How to Compress Multiple PDF Files at Once (Batch Compress)

You have ten scanned bills, a folder of certificates or a month of reports, and every file is too big to email or upload. Compressing them one by one means opening the tool, adding a file, waiting, downloading, and repeating the same steps again and again.

The faster way is to compress many PDFs together in one go.

When do you need batch compress?

• A folder of scanned documents that are all too large
• Many bills or receipts to send for a claim or reimbursement
• Student or office files that must fit an upload limit
• Freeing storage space on your phone or computer

Tips

Check a few results. Open two or three files after compressing, to be sure the text and images are still readable.

Keep your originals. The tool creates new files, so keep the first copies until you are sure.
