How to compress a WebP in 3 steps

Drop your WebP files into the box above, or click to browse. Riducly compresses each one instantly in your browser. Then download the optimized images one by one, or all at once as a ZIP.

Why compress WebP at all

WebP is already an efficient modern format, but exports from design and conversion tools often use conservative settings that leave size on the table. Re-encoding at an optimized quality squeezes out the extra weight while keeping the image visually identical — ideal for faster-loading websites.

Lossy and lossless WebP

WebP supports both lossy compression (smaller files, like JPG) and lossless (pixel-perfect, like PNG), including transparency. Riducly keeps your WebP as WebP at an efficient quality, so you get the format's full size advantage without changing what it can do.

WebP vs JPG and PNG

WebP typically produces smaller files than both JPG and PNG at similar quality, with support for transparency and modern browsers. Keep JPG or PNG when you need maximum compatibility with older software or email. Riducly can compress or convert between all of them from the same tool.

Frequently asked questions

Does compressing a WebP reduce its quality?
Riducly re-encodes WebP at a balanced quality where the change stays invisible at normal viewing size. You get a smaller file that looks the same; lossless WebP stays pixel-for-pixel identical.
Are my files uploaded to a server?
No. Riducly compresses images entirely in your browser, using your device's own processor. Your files never leave your computer, which keeps the tool private and fast.
Do WebP images keep transparency after compression?
Yes. Riducly preserves the alpha (transparency) channel, so WebP images with transparent backgrounds stay transparent.
Why is WebP smaller than JPG or PNG?
WebP uses more advanced compression than JPG and PNG, so it reaches similar quality with fewer bytes — and it supports both transparency and animation. That makes it a strong default for the web.
Is there a limit to how many WebP files I can compress?
You can compress multiple files at once for free. Creating a free account unlocks higher limits and parallel, multi-core compression for larger batches.
