To compress a WebP image online, add your WebP files above, set a quality (about 70 to 80 suits most images) or tick Lossless, then press Compress. Free, private, and your images are never uploaded.
Add your images, choose the settings and download smaller files. Everything runs in your browser, so your images are never uploaded.
Loading the tool…
To compress a WebP image online, add your WebP files above, set a quality (about 70 to 80 suits most images) or tick Lossless, then press Compress. The files are re-encoded with libwebp in your browser. Nothing is uploaded, and if the result is not smaller you keep your original.
Squeeze WebP images even smaller. Re-encode them at a lower quality for the biggest saving, or use lossless mode to keep pixels identical, with transparency preserved either way. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online image tools, this one does not upload your pictures. Your browser decodes each image, re-encodes it with an open-source compression engine and shows you the exact before and after sizes. You can process up to 30 images at a time and download them one by one or together as a ZIP.
Once your image is ready, you may also want the AVIF Image Compressor Online, the JPG Image Compressor Online or the JPG to WebP Converter Online. All of our free image tools are listed in the Image Compressor Tools collection and the Websolindia Image Converter.
Use this table to choose settings with confidence.
| Quality | Result | Typical use |
|---|---|---|
| 90–100 | Very high quality, larger files | Archives, detailed graphics |
| 75–89 | High quality (recommended) | Websites, product photos |
| 60–74 | Good quality, smaller files | Thumbnails, galleries |
| Below 60 | Visible softening | Smallest files only |
| Lossless | Identical pixels | Logos, UI graphics |
This is exactly what happens to your image, with no hidden step. You can check that nothing is uploaded by watching your browser's network tab while you use the tool.
| Step | What happens |
|---|---|
| 1. Read and decode | The WebP is decoded to pixels by your browser. |
| 2. Resize (optional) | A maximum width scales larger images down; images are never enlarged. |
| 3. Encode with libwebp | The pixels are encoded as WebP at your quality, or losslessly, by your browser's encoder or by libwebp compiled to WebAssembly. |
| 4. Compare with the original | If the new file is not smaller than your original, we return your original instead. |
| Setting | Default | Choices | What it does |
|---|---|---|---|
| Quality | 75 | 1 to 100 | 70–80 suits most images. |
| Lossless (identical pixels, larger) | Off | On / Off | |
| Maximum width in pixels (optional) | Empty | 1 to 20000 | Larger images are scaled down, never up. |
| What | Formula | Notes |
|---|---|---|
| Size change | (new − original) ÷ original × 100 | Shown for every file. |
| Quality | Integer 1–100 passed to libwebp | Ignored in lossless mode. |
| Component | Role | Where it runs |
|---|---|---|
| libwebp | Encodes WebP (browser encoder or WebAssembly) | Your browser |
| Topic | Detail |
|---|---|
| Images per batch | Up to 30 at a time |
| File size | Up to 150 MB per image |
| Image dimensions | Up to about 120 megapixels; larger images are declined to protect your browser |
| Privacy | Images are processed in your browser and never uploaded |
| Browsers | Current Chrome, Edge, Firefox and Safari (WebAssembly is needed for AVIF, HEIC, TIFF and AI tools) |
| Metadata | EXIF and location data are not copied into new files |
Both are available. Lossy trades some detail for a much smaller file; lossless keeps every pixel. The tool offers both.
It depends on the image and quality. Google reports lossy WebP is typically 25 to 34 percent smaller than comparable JPEG and lossless WebP about 26 percent smaller than PNG; recompressing an existing WebP saves less.
Yes, in both lossy and lossless modes.
If it was already well compressed, our result was not smaller, so your original is returned unchanged.
AVIF is often smaller still but slower to encode and less widely supported. Try the AVIF Image Compressor Online and keep a WebP or JPG fallback.
Yes: the WebP to JPG Converter Online and the WebP to PNG Converter Online convert WebP for software that does not support it.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. It is provided by Websolindia.
No. Your images are read and processed inside your browser on your own device. They are never sent to Websolindia or anyone else, which is why the tool is safe for private photos.
No. New files are created from the pixels, so camera details, GPS location and other embedded metadata are not copied. Keep your originals if you need that information.
Up to 30 images per batch and 150 MB per image. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari on computers, phones and tablets. Large images and AI or AVIF features run faster on a computer.
