Page Operators → JSON

Analyze the content streams of a PDF and export the operators/operands (TJ/Tj, Do, cm, q/Q…) page by page in JSON — locally in the browser.

Import a PDF

No data is sent to a server: everything is done in your browser.

Debug text renderingUnderstand why text does not appear, is reversed, or is in the wrong place (matrices, clipping, order).
Identify displayed imagesIdentify which resources (XObject) are drawn on a page and in what order (Do operator).
Technical analysis / reverseStudy a PDF generated by a third-party tool to understand its content structure (ops and parameters).

A JSON per page listing the operators and their operands (execution order preserved).

Actionable information to write detection rules (e.g., pages without text, presence of transformations, etc.).

Very technical output: it reflects the PDF description language, not a "human" representation of the content.
Streams may be compressed/filtered: extraction depends on the engine's ability to decode them.
For large PDFs, the export can be bulky: target a page/range if possible.

Does this replace text extraction?

No. It is a debugging tool: it shows low-level operations, not the reconstructed text.

I see a lot of "q" and "Q", is that normal?

Yes: these are very frequent graphic state (stack) saves/restorations.

What does "cm" stand for?

It is a transformation (matrix) applied to the coordinate system: often the cause of unexpected positions/rotations.

Debug tip: look for sequences around "Tj/TJ" (text) and "Do" (XObject) to understand the actual display order on the page.
