WebP Compressor – Reduce WebP File Size Online
Shrink your WebP images further with a quality slider you control — transparency stays intact, and everything runs in your browser.

Lower quality = smaller file size. PNGs reduce the color palette for a real size cut (best on photos without transparency); JPG/WebP/AVIF use standard lossy compression.
About This Tool
WebP is already an efficient format, but that doesn’t mean every
WebP file is as small as it could be — many are exported at a
higher quality than a website actually needs. This tool
re-compresses your WebP images with a quality slider you control,
and unlike JPEG, transparency is fully preserved throughout. Drop
your files in and compression starts immediately, with a live
preview so you can see the result before you download anything.
Key Features
Instant Compression
No upload step and no button to click — compression starts
the moment you add an image.
Private & Secure
Your files never leave your device — nothing is ever uploaded to a server.
Batch Processing
Compress a handful of images or hundreds at once — there’s no batch limit.
Transparency Preserved
Unlike JPEG, WebP supports transparency — and it stays fully intact through compression.
Works Everywhere
Compatible with desktop, tablet, and mobile browsers — no app to install.
Completely Free
No subscriptions, registrations, sign-ups, or hidden limits.
How It Works

Fine-Tune If You Want
Drag the quality slider and every image recompresses live with a fresh preview and new file size.

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up and no limit on how many images you compress.
Are my images uploaded to a server?
No. Every image is compressed locally in your own browser and never leaves your device.
Isn’t WebP already compressed? Why compress it again?
WebP is efficient, but plenty of files are exported at a
higher quality setting than they need for the web. Dialing
the quality down here can still shrink an already-WebP file
meaningfully, especially for background images and large
photos.
What happens to transparency in my WebP image?
It’s preserved. WebP supports an alpha channel the same way
PNG does, and compressing here keeps that transparency
intact — nothing gets flattened to a solid background.
What if my WebP doesn’t get any smaller?
Some WebP files are already tightly compressed. If
recompressing wouldn’t actually reduce the file size, the
tool keeps your original file rather than replacing it with
a larger one.
Can I compress multiple WebP images at once?
Yes — drop in as many as you like and each one compresses automatically, with no batch limit.
