Edit PDF files
Crop pages, add page numbers and apply watermarks.
These tools change what appears on the page: visible margins, added numbering or a stamped watermark. They are page-level edits, not full text editing.

FAQ
- Can I edit the existing text inside a PDF?
- No. These tools add content on top of pages or change the visible page area. Rewriting existing paragraphs would require rebuilding the original layout and fonts, which PDFYoga does not do.
- Does cropping delete the content outside the box?
- Cropping changes the visible page area rather than erasing objects, which is how PDF cropping works everywhere. Do not rely on it to hide sensitive information.
- Can watermarks and page numbers use Chinese characters?
- Yes. Non-Latin text is rendered with your system fonts and stamped as a transparent image, so Chinese, Japanese and Korean text appears correctly without downloading huge font files.
- Can I control where the watermark or number sits?
- Yes. You can set position, margin, opacity, rotation, font size and the number format before generating the file, and preview the result before downloading.
