Question 4

What features are available?

Accepted Answer

Nanodoc offers a comprehensive set of PDF editing features including: combining multiple PDFs into one document, stitching PDF pages onto a single canvas (remove white backgrounds or erase SVG elements, then arrange, resize, rotate, and export as one PDF), deleting unwanted pages, extracting specific pages, adding text annotations, highlighting text with customizable colors, and redacting sensitive information. All features are available for free.

Question 5

What is the Stitch PDFs feature?

Accepted Answer

Stitch PDFs lets you combine multiple PDF pages onto one canvas and export them as a single PDF. When adding pages, you can remove white backgrounds so only the content (text, lines, graphics) is imported. On the canvas you can also erase individual elements by clicking on lines, shapes, or SVG-style content. Drag to position, resize, and rotate each tile, snap to edges, use alignment tools, and optionally crop. When you're done, download the stitched PDF or open it in the editor. It's ideal for building custom layouts (e.g. construction plan sets) or merging scanned pages into one sheet.

Question 6

How do I use the PDF editor?

Accepted Answer

Using Nanodoc is simple! Click the 'Start Editing PDFs Now' button on the home page, then either drag and drop a PDF file into the editor or click 'Browse Files' to select a PDF from your computer. Once your PDF is loaded, you can use the toolbar on the right to access all editing features.
