How it works

Resize WebP in 4 steps

  1. Drop a WebP file onto the tool or click Choose File.

  2. Set the exact width your layout needs - height follows the aspect lock.

  3. Preview updates live; sanity-check sharpness.

  4. Download the right-sized WebP.

When to use it

WebP earns its keep on the web, but only when it's served at the right dimensions - a 3000px WebP in a 600px slot wastes every byte it saved. Resize your WebP locally to the exact size each layout slot needs, with transparency preserved.

  • Cut oversized AI-generated WebP images down to layout size.
  • Produce 1x and 2x (retina) sizes for srcset from one master file.
  • Resize a batch of gallery images in one Pro run.

Format & quality notes

  • Serve images at roughly the pixels they display (2x for retina) - dimension is a bigger lever than quality.
  • Transparency is preserved; output stays WebP.
  • For srcset workflows, resize the same master at 1x and 2x rather than upscaling a small file.
FAQ

Questions about the Resize WebP.

What sizes should I generate for responsive images?

A practical set: the slot width at 1x and 2x (e.g. 600px and 1200px for a 600px column). More granular steps rarely pay for the effort.

Does resizing WebP lose quality?

Downscaling re-encodes at 92% quality, which is visually transparent. As with any format, upscaling past the original softens.

Transparent WebP - still transparent after?

Yes, the alpha channel survives resizing untouched.

Is my file uploaded?
