Compress Image Files for Free

Compress image files for free, with no sign up. Adjust quality and width to compress photo files on your device. Nothing is uploaded.

Lower quality can save more space. PNG uses a color palette, so results vary by image.

Images keep their proportions and are never enlarged. Very large images may be limited further by your browser.

Drag the divider or use the arrow keys to check your first image for lost detail; the line above gives both file sizes and the saving.

    How to use this tool

    To compress photo files, choose JPEG, PNG or WebP images, set quality and maximum width, then save each result.

    Frequently asked questions

    Do my files leave my device?

    No. Each file never leaves the device. Compression runs in your browser with nothing uploaded. The compression library is included locally.

    Which image formats can I compress?

    Choose JPEG, PNG or WebP files, including several at once. Results keep the original format when your browser supports it. Any format fallback is shown with the result.

    Will the tool compress image files to a smaller size every time?

    No. When you compress picture files, some are already small. If a result is larger, the tool keeps the original and reports zero space saved. Lower quality or a smaller width may help.

    Does compression change my image?

    A smaller width resizes the image, and lower quality may remove detail. Compressed JPEG results omit camera metadata. Keep your original if you need its full quality or metadata.
