Why use this tool

Right size for pages

Serve images at the width they appear instead of shipping an oversized file and letting the browser scale it down.

Stays WebP

Output remains WebP, so you keep its compact files and transparency support without converting back and forth.

Batch an asset folder

Resize up to 200 WebP files in one pass and download them together as a ZIP.

Use cases

Responsive image sets

Create 480, 960 and 1440 px versions of the same WebP for a srcset, so phones download a smaller file than desktops.

Exported banners

Shrink a WebP banner exported from a design tool to the exact width your site template uses, without converting it to another format.

Store product images

Resize a set of WebP product shots to one consistent size so catalog pages load quickly and the images line up.

Technical details

WebP supports lossy and lossless compression plus transparency, which is why it's widely used for web delivery. This tool keeps the output in WebP and keeps transparent areas transparent. Dimensions matter more than format for page weight: a 4000 px wide WebP displayed in an 800 px column still makes visitors download 25 times more pixels than they actually see.

Current Chrome, Edge, Firefox and Safari all display WebP. If you need a copy for older software that doesn't, the general image resizer can save the same size as JPG or PNG. Resized WebP files are converted to sRGB and don't keep EXIF metadata such as camera or GPS details, which also trims a few bytes from every file. Keep your full-size originals, since a downsized WebP can't be scaled back up without losing sharpness.

Your files stay with you

This tool runs entirely inside your browser using Web Workers and WebAssembly. Your images are never uploaded, never stored on a server and never used to train AI. Close the tab and they’re gone. Learn more

Frequently asked questions

Will resizing keep my WebP transparent?

Yes. Output stays WebP, which supports an alpha channel, so transparent backgrounds and soft edges remain transparent. That makes it suitable for logos and product cut-outs placed over colored page sections.

What size should WebP images be for a website?

Match the largest size the image is displayed at, multiplied by two if you want it sharp on high-density screens. For a 700 px blog column, 1400 px wide is a common choice. Anything larger adds bytes that visitors never see.

Can I resize WebP without converting it to JPG or PNG?

Yes. This page reads WebP and writes WebP. You only change the dimensions, so there's no need to convert, resize and convert back, which would re-encode the image more times than necessary.

Do all browsers support WebP?

Current versions of Chrome, Edge, Firefox and Safari display WebP on desktop and mobile. Some older desktop programs and email clients may still not open it, so for those destinations JPG or PNG is the safer choice.

Is resizing WebP files in the browser private?

Yes. The images are decoded, resized and encoded inside your tab using Web Workers and Canvas. Nothing is sent to a server, which matters when the files are unreleased product shots or client work.
