PDF, images, ZIP · up to 200 MB · processed on this device
Add PDFs, images, TXT, Markdown or CSV/TSV. ZIP folders work too. Files stay on your device.
Drag files into order, or use Earlier and Later. The merged PDF follows that sequence.
Click Download PDF. If the merged file is large, run it through Compress afterwards.
Scattered documents are harder to share, harder to archive, and easier to lose. Here's when combining them makes sense:
Client deliverables
Combine a proposal, contract, and appendices into one professional package instead of sending three attachments.
Expense reports
Merge receipts, invoices, and the expense form into a single PDF for accounting.
Research & reference
Combine journal articles, notes, and citations into one searchable document.
Application packets
Merge your resume, cover letter, portfolio, and references for job or school applications.
Drag to reorder
Grab any file and move it to change the page order in your final document.
Remove files

Is there a limit to how many PDFs I can merge?
Up to 50 files, subject to the displayed device-safety limits. The practical constraint is browser memory — for best performance, keep the combined size under 50MB. Very large merges might slow down on older devices.
Do bookmarks and page numbering survive a merge?
Yes. Every document keeps its own bookmarks, each re-pointed at wherever its pages ended up, and its own page numbering — merge roman front matter with a lettered appendix and you get both, not a renumbering of either. Where two documents disagree on something a file can only do one way — viewer preferences, the opening page mode, the page layout — the first document in your order wins, so dragging a different file to the top changes which one leads. Form fields still fill in; if two documents use the same field name, the second becomes “Name (2)” so typing in one does not overwrite the other. Accessibility tags do not carry over.
Can I merge password-protected PDFs?
Not directly. If a PDF is encrypted, you'll need to remove the password first (using Adobe Acrobat or a similar tool). Once the file is unprotected, it merges normally.
Will bookmarks and links be preserved?
Yes. Bookmarks, links between pages and form fields come through, each pointing at its own document’s pages in the merged file. Links to websites are untouched. Accessibility tags and existing digital signatures do not survive a merge.
Does merging affect quality?
No. Merging is lossless — we copy page objects directly without re-encoding. Image resolution, text sharpness, and vector graphics remain identical to the source files.
