is encoded on our server with an in-browser fallback. Nothing is set up beforehand.

Why convert JPG to AVIF?

Why convert JPG to AVIF?

AVIF is the most efficient image format in wide use, often landing well under half the size of a JPG at a quality your eye cannot tell apart. Converting a JPG to AVIF is how you make a photo as light as it can be for a fast website or a tight storage budget, when you know the place it is going can read AVIF.

What changes when you go from JPG to AVIF

What changes when you go from JPG to AVIF

The photo looks the same at a far smaller size, which is the whole point. The thing to weigh is support: AVIF is read by current browsers but not by every old app, printer, or piece of software, so use it where you control the destination, and keep a JPG or WebP for anywhere that might reject it.

Will AVIF open where you need it?

Will AVIF open where you need it?

AVIF is read by current browsers but not by every older app, printer, or tool, so the safe move is to use it where you control the destination and keep a more universal format around for anywhere that might still reject it. That is the one trade-off worth weighing before you commit a whole library to AVIF.

What happens to your images

What happens to your images

An AVIF is encoded on our server for the best squeeze, with a fallback on the page if the server is offline, so a single one may be uploaded, and converting several at once goes to the server too. Either way the download link is removed within about two hours, and a button deletes it the moment you have your file, so nothing is kept around. You can open the network panel to see exactly which path ran for your image.

When another tool fits better

When another tool fits better

This converter changes the format and keeps the picture. If the AVIF is still heavier than you want, run it through a compressor, and if it is larger on screen than it needs to be, set its size with a resizer first. To go the other way, convert AVIF back to JPG.

How it works

  1. Add your image

    Drop your JPG on the page or pick it from your device, one or a whole set.

  2. Press convert

    The tool rebuilds it as a AVIF, one file or a zip for several.

  3. Single or batch

    One image converts on the page, several use our server, link gone in ~2h.

  4. Download the AVIF

    Save your AVIF, or the zip, to your device.

Other tools to finish the job

Converting changes the format. Make the AVIF lighter, set its size, or convert it back to JPG.

Frequently asked questions

How do I convert JPG to AVIF for free?

Open the page, add your JPG with a click or a drag, and press convert. Your AVIF comes back ready to save in seconds, a single file or a zip for several, with nothing stamped on it and nothing to pay. There is nothing to install first.

Does converting JPG to AVIF lose quality?

The picture looks the same, and the AVIF is saved at high quality. AVIF holds the look at a far smaller size, and the only thing to weigh is where it will open, since it is the newest of the formats.

Does AVIF keep a transparent background?

Yes, AVIF supports transparency, so a see-through area in your JPG stays clear in the AVIF, with nothing flattened or filled in along the way. That is one of the main reasons to pick AVIF over a format like JPG, which would turn those clear areas white.

What happens to my image when I convert it?

Because the best AVIF squeeze is heavy work, the encode runs on our server, with a fallback on the page if it is unreachable, so even a single file may go up. Whatever the count, the result is handed back and the link expires within about two hours, sooner if you press delete. Nothing is held beyond that.

Can I convert several JPG files at once?

Yes, drop a whole set and they come back as a single zip you download in one go. A batch is the case that uses the server, so the files go up, get converted and zipped, and the link expires on its own within about two hours, sooner if you tap delete. It is the iLove-style batch flow, one press for the lot.

Is the JPG to AVIF converter really free?

Yes. The AVIF comes back with nothing stamped on it, no badge in the corner and no mark across it, and there is nothing to pay for the download. You save the file and use it wherever you need, as many times as you like.

The details

Notes from the team on craft, formats, and the small decisions behind a good round crop.

Why JPG to AVIF specifically
Each format earns its place, and the reason to make this exact switch is simple: a JPG becomes an AVIF that is dramatically smaller at the same quality. People reach for it when the JPG is technically fine but the situation in front of them wants a AVIF instead, an app that will not open the JPG, a page that loads faster, a tool that insists on one format. Picking the conversion by what the destination actually accepts, rather than by habit, is what saves a second round trip later.
One image stays on the page, several use the server
This converter leans on the server for AVIF, because the tightest encode is heavy work, a single AVIF is built on our server with an in-browser fallback, so it may upload. Converting several at once is heavier either way, so the images upload to our server, which converts and zips them and hands back one download from our CDN. That zip is removed within about two hours, and a button lets you delete it the instant you have it. If the server is ever busy or offline the tool quietly falls back to converting on the page, so you get your files regardless. The honest version is the useful one: a single non-AVIF image is kept to itself by staying put, and a batch is handled on a server that keeps nothing for long.
JPG and AVIF, what each format is good at
It helps to know why these two differ. JPG is lossy, small, and opens everywhere, but holds no transparency. AVIF is the smallest format in wide use and keeps transparency, but it is the newest. Converting JPG to AVIF trades one set of these properties for the other, so pick the direction by what the destination needs, smaller, more compatible, with no detail lost, or transparent. When the goal is a lighter file rather than a different format, a compressor is the better tool.
