Email attachment limits and upload forms constantly reject PDFs that are just a little too big. This tool rewrites your PDF with a more efficient internal structure so it fits — and it does so without your file ever leaving your device.
The compression here is lossless: PrivtePDF repacks the PDF using object streams (a compact way of storing the document's internal objects) and strips bulky metadata left behind by scanners and office software. Text, images, and graphics are not re-encoded, so the visual quality is exactly the same as the original — nothing gets blurry.
This matters because a PDF you need to shrink is often exactly the kind of document you least want on a stranger's server: a lease, a payslip, a scan of your ID. Services like Smallpdf or iLovePDF process your file remotely; PrivtePDF does it in the browser, so there is zero upload and the result appears instantly.
Reduce file size, keep quality
PrivtePDF performs lossless structural compression — it never downsamples or re-compresses your images, so quality is guaranteed. The trade-off: text-heavy and office-generated PDFs shrink nicely, while a PDF that is essentially one giant scanned photo may only shrink a little, because most of its size is the image data itself.

Not here. PrivtePDF uses lossless compression — it reorganizes the file's internal structure and removes redundant metadata but never touches the images or text rendering. The output looks identical to the original.
Scanned PDFs are mostly photographic image data, and lossless compression can't shrink photos much. Tools that achieve huge reductions on scans do it by downsampling images, which visibly lowers quality — PrivtePDF deliberately doesn't.
No server-imposed limit, because there is no server. Your browser does the work, so even large PDFs are fine as long as your device has enough memory.
With PrivtePDF, yes — the file is processed entirely on your device and is never uploaded, so confidential contracts or statements are never exposed to a third party.
