What is a JPEG Compressor?
A JPEG compressor reduces the file size of a .jpeg image by re-encoding it at a chosen quality level. JPEG and JPG refer to the exact same image format — this page exists as a direct match for people searching "compress jpeg" specifically, and uses the same reliable compressor as our Compress JPG tool.
