How to Use Image to AVIF

1. 01

   Choose your images

   Choose Select images, or drop images into the panel. Add up to 50 still JPEG, PNG, WebP, SVG, or HEIC/HEIF files, up to 50 MB each. AVIF, APNG, GIF, animated images, and PDF files are not supported.

   Wait for the previews to open. Conversion starts when you download, so you can arrange or rotate your images first.

2. 02

   Arrange the images

   Drag a card to a new position. The numbered order is also used in the ZIP file.

   

3. 03

   Rotate if needed

   The curved arrow on a card rotates the image clockwise by 90°. Check its preview before saving. Raster images keep their pixel dimensions; SVGs are converted to pixels. Rotating by 90° or 270° swaps width and height.

   AVIF preserves transparent areas. The output is lossless, but it does not restore detail missing from the original. There are no quality or size settings to adjust.

4. 04

   Convert and save

   Use Download or Download ZIP at the right end of the toolbar.

   One image saves as an AVIF; multiple images save together in a ZIP. A card’s download arrow converts and saves only that image. Wait for conversion and the browser download to finish.

   After conversion, each card shows the original and AVIF file sizes. An AVIF can be larger than the source image.

   

5. 05

   Add, replace, or remove images

   Use + or Add images to append images. The replacement icon changes one image in the same position and resets that image’s rotation.

   Use × on a card to remove it. The trash icon removes all images after confirmation; you can then add another batch. Your original files remain on your device.
