How the File Order Works

The order of the cards is the order used in the final document. If PDF A is first and PDF B is second, all pages from A are added before the pages from B.

Are My PDF Files Uploaded?

The merge operation in this version is performed in the browser using JavaScript. The selected PDF data is read locally and the new PDF is created in browser memory. The page loads PDF processing libraries from a public CDN, but the merge code does not require sending your selected documents to a Surfingskill server.

Is This PDF Merger Unlimited?

There is no simple fixed file-count limit coded into this tool, but a browser tool should not be described as truly unlimited. The practical limit depends on file size, PDF complexity, available device memory and your browser.

Tip: If a large merge fails on a phone, try fewer files at once or use a desktop computer with more available memory.
