FAQ

Why does it say "custom size"?

It means the page size is not one of the common papers — scans, brochures exported from design software and PDFs assembled from screenshots all land here. The tool will not call 106 × 141 mm "A5" (148 × 210 mm), because that would have you print with the wrong paper setting and lose the edges of the page. You get the real millimetres and can decide which paper to use.

Can I change the metadata?

This tool only reads. To change the title or author, use your reader's Document Properties, or a command-line tool such as `exiftool -Title="..." file.pdf`. It is worth a look before sending a file out: metadata often still carries the original author's name and the software it was made with.

The page count differs from what I see in my reader.

If your reader shows a different count, the PDF probably uses page labels: the reader follows the labels defined in the file (roman numerals i, ii for a preface, then the body restarting at 1), while this reports the physical page count — how many pages the file really contains. Printing, splitting and merging all care about the physical count.

Is the file uploaded?

No. Parsing means reading the file's structure in local memory with no network requests, and it keeps working offline.
