Frequently Asked Questions

Common questions about the free online pdf object counter.

It scans the raw bytes of the file and tallies indirect objects, streams, fonts, images and pages it can see.
It is a numbered entry in the file such as 12 0 obj, which holds a dictionary, an array or a stream.
PDFs that pack objects into compressed object streams hide those entries from a plain text scan.
It is a newer way of storing the object index as a compressed stream instead of a plain xref table.
The tool counts font dictionaries, so the same typeface used with several sizes can appear more than once.
Not always. Files with many images or embedded fonts have more objects but often open quickly.
No. Everything is counted in your browser and the file never leaves your device.
It reads PDF 1.x files of any version, limited only by whether the internal objects are compressed.
Yes, the counter is completely free with no sign-up and no usage limits.
