How do I convert JPEG to AVIF?

Upload your JPEG file using the box above, confirm AVIF as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting JPG to AVIF free?

Yes, and there is nothing to sign up for. Every conversion route is free on every plan — paying raises limits such as file size and how many conversions you get, and removes advertising. It never unlocks a format, adds a watermark or degrades the output.

Will the quality change when converting to AVIF?

AVIF uses lossy compression, so some data is discarded to keep the file small. The default quality setting is tuned to be visually or audibly transparent for most material, and you can raise it in the conversion settings.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.

About JPG and AVIF

JPEG .jpg

The photographic standard since 1992. JPEG throws away detail your eye is least likely to miss, which is why a photograph saved as JPEG is a fraction of the size of the same image saved losslessly.

Good for

Opens everywhere — no format is more widely supported
Very small files for photographs and other continuous-tone images
A quality dial, so you choose the trade against file size

Trade-offs

Lossy: detail is discarded permanently, and re-saving repeatedly compounds it
No transparency at all
Sharp edges, flat colour and text pick up visible halos

image/jpeg

AVIF .avif

A modern image format derived from the AV1 video codec. It compresses harder than JPEG or WebP at the same visual quality, and handles wide colour and high dynamic range.

Good for

The smallest files of any format here at a given quality
Transparency, animation, wide colour gamut and HDR
Holds up better than JPEG at very low bitrates

Trade-offs

Support is newest — older browsers and many desktop apps cannot open it
Encoding is slow compared with JPEG
Fine detail can smooth over at aggressive settings

What changes when you convert JPG to AVIF

You choose how much to keep

AVIF can compress either lossily or losslessly, so the quality setting decides the outcome rather than the format. High quality stays close to the JPG you started with; lower settings trade visible detail for a much smaller file.

Encoding takes longer

AVIF comes from the AV1 video codec, and that compression is slow — noticeably slower than writing a JPEG or a PNG. The payoff is the smallest file of any format here at a comparable quality. Check your audience first: browsers handle AVIF well now, but plenty of desktop and print software still will not open it.

Camera data is removed by default

A JPG straight from a phone or camera carries EXIF metadata — model, settings, timestamp and, quite often, the GPS coordinates of where the photo was taken. The converted AVIF is written without it, so a file you are about to share does not quietly carry your location. The orientation flag is read and applied to the pixels first, so the image will not come out sideways once the tag holding it is gone. If you need the metadata kept, there is a setting for it.

How the AVIF is written

Our default is quality 60 — the scale is not comparable with JPEG's, and 60 here is a visually higher setting than the number suggests. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.
