CABOKIT TOOLKIT
Free Local Image
Compressor
No files uploaded to servers — 100% private, free, and unlimited. Compress in your browser, then download ZIP.
100% LOCAL PIPELINE
Batch compress · keep 2K/4K · zip in-browser
Web Worker concurrency with no backend server. Built for indie sites and ecommerce product-image batches.
Only resizes if longer than this. Most photos are already smaller — size often barely changes here; use Quality / Exact size instead.
Tip: Max edge keeps 2K/4K fidelity—it won't shrink small images. To force a smaller file, lower Quality or switch to Exact size.

FAQ
- Why emphasize No Upload?
- Many optimizers upload files first. Cabokit is truly local: better privacy, faster feedback, and no upload bandwidth bottleneck.
- Does it send hidden network requests?
- The compression pipeline doesn’t depend on a backend API. Check your browser Network panel—you shouldn’t see image uploads during compression.
- Is it suitable for company assets?
- Yes. Perfect for corporate assets and designers. Need Discord Bot / internal workflow integration? Ask about a private script.
