Compress image file size
Shrink photos and images to hit your target file size (KB or MB). Perfect for bypassing upload limits on chat apps, forums, and job applications. We adjust quality levels automatically to keep your images sharp without uploading them to a server.
Choose JPG or PNG files
Drag and drop multiple files at once
How to use
- 1
Drag and drop the JPG or PNG files you want to shrink, or click to upload them. You can process multiple files at once.
- 2
Set your target file size and select the unit (KB or MB). For example, 1MB works well for profile pictures.
- 3
Adjust your minimum quality floor and output format if needed. Setting the quality floor too low might hit your target size but make the image look pixelated.
- 4
Click "Compress" to automatically find the best quality that fits under your limit. Grab all your files in a ZIP if you converted multiple images.
FAQ
- Will the output match my target size exactly?
- We target a file size at or below your limit. We adjust quality increments to get as close as possible without going over. If we hit your minimum quality floor first, the final file might stay slightly larger than your target.
- How does compression affect image quality?
- Reasonable target sizes shrink your files without any visible difference. The smaller your target size compared to the original, the more details you might lose. Increase your target size or raise the minimum quality floor if you need higher fidelity.
- Can I compress PNG files?
- Yes. We support PNG compression, but exporting PNGs as JPGs yields much better size reductions. We recommend JPG outputs for photos and screenshots that don't require transparency.
- Do you upload my images to a server?
- Never. We handle all compression locally in your browser. Your files never leave your device and clear from memory as soon as you close the page.
