PROCESSING TRANSPARENCY
Trust center ↗Know what happens before you upload.
A temporary per-request workspace is cleaned when processing ends.
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.
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.

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.
When this tool makes sense
Combining reports, contracts, assignments, or other PDFs into one document while preserving the order you choose.
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.
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.
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.
