How to Edit Unselectable Text in PDF and NotebookLM Slides
A step-by-step guide to editing text that can't be selected, copied, or modified in PDFs.
Why Can't You Select Text in Some PDFs?
You've probably encountered this frustration: you open a PDF, try to select some text to copy it, and nothing happens. The cursor doesn't highlight anything. The text looks perfectly normal, but it behaves like an image.
This happens because many PDFs — especially those exported from Google NotebookLM, Canva, Gamma, and other AI slide generators — render text as rasterized images rather than selectable text layers. The PDF contains pixel data, not character data. Your PDF viewer sees a picture of text, not actual text.
The Solution: Local AI OCR
Optical Character Recognition (OCR) can read the pixels in your PDF and reconstruct the text content. DeckEdit runs OCR entirely in your browser using state-of-the-art AI models that process your files locally without uploading them to any server.
Step 1: Upload Your PDF or Image
Open DeckEdit and drag your PDF or image file into the upload zone. DeckEdit supports PDF, PNG, JPEG, GIF, and WebP files up to 30MB and 50 pages. No account or registration is required.
Step 2: Choose Your Mode
DeckEdit offers two modes depending on your goal. PPTX Conversion mode creates an editable PowerPoint file where every detected text element becomes a real text box you can click and edit. Image PDF Edit mode lets you click directly on detected text regions to modify or delete them in-place, then export in the original format.
Step 3: Download Your Editable File
After processing, download your file. In PPTX mode, you get a PowerPoint presentation with editable text boxes and the original slide background preserved. In Edit mode, you get a clean PDF or image with your modifications applied.
