Merge PDF

Combine up to 20 PDF files into one document in your browser. Drag to reorder pages before download—free, private, no upload.

Can I change the order of merged PDFs?

Yes. Drag files in the list before merging. Pages append in list order: the first file's pages come first, then the second file, and so on. Put cover letters first and appendices last when preparing application packets.

What are the file count and size limits?

You can merge up to 20 PDFs with a combined size around 25 MB. Larger sets may hit browser memory—merge in batches, then merge the batch outputs, or compress with Compress PDF first.

Can I merge password-protected PDFs?

Encrypted PDFs must be unlocked and saved without a password before merging. The browser cannot decrypt protected files without credentials. Remove protection in a desktop reader, then select the unlocked copies here.

Does merging reduce PDF quality?

Merge copies pages as-is without recompressing images. Output size is roughly the sum of inputs. Use Compress PDF afterward if email or portal limits require a smaller file.

Are my PDFs uploaded to a server?

No. Processing uses pdf-lib entirely in your browser. Contracts, medical records, and tax forms stay on your device—prefer this over upload-based merge sites for sensitive packets.

What if some pages are sideways?

Rotate individual files with Rotate PDF before merging so the combined document scrolls consistently. Fixing orientation after a large merge is harder to undo cleanly.

Can I merge the same file twice or insert a section in the middle?

Add the same PDF twice to the list if you need repeated sections—each list entry appends its full page range in order. To insert a packet in the middle, drag that file between the two surrounding items before clicking Merge. There is no per-page picker; split oversized sources first if you only need selected pages.

Need PDF to images, images to PDF, or text extract?

Use sibling tools on this site: PDF to Images (PDF to PNG/JPG), Images to PDF (JPG/PNG to PDF), and PDF Text Extractor for plain-text convert-PDF-doc style extracts. Pair with Merge, Split, or Compress PDF for a full browser-local toolkit—no uploads.

Is Merge PDF free?

Yes. Free with no login, watermarks, or daily merge caps.

Can I reorder files before merging?

Yes. Arrange the file list in the exact order you want the final PDF to read—cover first, appendices last. Preview page counts mentally: a scanned appendix with many images will dominate file size after merge, so compress heavy sections first when emailing.

Are bookmarks and forms preserved when merging?

Browser merge focuses on concatenating page streams reliably. Complex interactive forms, some JavaScript actions, or exotic encryption features may not survive every merge path. For critical interactive PDFs, verify fields after download or keep the interactive file separate.

How do I keep merge order correct for multi-author packets?

Name source files with numeric prefixes (01-cover, 02-body) before uploading, then drag in the UI to confirm. After merge, jump to page boundaries between sections to ensure no blank or duplicated cover slipped in. If each source was compressed differently, merge first only when you still need edits; otherwise compress the final merged file once.
