Up to 25 PDFs — every page lands on one canvas you can freely arrange
Merging PDFs is the single most common document task in office life: application packets, board packs, invoice bundles, onboarding kits. Merge PDF combines up to 25 files into one document while preserving each page exactly — original dimensions, orientation, and quality are untouched, and mixed portrait/landscape documents merge cleanly.
Unlike upload-based mergers, your files are read directly by your browser. That matters when the files are offer letters or bank statements: there is no server copy, no retention window to trust, and no upload wait for large files. Encrypted PDFs are supported too — enter the password and it is used only on your device to unlock the file for merging.
Drag files to set the order (or use the arrow buttons — the whole flow works by keyboard), name the output, and download. If you need page-level control across documents, merge first and then fine-tune in the Reorder PDF Pages tool.
Drop two or more PDF files into the tool, or click to pick them.
Drag the files (or use the arrow buttons) into the order you want them to appear.
If a file is password-protected, enter its password when prompted — it is used only in your browser.
Optionally edit the output filename.
Click Merge and download the combined PDF.
Merging combines whole files in file order; use the Reorder PDF Pages tool afterwards for page-level rearranging. Form fields from source documents may become static in the merged output. The merged file is saved without encryption — re-protect it with the Protect PDF tool if needed.
Drop your PDFs into this tool — merging happens inside your browser using local processing, so the files never travel over the network. You can even disconnect from the internet after the page loads and merging still works.
No. Pages are copied into the new document byte-for-byte, keeping their original dimensions, orientation, fonts, and image quality. Mixed page sizes and landscape pages are preserved exactly.
Yes. When an encrypted file is added you'll be asked for its password, which is used only on your device to unlock the file for merging. The merged output is unprotected — use the Protect PDF tool afterwards if you want the result encrypted.
Up to 25 files and 400 MB per merge job. The limit protects your browser's memory (everything runs locally), not a business model — there is no daily quota.
Merge combines whole files in your chosen order. For page-level control, merge first and open the result in the Reorder PDF Pages tool, which gives you a draggable thumbnail grid of every page.
