Merge, split and convert PDF files
PDF files are the standard way to share documents that must look the same everywhere, but changing them can be awkward. These tools handle the jobs people need most, with no software to install and no account to create.
Use Merge PDF to join several files into one, and Split PDF to extract pages or cut a long document into parts. PDF to Images saves the pages as PNG or JPG pictures at the resolution you choose, and Text to PDF turns typed or pasted text into a clean PDF with the page size, font and margins you pick. Every tool works in your browser, so your documents are never uploaded anywhere.
NinjaFunction's Merge PDF joins several PDF files into one document. Add your files, use the arrows to put them in the order you want, and click Merge. The pages are copied exactly as they are, so text, images and layout stay the same. You can merge up to 20 files at a time, and everything is done in your browser, so your PDFs are never uploaded to a server.
NinjaFunction's Split PDF takes a PDF apart in three ways. Extract the pages you pick into one new PDF, split by ranges such as 1-3 and 4-6 so each range becomes its own file, or cut the document into parts of a set number of pages. You see exactly which files you will get before you click. Download them one by one or as a ZIP. Everything is done in your browser, so your PDF is never uploaded to a server.
NinjaFunction's PDF to Images saves the pages of a PDF as PNG or JPG pictures. Choose all pages or just the ones you need, pick a resolution from 72 to 300 DPI, and see each page appear as it is finished. Download single images or all of them as a ZIP. The pages are drawn in your browser, so your PDF is never uploaded to a server.
NinjaFunction's Text to PDF makes a PDF from any text you type, paste or open from a .txt file. Add an optional title, choose A4 or Letter, a font, text size, margins and line spacing, and switch page numbers on or off. The PDF contains real text that can be selected and searched, and you see a preview before you download. It is made in your browser, so your text is never uploaded to a server.
NinjaFunction's Image to PDF turns your pictures into a single PDF with one picture on each page. Add up to 30 images, put them in order, choose A4, Letter or a page that matches each image, set the page direction, margin and quality, and download the file. The PDF is made in your browser, so your images are never uploaded to a server.
NinjaFunction's PDF Watermark adds a text or picture watermark to your PDF in the browser. Type text such as CONFIDENTIAL or DRAFT, or add a PNG or JPG logo, then choose the position (centre, repeated, top or bottom), size, colour, strength, turn and the pages to mark. Rotated pages are handled. Your file is never uploaded.
NinjaFunction's PDF Page Numbers adds numbers to the pages of a PDF in your browser. Choose a look such as 1, Page 1, Page 1 of 10 or 1 / 10, Arabic or Roman numerals, one of six positions, the first number, the text size, colour and distance from the edge, skip the cover page, and number the outer edge for two-sided printing. Your file is never uploaded.
NinjaFunction's PDF Compressor makes a PDF smaller in your browser. The Recommended and Strong levels shrink the pictures inside the file and keep the text sharp and selectable. The Maximum level turns each page into a picture for the smallest file. You see the size before and after, and if the file cannot be made smaller you are told and given no bigger file. Your PDF is never uploaded.

No. All of the PDF tools work in your browser, so your files stay on your device. Nothing is sent or stored, and closing the page removes everything.
Each PDF can be up to 80 MB. Because the work is done on your own device, very large files can be slow, and the speed depends on your computer or phone.
Not directly. A PDF with a password cannot be read until the password is removed. Open it with the password in a PDF viewer, save an unprotected copy, and use that copy here.
