01Where it runs

Infinity server-side PDF merge

02File lifetime

A temporary per-request workspace is cleaned when processing ends.

03Known limits

Final order follows the file order before processing. Encrypted or damaged PDFs may fail to open, so keep the originals. Merging does not repair page layout or automatically remove duplicate pages.

04Verify after download

After download, inspect the first and last page plus every boundary between source files. Recheck page numbering and the table of contents for formal documents.

Workspace

Upload your file to start

Ready

Sample files contain demonstration content only. They are included so you can test the workflow before using your own data.

INFINITY INTELLIGENCE

A copilot that understands this tool.

Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.

PRACTICAL CONTEXT

What this tool is good at — and where to be careful.

BEST FOR

When this tool makes sense

Combining reports, contracts, assignments, or other PDFs into one document while preserving the order you choose.

HOW IT WORKS

What the engine actually does

The tool reads each PDF in the selected order, creates a new document, and appends pages one by one. If the first PDF contains usable metadata, the tool attempts to preserve it. Page content is not rasterized or rewritten into images.

LIMITS

What it does not promise

Final order follows the file order before processing. Encrypted or damaged PDFs may fail to open, so keep the originals. Merging does not repair page layout or automatically remove duplicate pages.

CHECK

A 20-second quality check

After download, inspect the first and last page plus every boundary between source files. Recheck page numbering and the table of contents for formal documents.

Frequently asked questions

Does merging reduce page quality?

The pages are appended as PDF pages rather than re-rendered as images.

Can I control the order?

Yes. Reorder the upload list before processing; that order is used for the output.
