How It Works
Merge PDF combines every page from your selected files into one document, in the order you arrange them. Processing runs entirely in your browser with pdf-lib: your files are not uploaded to a server for merging, which helps keep contracts, resumes, and personal documents private on your device.
How to Use
- Add two or more PDF files. You can select multiple files at once or add them in batches.
- Drag files in the list to reorder pages if your uploader supports reordering—order here is the order in the final PDF.
- Click “Merge PDFs” and wait until the merged file is ready.
- Download the combined PDF, or start over to merge a different set.
Common Use Cases
- Joining separate chapters or invoices into one file for submission.
- Combining signed forms and attachments for HR or legal packets.
- Building a single portfolio from multiple exported PDFs.
- Merging lecture notes or scanned pages in the correct sequence.
FAQ
- Does merging PDFs online reduce quality?
- Merging copies existing pages into a new file; it does not re-encode images unless the underlying library normalizes content. Visual quality should match your originals. If something looks off, confirm each source PDF opens correctly on its own.
- Can I merge password-protected PDFs?
- Encrypted or password-protected PDFs may fail to load in the browser until they are unlocked in a desktop reader and re-saved without encryption, or you use a tool that supports your password flow.
- Is my data uploaded when I merge PDFs here?
- Merge runs locally in your browser: file bytes stay on your machine during the operation. That is a strong privacy fit for sensitive documents, provided your device is secure and you trust your network.
