All-in-One PDF Editor

PDF · EDITOR

Open several PDFs and photos at once, then reorder, rotate, delete, duplicate or add blank pages, stamp page numbers or a watermark, and save as one PDF, split files or images.

Your files are processed right here in your browser. Nothing is uploaded or stored on a server.pdf-lib (MIT) · pdf.js (Apache-2.0) · Noto Sans KR (OFL)

Good to know. Very large PDFs or files with many pages may be slow or run out of browser memory. Page numbers and watermarks appear only in the saved file. Password-protected PDFs can't be opened.

HOW TO

How to use

  1. Drop several PDFs and JPG, PNG or WebP photos at once, or click Choose files. Every page appears in one thumbnail grid.
  2. Drag thumbnails to reorder. Click pages to select them (Shift for a run), then rotate, duplicate, delete or insert blank pages with the toolbar. Ctrl+Z undoes.
  3. Open Decorate to add page numbers (position, format, start number) or a text watermark to every page or only the selected ones.
  4. Pick how to save: one PDF, selected pages only, split every N pages or each page into a ZIP, or images (PNG/JPG) in a ZIP.

FAQ

FAQ

Are my files uploaded?

No. Opening, editing and saving all happen inside your browser. Nothing is sent to a server.

Can I mix photos and PDFs?

Yes. Each JPG, PNG or WebP image becomes a page sized to fit A4 and can be moved between PDF pages like any other page.

Does the watermark support non-Latin text such as Korean?

Yes. When the text needs it, a Noto Sans KR subset is embedded in the PDF so the watermark shows correctly anywhere.

Can I open password-protected PDFs?

No. PDFs with a password or security settings are not opened, and this tool does not remove protection.
