How to merge PDFs online
Combining multiple PDF files into a single document is one of the most common PDF tasks — whether you are assembling a report from separate chapters, pulling together signed contracts, or packaging design proofs for a client. PDFRift makes the process instant and private: every step runs in your browser, so your files never touch a remote server.
Step-by-step
- Click the upload area above or drag and drop the PDF files you want to combine.
- Reorder the files by dragging them into the sequence you need.
- Press "Merge" and your combined PDF will be ready to download in seconds.
Why merge PDFs in the browser?
Most online merge tools upload your documents to a remote server, process them in the cloud, and send the result back. That round-trip introduces privacy risks and adds latency. PDFRift takes a different approach: all merging is handled by pdf-lib running inside your browser tab. Your files stay on your device from start to finish, which means there is nothing to intercept, no server logs of your documents, and no waiting for an upload to complete. This makes it the best choice for sensitive documents such as legal agreements, medical records, and financial statements.
Common use cases
Assembling reports
Combine a cover page, table of contents, individual chapters, and appendices into a single PDF you can email or upload to a document management system.
Packaging contracts
Collect separately signed pages from multiple parties and merge them into one final executed copy.
Organising schoolwork
Students can merge lecture notes, assignments, and reference material into one study document.
Tips for merging PDFs
- Put your files in the correct order before you merge — the tool combines them top to bottom.
- If one of the source PDFs is password-protected, remove the password first using the Protect PDF tool.
- Large files (over 10 MB) may take a moment to process in the browser. On the free tier the maximum file size is 10 MB; upgrade to Pro for files up to 150 MB.
Frequently asked questions
Is there a limit on how many PDFs I can merge at once?
Free users can merge up to 5 files per operation. Pro and Business subscribers can merge up to 50 files at a time.
Will the merged PDF keep bookmarks and links?
Yes — PDFRift preserves bookmarks, hyperlinks, and annotations from each source file.
Does merging reduce quality?
No. The pages are combined without re-encoding, so text, images, and vector graphics remain pixel-perfect.
