Batch compress WebP photos with adjustable quality - entirely in your browser.
Drag the quality slider from 1 to 100 and dial in exactly the trade-off you want between file size and visual fidelity for your WebP images.
Cap the max width or height in pixels to shrink oversized photos before they're even compressed - great for web uploads and email attachments.
Compression runs on your browser's own Canvas engine. Your images are never sent to a server, so there's nothing to leak and no upload wait.
Drop in dozens of WebP files, apply the same quality and size settings to all of them, and download every result together in a single ZIP.
Drag the before/after slider on any compressed file to inspect quality loss side-by-side before committing.
Compress as many WebP images as you like - no watermark, no account, no catch.
Drag and drop .webp files, or click to browse from your device.
Adjust the quality slider and optionally cap the max width or height before compressing.
Grab each file individually, or all at once as a ZIP - no sign-up required.
WebP uses lossy compression - it discards some detail to shrink file size, and you control how much with the quality slider. Lowering quality keeps the same dimensions but adds visible compression artifacts; resizing instead reduces the actual pixel count.
Tip: quality 65–80 usually gives the smallest file with barely visible loss for photos. Combine a slight resize with a quality drop for the biggest savings on oversized images.
imgxcolor's WebP compressor shrinks .webp files directly in your browser - no software, no file uploads, no cost. Drop in one photo or a whole batch, tune the quality and size, and download the results in seconds.
It's built for anyone shipping photos to the web, attaching images to email, or just trying to free up storage without losing noticeable quality.
The quality slider controls how aggressively WebP compression discards detail at the same pixel dimensions. Resizing reduces the actual number of pixels in the image. Large photos benefit most from resizing first, then compressing; already-small photos usually only need a quality adjustment.
Every compression runs locally with JavaScript and the Canvas API. Your images are never uploaded, stored, or transmitted, which makes this compressor safe for client work, personal photos, or any image you'd rather not send to a third-party server. There are no accounts, no sign-ups, and no usage limits.
No. imgxcolor decodes and re-encodes every WebP image locally using your browser's Canvas engine, so nothing is ever uploaded and the result appears instantly.
The quality slider controls how much lossy compression is applied to each pixel. Lower quality settings add compression artifacts but reduce file size more aggressively.
Yes. You can resize by setting a maximum width or height, which reduces the total number of pixels. Combining quality reduction with resizing gives the biggest size reduction.
Yes. Drop in as many WebP files as you like, apply the same quality and size settings to the whole batch, compress them together, and download every result at once as a ZIP.
No hard limit - only what your device's memory can comfortably handle. The tool is free, has no watermark, and doesn't require an account.
