Free · No watermark · Private — your image never leaves your browser
No upload wait and no queue — the image is processed on your device the moment you drop it in.
The whole thing runs in your browser on your device. Your image is never sent to a server.
Process as many images as you like. No sign-up, no watermark, no file-size paywall.
How it works
Large images slow down websites and fill up storage. This compressor re-encodes your image at a smaller size right in your browser: drop in a PNG, JPG or WebP and pick a compression level. Each level shows its exact file size and the percentage saved, so you download the balance you want. Nothing is uploaded, so even private images stay on your device.
Frequently asked questions
How much smaller will my image get?⌄
It depends on the image, but a PNG photo compressed to WebP often drops 70 to 90 percent in size with no visible loss.
Will it lose quality?⌄
Barely, if at all. Pick 'High quality' for near-identical results or 'Smallest' for the biggest savings. Quality never drops below a usable floor, so it won't look trashy.
Is my image uploaded?⌄
No. Compression happens entirely in your browser and the image never leaves your device.
