Local PDF merge tool
Merge PDF files without uploading them
Combine a report and appendix, a contract packet, or a set of scans directly on your device. pdfmend keeps the first open PDF and every added file inside the browser, then exports one clean document.
No upload · No account · No watermark
- Combine up to 10 PDFs per merge

Four local steps
How to combine PDF files
A merge starts with one open document. The editor then adds up to nine more files behind it in the order you select them.
Open the PDF that should come first
Choose the cover document or first section from your device. It stays as the beginning of the combined file.
Choose Merge PDFs
Select up to nine additional PDFs. The browser reads each file locally; there is no batch upload or temporary server copy.
Inspect and organize the pages
Use the Pages sidebar to move, rotate, duplicate, or remove individual pages after the files have been combined.
Export one finished document
Download the merged PDF, or choose Compress when attachment size matters. Results vary with the kind of content in the source files.
Build the file in the order you actually need
The PDF already open in the editor is input one. Pages from the selected files follow it, file by file. That predictable rule makes it easy to assemble a cover letter, main report, supporting exhibits, and appendix without renaming every source first.
If a page lands in the wrong place, the merge is not ruined. Select the page in the sidebar and move it up or down. Sideways scans can be rotated, blank pages can be removed, and a cover sheet can be duplicated before export.
- Count the open PDF as one of the 10-file limit.
- Keep the combined input under 100 MiB and the result under 250 pages.
- Merge in batches if a job is larger than the current limits.
Edit the combined document before downloading it
The merged result is a normal document in the editor. You can add a title, date, page note, highlight, image, or visible signature before saving the final copy. Existing local edits in the first document remain part of the work rather than forcing you to start over.
Password-protected inputs can be opened with passwords entered locally. A digitally signed input is rejected for merging because rebuilding the file would invalidate its signature. Added files become part of a fresh copy; apply Protect to the final export if the result needs an opening password.
One local merge instead of many uploaded documents
A server-based merge exposes every input as well as the combined result. A five-file job can create six remote document copies in one step. That is especially uncomfortable for tax packets, invoices, identification scans, or legal exhibits.
pdfmend loads the selected bytes into browser memory, combines the pages on your device, and writes the result to a browser download. There is no document upload endpoint and no account is required. Plausible receives only content-free usage buckets, never filenames, page text, or PDF bytes.
Straight answers
Frequently asked questions
How many PDF files can I merge at once?
Up to 10 files: the PDF already open plus as many as nine additional PDFs. The combined limit is 100 MiB and 250 pages during the free launch.
Can I change the page order after merging?
Yes. The merged document stays open in the editor, where the Pages sidebar can move, rotate, duplicate, or remove individual pages before export.
Can I merge a password-protected PDF?
Yes, when the file can be opened with a password you enter locally. Existing digital signatures are different: merging would invalidate them, so signed inputs are rejected.
Does merging upload every source file?
No. Each input is read by your browser and combined on the device. Neither source files nor the merged PDF are sent to pdfmend.
