Why convert JPG to JPG?

Modern phone cameras produce huge JPGs - 5 to 12 MB is normal for a single photo. Most websites, email systems, and chat apps choke on that. Compressing a JPG cuts the file size by half or more with no visible quality loss, which is the difference between attaching three photos to an email and getting "attachment too large".

We decode your JPG, optionally resize the longer side to a max pixel cap (default 2048px - plenty for displays), then re-encode at the quality you pick (default 75% - visually indistinguishable on most content). Both knobs combine for dramatic size reduction. Output is a fresh JPG ready to attach, upload, or share.
