Merge PDF Files
Combine multiple PDF files into a single document. Process everything locally in your browser.
Key Capabilities
Drag to reorder before merging
Arrange files in whatever order the final document needs, then combine them into one.
Bookmarks carry over, per file
Each source file's internal bookmarks survive the merge; a single unified outline across all files isn't generated automatically.
A practical ceiling around 30 files or 500 pages
Governed by your browser's available memory rather than an artificial limit — most merges are well under that.

Frequently Asked Questions
Is there a file size or page limit?
No. Because DoctorDocs processes the files locally in your browser, there are no artificial server limits. You can merge dozens of PDFs simultaneously, limited only by your device's RAM.
Who uses this merge tool?
Attorneys merge pre-trial pleadings and evidence exhibits into single electronic filing packets. Real estate brokers combine seller disclosures and purchase agreements. Students merge downloaded journal articles into comprehensive study guides.
Can I reorder the files before merging?
Yes. After uploading your PDFs, you can easily drag and drop the files into your desired chronological or thematic sequence before clicking merge.
Are my confidential PDFs uploaded to the cloud?
No. The merging algorithm executes entirely within your browser using secure, client-side WebAssembly. Your corporate contracts, tax disclosures, and legal filings never leave your device.
