What these tools support
Works with ordinary, unencrypted PDFs and JPEG/PNG images. Password-protected PDFs, interactive forms, and signed documents are not supported. Make an unsigned, flattened copy in the original application first if appropriate. PDF portfolios, attachments, bookmarks, and document-level features are not preserved when pages are copied.
Extract / reorder accepts entries such as 5-3, 1, 1 to reverse a range or repeat a page. Other page selections do not repeat pages. Splitting creates individual download links (up to 100 pages), so your browser never has to allow automatic bulk downloads. This tool does not edit existing text, perform OCR, compress PDFs, or convert Word files.
All processing uses the locally included pdf-lib 1.17.1 library (MIT license). Files stay in this browser tab and are not saved to site storage. Large or complex documents may exceed your device's memory; use smaller batches.
