100% LOCAL PIPELINE
Batch compress · keep 2K/4K · zip in-browser

Only resizes if longer than this. Most photos are already smaller — size often barely changes here; use Quality / Exact size instead.

FAQ
- Will the file be exactly 200KB?
- We aim to stay under your target size (default 200KB). Depending on format and image complexity, the result is usually slightly below the limit—not byte-exact.
- Are my images uploaded to a server?
- No. No files are uploaded to servers. Compression runs in your browser with Web Workers—100% private.
- How is this different from Quality mode?
- Quality mode outputs at your chosen quality. Exact-size mode searches quality levels to meet a size cap. They are separate product behaviors.
