Compress many PDF files at once to an exact size and download them together as a ZIP. Free, private and in your browser — your documents are never uploaded.
Have a folder of PDFs that are all too big to upload? The bulk PDF compressor shrinks many PDF documents at once to an exact size and hands them back in a single ZIP folder. It is perfect for scanned paperwork, application documents and batches of reports.
Everything runs in your browser — no sign-up, no watermark, and your PDFs are never uploaded to any server.
Drop all your PDFs onto the bulk PDF compressor, set one target size, click Compress all, and Download all to get them in a ZIP folder — everything runs in your browser.

No. Every PDF is compressed locally in your browser, so your documents never leave your device.

A single ZIP folder containing every compressed PDF, named clearly by your target size.
Just one PDF? Use the single PDF compressor. For photos, try the image compressor or bulk image compressor, or start at the document resizer.
