What this tool is for
The Merge PDF tool combines several PDF files into a single document, in whatever order you choose. It's built for anyone who ends up with related PDFs scattered across different files and needs one clean document instead — no design software, no printing pages just to staple them together.
Practical use cases
- Job applications: combine your resume, cover letter, diplomas and references into one PDF before uploading it to a job board.
- Invoicing and admin: group several invoices or receipts from the same month into a single file for your accountant.
- Scanned documents: merge multiple single-page scans from a scanner or phone app into one multi-page PDF.
- Reports and contracts: assemble a cover page, main document and appendices into one file before sending it for signature.
How to use this tool
- Drop your PDF files into the upload area, or click it to select them from your device.
- Reorder the files using the arrow buttons if the order they were added in isn't the order you want in the final document.
- Remove any file added by mistake using the delete button next to it.
- Click "Merge", check the preview of the first page, then download the finished PDF.
Key benefits
- No limit on the number of files you can merge in one go.
- Simple drag-free reordering before the final merge.
- Fully local processing: your files never leave your device.
Practical tips
- Double-check the file order before merging — it directly determines the page order in the final document.
- For a job application, the usual order is: resume, cover letter, diplomas, then supporting documents.
- If a file doesn't need to be included after all, remove it before merging rather than editing the PDF afterwards.
Common problems
If a PDF fails to load, it may be password-protected or corrupted — try opening it in a PDF reader first to confirm it isn't damaged. If merging feels slow, it's usually because one or more files are very large or you're combining a high number of PDFs at once; splitting the job into two smaller merges can help on lower-powered devices.
Good to know
The merge runs entirely in your browser using a PDF processing library loaded on demand. No file is ever uploaded to a server, so your documents stay private throughout the process.
Frequently asked questions
Is there a file size limit?+
There's no limit set by the tool itself, but merging a large number of heavy PDFs can slow down processing depending on your device's performance.
Is the page order inside each PDF preserved?+
Yes, each PDF keeps its own internal page order; only the order of the files relative to each other can be changed.
Can I merge scanned images along with PDFs?+
This tool merges PDF files only. If you have images (JPG or PNG), convert them to PDF first using the JPG/PNG to PDF tool, then merge the result here.
