Why This Happens

The PDF trailer (located at the end of the file) is missing or corrupted. The trailer tells readers where the cross-reference table starts and is essential for parsing.

How We Fix It

We scan backward from the end of the file to find the xref table, recalculate offsets, and append a fresh, valid trailer section.

The Problem

Your PDF reader says 'Trailer not found' and refuses to open the document, even though the file looks like it has all your content.

Frequently Asked Questions

What does the PDF trailer contain?

The trailer contains the byte offset of the cross-reference table, the root object reference, the encryption dictionary reference, and the end-of-file marker. Without it, readers can't parse the file structure.

Is the trailer the same as the EOF marker?

The trailer includes the 'startxref' pointer and '%%EOF' marker. A missing trailer means all of this is gone or unreadable.
