PDF Tools
Your PDFs never leave your browser — no uploads, no watermarks, no signup.
PDF Merge
Combine multiple PDFs into one. Drag in your files, drag them into the order you want, and download the merged result. No file count limit, no size limit beyond what your browser can handle.
Open Merge ToolPDF Split
Pull out specific pages or page ranges from a PDF. Type something like 1-3, 5, 8-end and get either one combined PDF or a ZIP with each range as its own file.
PDF Rotate
Rotate any page (or every page) by 90, 180, or 270 degrees. Live thumbnail preview so you can see exactly which pages are sideways before saving.
Open Rotate ToolNeed a desktop PDF app?
These browser tools cover merge, split, and rotate without uploading anything. For viewing, annotating, or deeper editing offline, here are well-established, free, open-source apps worth installing — all actively maintained, no trial nags, no watermarks.
SumatraPDF
Featherweight, instant-open viewer for PDF, ePub, CBR, and XPS. Tiny install and a portable build with no setup.
Okular
KDE's document viewer with solid annotation and markup — highlights, notes, stamps, and inline comments you can save back to the file.
Xournal++
Annotate, highlight, handwrite, and fill in forms. Great with a stylus or tablet for signing and marking up documents.
LibreOffice Draw
Part of the LibreOffice suite. Opens a PDF as an editable document so you can change the actual text, images, and layout.
PDF Arranger
Visual page management — merge, split, rotate, crop, and reorder pages by dragging thumbnails. The desktop counterpart to the tools here.
Stirling-PDF
A full Acrobat-style suite with 50+ tools — convert, sign, redact, OCR, and more. Run it locally via Docker or the desktop build; nothing leaves your machine.
