Image Compressor
Compress JPEG and WebP images to a smaller file size right in your browser.
Upload a JPEG, PNG, or WebP image to compress it in your browser.
What is this tool?
An Image Compressor reduces an image file size by lowering its encoding quality, trading a small amount of visual detail for a much smaller file.
How does it work?
The tool draws your image onto an in-memory canvas and re-encodes it at the quality level you choose using your browser’s built-in image encoder.
How to use Image Compressor

Pro Tips

Frequently Asked Questions
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API — your image never leaves your device.
Which formats can I compress to?
JPEG and WebP, since both support adjustable quality. PNG is lossless and does not use a quality setting.
