TOOL OVERVIEW
About Compress Image
Modern photos from phone cameras are often several megabytes each. That is fine for local storage, but it is overkill for online forms, email attachments, and web pages where large files slow down page load speed and trigger upload limits. Compression shrinks file size by re-encoding image data more efficiently — removing redundant data while maintaining visual clarity that is virtually indistinguishable to the human eye.
