What is Merge PDF?
Combine several PDFs into one document — useful for bundling scanned pages, assembling application packets or joining chapters into a single report. Add as many files as you need, reorder them, and download one merged PDF.
How to use Merge PDF
- Select two or more PDF files, or drop them anywhere on the page.
- Use the ↑ and ↓ buttons to arrange the files into the order you want them to appear.
- Remove any file you added by mistake with the ✕ button.
- Click “Merge PDFs” — the combined file downloads straight to your device.
Why use this tool?
No file size limits
Most online mergers cap free uploads at a few megabytes. Because merging happens locally, the only real limit is your device’s memory.
Safe for confidential documents
Contracts, medical records and financial statements are never transmitted anywhere, which makes this safe to use for sensitive paperwork.
No watermarks
The merged PDF is clean. Nothing is stamped onto your pages and nothing is added to the file.
Frequently asked questions
How many PDFs can I merge at once?
There is no fixed limit. Merging happens in your browser’s memory, so very large batches on an older device may be slow, but dozens of ordinary documents are fine.
Does merging reduce quality?
No. Pages are copied across exactly as they are, so text stays selectable and images keep their original resolution.
Can I merge password-protected PDFs?
Encrypted PDFs may fail to load. Remove the password in your PDF reader first, then merge.
Are my files uploaded to a server?
No. Every tool on Toolraq runs entirely inside your browser using JavaScript and WebAssembly. Your file never leaves your device — there is no upload endpoint at all. You can verify this yourself by opening your browser’s DevTools Network tab while you use the tool.
