Frequently Asked Questions
PDF geometry strictly defines 1 point as 1/72 of an international inch (25.4 mm). The conversion math calculates measurements using standard engineering constants, ensuring complete geometric precision down to two decimal places across points, millimeters, centimeters, and inches without rounding discrepancies.
No document ever leaves your computer or mobile device. Parsing, metadata extraction, dimension matching, and thumbnail rendering occur entirely inside your browser's local sandbox using client-side Web Workers. Zero file data or metadata packets are transmitted across external networks.
The parser scans every single page container inside the PDF tree upon load. If any pages differ in aspect ratio, width, height, or portrait-landscape rotation, an alert banner notifies you immediately while the page selector lets you inspect individual pages.
Files protected with permissions or read restrictions are flagged accordingly. If a PDF requires an open password, the tool detects the security dictionary and notifies you that full metadata extraction requires unlocking the file with appropriate credentials.
The application relies on memory-safe ArrayBuffers and streams metadata dictionaries on demand without loading all uncompressed page bitmaps simultaneously. Canvas previews are released immediately when switching or resetting files, keeping memory overhead light even on mobile browsers.
