Any file, lighter.
In one move
Drop a single file or a whole folder. Optilapse finds everything it can compress inside and asks before it starts.
Each format has its own tuned encoder, so one level means the same thing for a photo, a deck and a screen recording.

Nothing changes
but the size
No settings to learn
One choice, and most people never touch it. Optimal makes files much smaller with nothing you would notice. Hard goes as far as is still sensible.
Works offline
Everything happens right on your Mac. No account, no sign-in, no waiting for an upload.
Never makes things worse
If a file is already as small as it gets, it stays as it is. Compressing twice is never worse than once, so a picture can't wear down by accident.
Same file, lighter
Same format, extension and resolution. Dates and Finder tags are kept. In a PDF, text, links, forms and the outline stay exactly as they were.
Honest about every file
Each file gets its own line: how big it was, how big it is now, what you saved. If one couldn't be compressed, you see why.
Right from Finder
Right-click any file or folder and choose Optilapse. Changed your mind? Revert to the original in one click.
Also in your terminal
The same engine as a command-line tool. Results come out as JSON, one line per file, so Claude Code, Cursor or Codex can shrink a project's assets for you.
