PDF Tools
Merge PDFs
Join two or more PDF documents into one file in the order you choose. The tool copies PDF pages locally in your browser, so ordinary text and vector page content are not converted to screenshots.
✓ Every tool runs in your browser. We do not upload your input or output.

How to use
- Choose or drop two to ten PDF files and check the list order.
- Use the arrow controls to put the documents in the desired sequence.
- Create the merged PDF, review its reported page count, and download it.
Examples
Combine a project packet
Each source's pages remain together. Move a file up or down to change the sequence before creating the result.
proposal.pdf (4 pages), estimate.pdf (2 pages), appendix.pdf (3 pages)
merged.pdf with 9 pages in that document order
Assemble a release handoff
The new document copies pages from both inputs. Check links, forms, and bookmarks separately because document-level features may not survive merging.
release-notes.pdf followed by test-report.pdf
One PDF with release notes first and the report second
Keep pages in the right sequence
Merging is useful when several PDFs form one packet: a proposal and appendix, a set of reports, or release notes with a test summary. The file list is the merge order. The first file contributes the opening pages, followed by every subsequent file. Use the arrow buttons if the browser’s file picker returns a different order than intended.
The tool copies PDF pages into a new document rather than drawing screenshots of them. For ordinary documents, text and vector artwork on the pages generally remain available at their original quality. That makes merging different from converting each page to PNG and putting the images into a new PDF. The new file is not necessarily a perfect copy of every document-level feature, however. Bookmarks, interactive forms, attachments, scripts, and signatures may not carry over or remain valid. Signed PDFs in particular should be handled in a workflow designed for signatures.
If your sources are photographs or screenshots, Images to PDF is the right starting point. If you need just one page as an image for a presentation, use PDF Page to PNG.
Limits and verification
The merge runs locally in a browser worker; the files are not sent to a server. Up to ten PDFs are accepted, with a 20 MB limit per file, 60 MB combined limit, and 250-page result limit. Password-protected or damaged PDFs cannot be merged. After downloading, open the file and check page order, page count, text selection, links, and any features your recipients need. The page count shown by the tool is a quick check, not a substitute for reviewing the finished document.
Frequently asked questions
Are the PDFs uploaded?
No. They are read in a browser worker and the merged PDF is created locally.
Does merging keep selectable text?
The pages are copied as PDF pages rather than rendered to images, so ordinary text and vector content generally remain. Check the result for document-specific features.
Will bookmarks, forms, or signatures work afterward?
Do not rely on them being preserved. Page copying does not guarantee document-level bookmarks, form fields, or digital signatures. Inspect the result before use.
Can I merge encrypted PDFs?
No. This tool requires PDFs that can be opened without a password.
What are the limits?
Choose 2 to 10 files under 20 MB each and 60 MB total. The merged document is limited to 250 pages.
