How to compress an image

- Set a target size Use the preset or enter your own limit in kilobytes.
- Download the result The tool returns the best quality that fits under the limit.
Why compress a WebP?
WebP typically produces smaller files than JPG at similar quality, but that does not make it automatically small. A high-resolution product photo exported as WebP can still be 1–3MB. If a CMS, marketplace, or email client has a cap, you still need a target-size pass.
Compressing an already-lossy WebP is a second generation of loss. Start from the original when possible, and compress only the copy that will be published.
Transparency and browser support
WebP supports alpha transparency, so logos and cut-out images keep their transparent background. All current versions of Chrome, Edge, Firefox, and Safari can display WebP. Older software, some email clients, and a few upload systems may still reject it; in that case convert to JPG or PNG.
A good workflow for web images
- Resize to the largest size the page actually displays, not the camera resolution.
- Use a target around 100–300KB for content images.
- Keep a high-quality original outside the project folder.
- Use lazy loading and responsive image sizes on the page itself.
Frequently asked questions
Does compressing WebP reduce quality?
Yes, WebP can be lossy. The tool finds the highest quality that fits your target, but repeated compression will gradually soften the image.
Can I keep transparency?
Yes. Choose WebP output and transparent areas remain transparent. Choosing JPG will flatten them to white.
Will the WebP still work in Safari?
Current Safari versions support WebP. If you need to support very old browsers or an app that does not accept WebP, convert to JPG or PNG instead.
Can I compress WebP files in bulk?
Yes. Add multiple files, set one target, and download the successful results as a ZIP.
