One workbench, not 120 scattered tools
Every tool shares the same flow — set a target, compress, verify the result, then continue to the next step.
Exact size targets
Type the limit you need — 100KB for a form, 2MB for an email — and the workbench hits it, file by file.
Results you can verify
Every job ends with a report: before, after, reduction, and whether each file met its target.
A workflow, not dead ends
Finished compressing? The report suggests what to do next — resize, convert — so you stay in one place.
Every file type, one place
Images, PDFs, video, audio, archives and documents — all 120 tools under one consistent system.
