XenPDF
A Windows desktop utility for working with PDF files. Six tools in one app. One-time purchase. Runs on Windows 10 and later.
What it does
Add PDF files, put them in the order you want, and save the result as a new combined PDF. Bookmarks from every source can be kept and rebuilt in the merged outline. Source files are not modified.
Type a page range or click pages to pick them, then extract or delete that selection. Output is saved as a new file. The original is not modified.
Encrypt a PDF with AES-256, or RC4-128 for older readers. Restrict printing, copying, or editing. Unlock a file or change its password in one step.
Reorder and rotate pages with a thumbnail of each page in front of you. Rotation is written explicitly, so resetting a page back to zero sticks.
Turn PNG, JPEG, WebP, BMP, GIF and TIFF files into a single PDF. Drag to reorder, and rotate any image without re-encoding it. Transparent pixels are composited onto white.
Stamp text across one PDF or a whole batch. One or two lines, with size, opacity and angle, placed on a 3×3 position grid with an adjustable margin. A live preview shows the result on the real page shape before you save.
Technical details
- All operations run locally using lopdf. No files are sent anywhere.
- Encryption is AES-256 by default. RC4-128 stays available for readers that cannot open AES-256.
- XenPDF generates a random owner password. Printing, copying and editing permissions depend on support in the PDF reader; they do not prevent every application from accessing the document's content. The opening password itself is real AES-256 encryption.
- Output is always written to a new file. The input is never overwritten.
- Merge copies page objects instead of re-encoding them, so quality is untouched and large merges stay fast.
- Slice operates on page indices. It does not reflow or re-render content.
- A built-in preview renders pages with PDFium and can send the open file straight into any of the six tools.
- Long operations run in the background, so the window stays responsive on large files.
- The program imports no networking library at all — the local-only claim is verifiable from the executable itself.
- The Store download is 7.4 MB. Installed, the program and its PDFium page renderer take about 14.5 MB.
What it does not do
- Edit text or images inside a PDF
- Perform OCR
- Fill or create forms
- Compress or optimise file size
- Read EXIF orientation from images — use the per-image rotate button instead
- Render watermark text outside the Latin-1 character set
