Compress Image

It depends on the image and the quality setting. Photographs commonly drop 50–85% at 75–85% quality with little visible difference. Screenshots and graphics with flat colors often shrink even more when converted to WebP. The tool shows you the exact savings before you download.

No. Compression changes the file encoding (and therefore the file size), not the pixel dimensions. Your image keeps its original width and height unless you enable the optional "shrink images wider than 2560px" setting. If you need specific dimensions, use the Resize Image tool.

For web photos, 75–85% is usually the best balance. Use 90%+ for print or archival copies where quality matters most. Below 60% you will start to see visible blocking and artifacts, especially in gradients and skin tones.

PNG is a lossless format, so the quality slider does not apply to it. To shrink a PNG significantly, choose WebP or AVIF as the output format, or reduce its dimensions with the Resize tool. The tool labels rows where no size gain is possible.

No. Compression runs entirely in your browser using the Canvas API. Your files are decoded, re-encoded, and kept in memory on your device. Nothing is sent to ImgSprint or any third party.

Yes. Add as many files as you like and they will all be processed with the same settings. The practical limit is your device memory rather than a server quota, so on phones it is best to work in groups of 10–20.

Re-encoding through the canvas drops most EXIF metadata such as GPS coordinates and camera settings as a side effect. If you specifically want to remove metadata while keeping the original encoding, use the Remove Image Metadata tool.
