Introduction to NotebookLM Presentation Editor
After clicking the link above to access the NotebookLM presentation editor, first log in to your Google account.
Go to NotebookLM presentation editor
After logging in, you can upload your NotebookLM presentation PDF file, supporting up to 20 pages. It also supports JPG, PNG, and GIF file formats, which means if you want to edit the text in images generated by NotebookLM, you can also use this tool to do so:
Once the upload is complete, you’ll see each slide of your presentation PDF below. They haven’t been converted to editable text yet, which means you can simply select the pages you want to modify:
After finding the slide image you need to edit, click “Start Analysis” on the screen:
You will see that the text on the image is converted into individual blocks, and then you can directly click on the text block you want to modify to edit it:
As shown in the figure below, when I click on “Your thoughts are always faster than typing” at the top, this text will appear in the recognition results section on the right:
I changed it to “Your thoughts, your typing speed just can’t keep up?” Below that, you can also adjust whether to keep it bold and the text color (I changed it to red). Once you’re done, click “Apply Changes” below:
Then you will see the original text change to the content you modified. One thing to note here: you can only modify the text content and cannot move where the text is placed.
Below is a toggle button for switching between “Original” and “Edited,” making it easy to compare the differences.
Next, let’s analyze the other slide images you need to modify:
Once you’ve finished editing, you can click “Export PDF” at the top to get your newly modified presentation PDF. It also supports removing the NotebookLM watermark, though in my testing, this feature still has room for optimization—for example, some screens may cause the images in the slides to become blurry, and images that have been analyzed won’t have their watermarks removed.
After the export is complete, a “Download PDF” button will appear. Click it to download.
After downloading, remember to check if the content shows “modified” status.
Additionally, the font of edited text may differ slightly from the original font. Take this sentence in the image below: “Any applications you use are supported, from mail,” which I edited, while the next part “chat to code editors” I didn’t modify, so you can clearly see these two fonts look quite different:
