Compress images without uploading them anywhere
Big image files slow down websites, fill up inboxes, and eat storage. This image compressor re-encodes your picture at a smaller file size using your browser's built-in graphics engine. Drag the quality slider and watch the size — and the savings — update before you download. Because all the work happens on your device, your images are never sent to a server.
Tips for the best results
- Photos: choose JPG at 70–85% quality for the best balance of size and clarity.
- Smallest possible file: switch to WebP — it usually beats JPG at the same quality.
- Web use: set a max width (e.g. 1600px) so huge camera images are resized down before compressing.
Frequently asked questions
Are my images uploaded?
No. Compression happens entirely in your browser using the HTML canvas. Your images never leave your device.
Does compressing reduce quality?
Lossy formats like JPG and WebP discard some detail to save space. At 70–85% quality the difference is usually invisible while the file gets much smaller.
Why is my PNG bigger after compressing?
PNG is lossless, so photos often shrink far more when exported as JPG or WebP. Try both formats to see which is smaller.
