Resize WEBP Images Online
Change the pixel size of any WEBP image in your browser. Pick a percentage, a target width, an exact size or a social preset, then download the resized file.
How to Resize a WEBP Image
Three steps, no upload queue and no sign-up. Everything runs locally in your browser, so your images never leave your device before or after resizing.
Step 1
Upload your WEBP files
Drop one or more WEBP files into the box, or browse. Files up to 20 MB are accepted.
Step 2
Choose a resize mode
Scale by percentage, set a target width, type exact dimensions, or pick a ready-made social preset.
Step 3
Pick WEBP and download
Set Output Format to WEBP, adjust quality if needed, then resize and download your files.
Why Use This WEBP Resizer for Everyday Image Resizing Work
WEBP delivers modern compression, but the file you have is rarely the size you need. A hero banner may have to drop from 2560 pixels to 1280, a marketplace listing may demand an exact 1080 by 1080 square, and an email header may need to stay under a strict width. Re-encoding by hand usually means opening a desktop editor, exporting, checking the result and repeating the process for every single file. This resizer removes those steps: you drop your WEBP images in, choose how the new size should be calculated, and download the results a moment later.
Four resize modes cover almost every real request. By Percentage scales an image anywhere from 1 to 200 percent, which is the fastest way to halve a screenshot or enlarge a small icon. By Width keeps the aspect ratio and simply asks for the target width in pixels, so you never have to calculate the matching height yourself. Exact Width and Height lets you type both numbers and decide whether to preserve the ratio or fill the canvas, with a background colour covering any empty space. Preset Sizes holds ready-made dimensions for Instagram squares and portraits, Facebook covers and share cards, Twitter headers, YouTube thumbnails and HD wallpapers.
Output control matters as much as the geometry. The Output Format selector defaults to Keep Original, so set it to WEBP when you want the resized file to stay in the same compact format your site already serves. A quality slider from 10 to 100 controls the re-encoding level, bearing in mind that quality only affects JPEG and WEBP output because PNG is always lossless. You can load several images in one go and collect everything in a single ZIP archive, which turns a folder of oversized product shots into a consistent set in one pass.
Everything happens on your own device. Your images are decoded, resized and re-encoded in the browser canvas, so nothing is uploaded, queued, stored or analysed by a remote server, and there is no watermark, no daily quota and no sign-up wall. That also means the tool keeps working at your own pace: resize one screenshot or a couple of hundred catalogue images, then close the tab and the files are gone. If you need a different size afterwards, reload the page and run the images through again with new numbers.
One thing worth knowing about WEBP: because resizing re-encodes the image, saving a WEBP back to WEBP at a lower quality discards a little detail each time. When the source is already a WEBP you plan to keep editing, start from the original file and export only once at the end of the workflow.
Four Resize Modes
Scale by percentage, match a target width, enter exact dimensions, or apply a ready-made social preset.
Keeps WEBP Output
Select WEBP as the output format and the resized file stays in the same modern, compact format.
Batch Friendly
Load several images at once, resize them together and grab everything in a single ZIP archive.
Quality Control
A quality slider from 10 to 100 lets you trade a little detail for a much smaller file.
Nothing Leaves Device
Resizing happens entirely in your browser, so private photos are never uploaded anywhere.
No Sign-Up Needed
Open the page, drop an image and download the result without creating an account or installing software.
FAQ
Frequently Asked Questions
Resizing always re-encodes the picture, so some detail changes. Keep the quality slider high, around 90 to 100, and the difference is rarely visible. Quality only applies to JPEG and WEBP output, since PNG stays lossless.
Yes, in By Width and By Percentage modes the ratio is always preserved. In Exact Width and Height mode you decide: leave Maintain Aspect Ratio checked to keep the ratio, or uncheck it and fill the extra space with a colour.
Each image can be up to 20 MB. Very large panoramas or print-resolution scans beyond that limit should be downscaled once in a desktop editor before being uploaded to the resizer.
Yes. The file picker accepts multiple images, every file is processed with the same mode and settings, and the Download All button collects the finished results into one ZIP archive.
Use Preset Sizes and pick Instagram Square for a 1080 by 1080 post or Instagram Portrait for a 1080 by 1350 post. Both presets can keep the aspect ratio and pad the remaining space with a colour you choose.
Only if you ask for it. Output Format defaults to Keep Original, which simply keeps whatever format you uploaded. Change it to WEBP when you want the resized copy explicitly re-encoded as WEBP.
No. Canvas encoding applies a quality value only to JPEG and WEBP, so PNG files are written losslessly no matter where the slider sits. Switch to WEBP or JPEG if you want the slider to change the file size.
No. Resized files are delivered exactly as the canvas produced them, with no watermark, no logo and no added border, and the download keeps a clean filename you can rename as you like.
Nothing at all. The resizer is a pure front-end tool that runs in a modern browser, so there is no plugin, no desktop application, no account and no email address required at any point.
Transparency is preserved when you export to WEBP or PNG. If you choose JPEG, or use Exact mode unchecked with padding, the transparent areas are flattened onto the background colour you picked in the settings.
