About the image compressor
Reduce the file size of photos and graphics so they upload faster and take up less space, without installing anything. Drop the quality a little, or switch to WebP for the biggest savings, and preview the resulting file size before you download. All compression happens in your browser's canvas, so your images are never uploaded — great for private pictures.
Frequently asked questions
Are my images uploaded?
No. Compression happens in your browser using an HTML canvas. Your images never leave your device.
How does compression work?
The image is re-encoded at a lower quality setting (and optionally as WebP, which is very efficient). Lower quality means a smaller file; you can preview the result size before downloading.
Which formats can I use?
JPG, PNG and WebP input. Output as JPG or WebP for the best size savings, or PNG for lossless.
