- Click the button and download the single merged PDF.
When to combine PDFs
Merging is the fastest way to combine PDF files into one document for a single submission: scans from different pages of a contract, several chapters of a report, or a batch of receipts for an expense claim.
The result is a clean, continuous PDF with all pages in the order you added them. Pages are copied losslessly, so text stays selectable and image quality is untouched.
Why merge PDFs in your browser
The merge happens locally, so your documents never leave your device. There is no upload, no queue, and no account to create.
It works free on any browser, on desktop or mobile. For offline merging on iPhone, the PDF Shrink app includes the same local processing with a one-time unlock.
FAQ
Are my files uploaded to merge them?
No. The merge happens locally in your browser and the combined PDF is created on your device.
How many PDFs can I merge at once?
As many as you like. Each added file becomes part of the combined document in the order you add it.
Does merging reduce quality?
No. Pages are copied losslessly, so text and images keep their original quality.
Can I merge PDFs and images together?
This tool combines PDF files. To include JPG or PNG images, convert them to PDF first with the images to PDF tool, then merge.
Is merging really free?
Yes, free in the browser with no sign-up. The PDF Shrink iPhone app offers the same features offline with a one-time unlock.
