Choose the local path
Most online PDF compressors start by uploading your file. PDF Shrink starts with local processing, so contracts, scans, IDs, invoices, and forms can stay on the device you are using.
- Browser: compress a PDF in this browser and download the result.
- iPhone: compress PDFs offline with no network permission.
- Private files: avoid a server upload for paperwork you do not want copied elsewhere.
Best uses
- Reduce scanned PDFs before email upload limits.
- Shrink invoices, forms, and contracts for sharing.
- Try stronger compression for image-heavy files where text selection is less important.

FAQ
Does PDF Shrink upload my PDF?
No. The browser tool runs locally in your browser, and the iPhone app processes files on device without network access.
Can I compress a PDF to 200KB or 500KB?
Sometimes. Stronger rasterized compression and the app's Extreme level can reduce scanned PDFs a lot, but the final size depends on page count, images, and the original file.
Should I use the browser tool or the iPhone app?
Use the browser tool when you are already on a desktop browser. Use the iPhone app for private paperwork, repeated compression, batch work, or offline use.
