Resize AVIF
Resize AVIF images online and free: type a width or a height in pixels, centimeters, millimeters or inches, and save. AVIF is written with the tool's own encoder, so it works the same in every browser. Nothing is uploaded: your browser does the work.
How to resize AVIF images
- 1Drop your images in, or click to choose them
- 2Type a width, a height, or both, and pick the unit
- 3Press "Convert" and save the result
- Resized images, as AVIF unless you pick another format.
What happens to your files
- Nothing is uploaded.Your images are read and resized by your browser, on your own device.
- Ratio kept with one side.Fill in only the width or the height and the other follows.
- Many at once.Add a batch, set one size, and get one ZIP.
What you can do
- Fill in only the width or only the height, and the other side follows so the picture does not stretch. Fill in both and you get exactly that size.
- Choose the unit: Pixels, cm, mm or Inches. For cm, mm and inches you also set the DPI, which starts at 200.
- Under "Format" keep AVIF or save as PNG, JPG, WebP or AVIF in the same step.
- Set the quality, 30 to 100, starting at 85. A lower quality gives a smaller AVIF.
- Take an AVIF down to a smaller size, or save it as JPG or PNG if the place you upload to does not accept AVIF.
Good to know
- Percent is not offered: the size is a number of pixels, or a length with a DPI.
- If you fill in both sides, the picture is scaled to exactly that size and can look stretched when the ratio differs.
- Several files come back as one ZIP. JPG turns transparency white.
- AVIF takes longer to write than JPG, so a big batch can need a little time.
Questions
How do I resize a AVIF to a certain width?
Drop it in, type the width in the width field, leave the height empty and press "Convert". The height follows from the picture's ratio.
Can I set a size in centimeters?
Yes. Choose cm, mm or Inches as the unit and set the DPI. An AVIF has no DPI tag written, so the size is converted to pixels.
Can I resize many images at once?
Yes. Add them all, set one size, and you get one ZIP.
