Image Compressor
An image compressor shrinks the file size of JPG, PNG, and WebP images so they upload faster and load quicker. This one re-encodes your photo on a canvas at an adjustable quality level, shows the before and after size, and gives you a download link. Compression happens entirely in your browser, so your images never leave your device.

Are my images uploaded to a server?
No. The compressor processes everything locally in your browser using the canvas API, so your images are never uploaded anywhere.
Does compressing reduce image quality?
Lowering the quality slider trades some visual detail for a smaller file. The before/after preview and size readout let you find a balance that looks good while saving space.
