About the Image Compressor
Reduce the file size of JPEG, PNG and WebP images directly in your browser, without uploading them to a server. Smaller images load faster, improve Core Web Vitals and save bandwidth on mobile. Adjust the quality level to balance size against visual fidelity, optionally resize the dimensions, and convert between formats. Your photos never leave your device, which makes this safe for private or client images.
How to use the Image Compressor
- Drop an image onto the upload area or click to select one.
- Choose the output format and quality level.
- Compare the original and compressed sizes.
- Download the optimised image.
Frequently asked questions
Which format should I choose?
WebP usually gives the smallest files with good quality. Use JPEG for photos when WebP is not supported, and PNG when you need transparency or crisp line art.
Will compression make my image blurry?
At quality 75–85 the difference is rarely visible. Go lower only for thumbnails or when size matters more than detail.
Is there a file size limit?
Processing happens in the browser, so very large images depend on your device memory, but typical photos of several megabytes work fine.
