Tool guide
How to use the Image Compressor
Choose an image, set its output width and height, select JPG or WebP, then process and download the result. Compression runs in your browser, so the image is not uploaded to a server.
What this tool is useful for
- Prepare smaller product photos for a website.
- Reduce the size of an image before emailing it.
- Compare WebP and JPG output for the same photo.
Practical example
For a 2400 × 1600 photo, try 1200 × 800 with WebP output and quality 0.8. Process the image, inspect small details and text in the preview, then download it and check the saved file size. The reduction depends on the original image; no fixed percentage is guaranteed.
Helpful tips
- Keep the width and height in the original proportion to avoid stretching.
- Quality affects JPG and WebP output; lowering it does not provide the same control for PNG.
- JPG replaces transparent areas with white. Use PNG or WebP when transparency matters.
- Compare the downloaded file with the original: re-encoding can sometimes increase file size.
