Resize WEBP

Resize WEBP images online and free: type a width or a height in pixels, centimeters, millimeters or inches, and save. A WebP keeps its transparency, so logos and cut-outs stay clean. Nothing is uploaded: your browser does the work.

How to resize WEBP images

  1. 1Drop your images in, or click to choose them
  2. 2Type a width, a height, or both, and pick the unit
  3. 3Press "Convert" and save the result
  4. Resized images, as WEBP 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 WEBP 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 WebP.
  • Scale a batch of WebP files for a site, for example all to 1600 pixels wide, and get them as one ZIP.

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.
  • Resizing a WebP re-encodes it, so each pass costs a little quality.

Questions

How do I resize a WebP 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. A WebP 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.
