Combine multiple PDF files into a single document. Everything happens locally in your browser — your files are never uploaded anywhere.
What does this tool do?
This tool combines two or more PDF files into a single PDF document, keeping every page's original text, images, and formatting exactly as they were — nothing is rasterized or re-rendered as an image. The result is a real, editable-quality PDF, not a scanned-looking copy.
When should you use it?
- You have several separate PDF reports, invoices, or chapters and need one combined file
- You're assembling a portfolio or application packet from multiple documents
- You scanned a document in parts and need to combine the pages into one PDF
- You want to send several related documents as a single attachment
Why use Orisod for this?
The merge happens entirely in your browser using pdf-lib — your PDFs are never uploaded to a server. You can reorder files before merging using the up/down arrows, remove any file you don't want included, and the final document keeps full text selectability and original quality.
Frequently asked questions
Does merging affect the quality or text of my PDFs?
No. Unlike tools that convert pages to images first, this tool merges the actual PDF content — text stays selectable and searchable, and image quality is unchanged.
Can I change the order of the files?
Yes, use the up and down arrows next to each file to reorder them before merging.
Is there a limit on how many PDFs I can merge?
There's no fixed limit — you can combine as many files as your browser's memory can comfortably handle.
Are my files uploaded to a server?
No. The entire merge process runs locally in your browser using JavaScript — nothing is sent anywhere.
