Compress Image - Reduce File Size
Large photos can be hard to upload, slow to email, and heavy for websites. This image compressor helps reduce file size while keeping the picture clear enough for normal use. It is useful for product photos, blog images, portfolio pictures, online forms, school documents, and social media uploads. Use the quality slider to choose a smaller file or a clearer image, then compare the result before downloading.

Questions
Frequently asked questions
How much can I reduce an image size?
It depends on the original format, dimensions, and quality setting. Photos usually compress more than flat graphics or already-optimized files.
Why does the compressed image look different?
Lower quality settings can remove small details to reduce file size. Use the preview and raise the quality if the image looks too soft.
Will compression damage my original file?
No. The original stays on your device, and the compressed image is downloaded as a new file.
