How to edit a PDF in PDF Gain
After upload, your PDF opens in a browser workspace with page previews, editing tools, formatting controls, and export options ready to use.
01
Upload your document
Drop a PDF into the upload area or choose a file. PDF Gain prepares the pages, fonts, and editable text when the file allows it.
02
Select the right editing tool
Use Edit Text for existing text, Add Text for new copy, or switch to Highlight, Draw, Shapes, and Manage Pages from the editor rail.
03
Make changes directly on the page
Click the item you want to change, then adjust fonts, size, color, alignment, opacity, or page order in the settings panels.
04
Save and export the finished PDF
Save your work, then use Export to download the edited PDF or export pages as PNG, JPEG, or WebP.
Editor tools for PDF changes
Add new content
Place new text, highlights, freehand drawings, and shapes anywhere on the document.
Manage pages
Reorder, rotate, duplicate, delete, insert blank pages, or import pages from another PDF.

Download a final PDF or turn pages into PNG, JPEG, or WebP images when you need them outside a PDF.
