Portal Limits
Prepare several PDFs for university portals, government forms, or client uploads using the exact same target size.
Secure & Private
Process uploaded PDF batches securely. We do not permanently store your files on our servers.
Set One Target for the Whole Batch
When every document in a folder must fit the same portal limit, individual compression is slow. Set one KB or MB target for the whole batch before uploading. The tool then works through the group so each PDF is prepared for the same requirement.

Keep Every PDF Reviewable
Bulk compression should not turn invoices, legal exhibits, or slide handouts into unreadable files. Make PDF smaller in batch while keeping text, layouts, and essential graphics clear enough for recipients to review. This matters when the batch is going to clients, students, or court portals.

Handle Large Files Without Repeating Uploads
Large source files should not force you back into a one-by-one workflow. Upload several heavy reports, manuals, or scanned packets and batch shrink PDF files in one session. It is built for teams that need the same compression step repeated across many documents.

How to Batch Compress PDFs Online

Step 1. Set One Batch Target
Choose the KB or MB limit that should apply to the whole file group. Setting the target first keeps every upload working toward the same result.

Step 2. Upload Your PDFs
Drag and drop multiple PDF files into the upload area. You can add several documents at once to process your entire group of files in one single action.

Step 3. Download the Finished Set
Review the final sizes across the batch, then download the optimized PDFs. Your documents are ready for email, portal upload, or shared storage.
