About the Image Compressor

Large image files slow down websites, fill up inboxes, and take longer to share. Our image compressor lets you reduce file sizes in seconds without sending anything to a server. Drag the quality slider to control the trade-off between file size and visual quality, optionally cap the maximum width to downscale the image, and choose JPEG or WebP for the smallest output.

The tool works with any browser-decodable image — JPEG, PNG, WebP, GIF, BMP and more. Once compressed, the tool shows you the original size, the new size, and the percentage saved so you can iterate until you're happy. All processing happens locally, making it safe to use with confidential photos or documents you wouldn't want to upload to a third-party service.

Frequently asked questions

Are my images uploaded to a server?

No. Compression runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device and no data is sent to any server.

What quality setting should I use?

For photos destined for the web, 60–80% typically gives a good balance between visual quality and file size. For images that need to look pristine, use 85–95%. Settings below 50% can introduce visible artefacts.

Can I compress PNG files?

Yes. Set the output format to JPEG or WebP for the best compression ratios — PNG itself uses lossless compression so the quality slider has no effect when keeping PNG format. Converting to JPEG or WebP will give significantly smaller files.
