Make JPGs dramatically smaller for e-mail, forms, and faster pages — re-encoded on your device at the quality you pick. Originals are never touched or uploaded.
The converter
Drop in one image or a whole batch. Everything is converted on your device — no upload, no wait.
How it works
Shrink one JPG or a whole batch without sending anything to a server.
01
Pick a file or drag it straight in — drop in .jpg or .jpeg photos.
02
Slide between smaller and sharper. 80 is a great default for most photos.
03
It saves straight to your device the moment it’s ready — no upload, no waiting.
Why compress JPG
Learn
Phone and camera manufacturers save JPGs at very high quality settings because storage is cheap and nobody complains about too much detail. A 12-megapixel photo routinely lands at 4–8 MB — of which the visible image is maybe one megabyte. The rest is insurance you are now paying to e-mail, upload, and host.
Re-encoding that photo at quality 75 typically cuts it by more than half, and often by 80%. Side by side at normal size, you will not find the difference.
First: repeated re-compression. Each lossy save adds artifacts on top of the last. Compress once, from the original, and archive the original. Second: over-compressing images with text or sharp graphics — JPG artifacts cluster around hard edges, so screenshots and scans with text want quality 85+ or a lossless format instead.
Everything here runs locally, so experimenting is free: try 75, open Compare, and step down until you see a difference — then go one step back up.
FAQ
Camera photos at quality 75 usually shrink 40–80%, depending on how they were originally saved. Already-optimized JPGs shrink less.
75 is ideal for sharing and web use. Use 85–90 when detail matters (portfolios, print), or 60–70 to squeeze under strict form limits.
Repeated lossy re-saves compound artifacts. Compress from the original once rather than re-compressing a compressed file, and keep your original.
Yes — the entire compression runs in your browser. Your photos never reach a server.
Quality 70–80 hits the sweet spot for photos on the web. Below 60, artifacts become visible in gradients and skin tones; above 85, files grow with no visible gain.
