How it works
Append every page of each selected unencrypted PDF in selection order.
Input definitions
- Select PDF files (2–10)
- Select supported files from your device.
A worked example
File outputs depend on the selected document. PDF extraction copies the inclusive page range; rotation applies the chosen clockwise angle. A 2400 × 1600 image fitted to 1200 × 1200 becomes 1200 × 800.
Assumptions & limits
Maximum 10 MiB per file, 20 MiB total, 10 PDF inputs, 200 PDF pages total, or 24 megapixels per image. Encrypted PDFs, forms, signatures and accessibility structure are not preserved or supported. Image orientation uses browser decoding; JPEG transparency becomes white. Cancel terminates processing; files stay on your device.
