PDF merge, extract, rotate, and crop run in this browser.
These tools read the PDF you choose, process it in a Worker on this device, and hand you a download. The file is not uploaded to a Trendalyzer processing server. Workflows are in beta — open the downloaded file in an independent reader before you rely on it for sensitive or production work.

How it works
Each operation copies pages from the files you choose into a new PDF using pdf-lib in a Worker. Merge keeps the input order. Extract keeps only the requested page numbers. Rotate writes a /Rotate value. Crop sets the crop box in PDF points. Form fill writes text into standard AcroForm fields and flattens them. There is no OCR and no server round-trip.
Only the workflows below are exposed while broader conversion, security, OCR, redaction, and repair claims await browser and output-integrity evidence.
