Large images slow down websites, fill up storage, and get rejected by upload forms with size limits. This free image compressor reduces your file size in seconds using a quality slider you control. Everything runs inside your browser, so your photos are never uploaded to any server.
How to use
- Drop your image, or click to choose a JPG or PNG file.
- Drag the quality slider until the size and look are right for you.
- Compare original vs compressed with the slider, then download.
Frequently asked questions
Is it really free?
Yes — there are no limits, no sign-up, and no watermark.
Do my images get uploaded?
No. Compression happens entirely in your browser, so your images stay on your device.
Will compression reduce quality?
You control the quality with the slider. At higher settings the difference is very hard to see while the file is still much smaller.
What format do I get back?
A compressed JPG, which gives the best size reduction for photos.
