JPG to AVIF: the biggest savings for web photos

If you're trying to speed up a website, images are usually the first place to look, and AVIF is one of the most efficient formats available. This JPG to AVIF converter re-encodes your photos with an AV1-based encoder, which can often cut the file in half compared with JPG at a similar visual quality.

On a photo-heavy page, that can trim megabytes. Visitors on slow mobile networks see the images sooner, and the page uses less of their data.

How to convert JPG to AVIF

You don't need any plugin or command-line tool. Encoding happens on your device.

  1. 1

    Queue your JPGs

    Add up to 20 photos by dragging them in or clicking the upload area.

  2. 2

    Pick an AVIF quality

    AVIF holds up well at lower numbers. Begin around 60 to 70 for website photos, and judge the result by eye.

  3. 3

    Be patient while it encodes

    AVIF takes longer to encode than JPG or WEBP. Large photos may need several seconds each, more on phones.

  4. 4

    Compare and download

    Result cards show how many bytes you saved. Download what you like, singly or zipped.

Quality settings work differently in AVIF

A quality of 90 in AVIF is much higher than most people need. Because the codec is so efficient, numbers that would look rough in JPG still look clean here. Use this as a starting guide:

AVIF qualityResultUse for
75–90Excellent, but with smaller savingsPortfolios and hero images
55–75Very good, with big savingsMost website photos
35–55Soft in fine detailThumbnails and background images

Using AVIF on a real site

  • Keep your JPG master. AVIF is for delivery. Store the original for future edits and other uses.
  • Resize before converting. Match the largest size you actually show, using Resize Image, so you aren't compressing pixels nobody will see.
  • Provide a fallback if needed. A picture element can offer AVIF first and JPG or WEBP second.
  • Check your CMS. Recent WordPress versions accept AVIF uploads if the server supports it. On other platforms, test one image first.

Prefer something quicker, with wider tool support? JPG to WEBP is a solid alternative. To reverse this conversion, use AVIF to JPG.

Private by default

Your photos are encoded in your own browser and never uploaded. There's no sign-up or watermark. Each photo can be up to 250 MB, though very large images take time to encode, and they're easier on a desktop than on a phone.

Every tool is free, private and runs in seconds.

Frequently asked questions

Often around 50%, and sometimes more for smooth images. The exact saving depends on the photo and the quality you choose, so try a few settings.
Yes. Chrome, Edge, Firefox and Safari 16 and later all display it. If you need to support older browsers, use the HTML picture element with a JPG or WEBP fallback.
Its compression, derived from the AV1 video codec, searches much harder for savings. That effort makes files smaller, but it costs time during encoding. Viewing the finished image isn't slow.
At sensible settings it should look the same at normal viewing size. Fine texture can look smoother at very low quality, so check faces and fabric at 100% zoom.
AVIF usually makes smaller files. WEBP encodes faster and is supported by more software. For a website with a fallback in place, AVIF gives the biggest savings; WEBP is the simpler option.
It's better not to. Many apps and older phones can't open AVIF. It's a publishing format for websites, so share the JPG instead.
No. The AVIF encoder runs in your browser, which is also why encoding speed depends on your own device.
