What is this tool?
A full PDF editor that runs entirely in your browser. Merge multiple PDFs into one, split by range or every N pages, rotate individual pages, reorder by dragging thumbnails, delete pages, and compress with three quality levels.
Reader mode adds movable, resizable elements on top of each page: text annotations, rotated watermarks, and hand-drawn signatures. Position them where you want them, then bake them into the PDF and download — everything happens on your device.
Why it's different
- Nothing is uploaded — every operation runs locally
- Merge, split, rotate, reorder, delete, and compress in one tool
- Drag-to-reorder page thumbnails
- Live watermark preview with adjustable angle and opacity
- Draw signatures with a real pen pad
- Works offline after the first page load
Frequently asked questions
Is there a page or file-size limit?
No hard limit. PDFs up to roughly 50 MB process smoothly. Larger files depend on your device's available memory, since nothing is uploaded to a server.
Does compression reduce quality?
Compression re-saves the PDF with compressed object streams — it reduces structural overhead, not the images inside. Visual quality stays the same. Higher compression means a smaller file with the same visuals.
Can I sign a PDF without printing it?
Yes. Open Sign in the reader sidebar, draw your signature on the pen pad, and place it on any page. Drag and resize it exactly where you want it before baking it in.
Can I watermark every page at once?
Yes. Turn on Apply to all pages in the reader bar before placing the watermark. It will appear on every selected page at the same position and angle.
Are my PDFs private?
Completely. Nothing is uploaded. Open your browser's developer tools, watch the Network tab, and you'll see zero outbound requests while you work. This is verifiable, not a marketing claim.
What about password-protected PDFs?
A password-protected PDF cannot be opened client-side without the password. If you know the password, decrypt it first in a dedicated tool, then bring the unlocked file here.
