Image Compressor

Understanding Image Compressor

Image compression reduces the storage required by a picture while trying to preserve useful visual detail. Smaller images are easier to share, take less space and can help pages load faster. This browser tool decodes the selected image and exports a new copy through Canvas. The original remains unchanged on your device.

How to use this tool step by step

Choose a JPG, PNG or WebP image. Adjust the quality slider, choose an output format and press Compress image. Compare the original and resulting file sizes, inspect the quality and use the download button to save the optimized copy. Lower lossy quality usually creates smaller files, but may introduce artifacts.

Benefits, practical tips and limitations

Photographs often work well as JPEG or WebP. Screenshots, line art and text-heavy images may look better as PNG. PNG is lossless and may not shrink an already optimized file. Keep an original copy and avoid judging quality only from a tiny thumbnail. Large images can require substantial browser memory.
