NotebookLM Makes the Slides. Here Is How to Actually Edit Them.
Short answer: NotebookLM already creates the deck for you. The catch is the only export is a PDF where every slide is a flat image, so PowerPoint sees pictures instead of text. DeckEdit is the second step: drop that PDF in, get back a real .pptx where every heading and bullet is a normal, editable text box. The whole flow takes about three minutes and runs entirely in your browser. This guide is honest about which tool does what: NotebookLM owns the creation, DeckEdit owns the conversion to editable.
Wait, NotebookLM Already Makes the PowerPoint?
Yes. NotebookLM generates a slide deck of up to 20 slides directly from the sources you upload (PDFs, docs, web pages, video transcripts). It writes the cover, the section structure, and the summary for you, grounded in your sources rather than the open web. You do not need DeckEdit, or any other tool, to create the deck itself.
Where the workflow breaks is the export. NotebookLM only lets you download the deck as a PDF, and that PDF contains rendered images of each slide rather than selectable text. Open it in PowerPoint or Google Slides and you cannot click a heading to retype it. That is the gap DeckEdit fills, and the only reason this page exists. If you just want the deck to look at, you can stop after NotebookLM.
The Honest Five Step Workflow
Step 1. Open NotebookLM and add your sources
Sign in at notebooklm.google.com, create a new notebook, and upload the documents you want the deck to be based on. PDFs, Google Docs, plain text, web URLs, and YouTube transcripts all work. Better sources produce better slides, so curate the inputs rather than dumping everything you have.
Step 2. Let NotebookLM generate the deck
In the Studio panel on the right, choose Slides. NotebookLM drafts a deck of up to 20 slides grounded in your sources, with a title slide, structured sections, and a closing summary. Generation takes one to two minutes. Regenerate or refine here if the outline is wrong. Fixing structure inside NotebookLM is faster than fixing it later in PowerPoint.
Step 3. Download the PDF (and notice it is not editable)
Use NotebookLM's download option to save the deck as a PDF. Open the PDF in any viewer and try to select a heading. You cannot. Every slide is a single flat image embedded in the page. That is not a NotebookLM bug, it is the only export format available today. Keep the file on your machine. The next step is what makes it actually editable.
Step 4. Drop the PDF into DeckEdit to make it editable
Open deckedit.com and drop the PDF onto the upload zone. Browser based OCR detects every text region on every slide and reconstructs each one as a real .pptx text box, with font size, alignment, and position preserved. Nothing leaves your device. A 20 slide deck typically converts in 30 to 60 seconds on a modern laptop.
Step 5. Edit and export the real .pptx
Download the .pptx and open it in PowerPoint, Keynote, or Google Slides. Every text element is now selectable and editable, so you can rewrite copy, restyle headings, swap fonts, and reorder slides like any normal deck. If you prefer to stay in the browser, DeckEdit also includes an inline editor where you can fix typos and adjust formatting before exporting.
Why You Need a Second Tool at All
NotebookLM renders each slide as a flat image and embeds those images in the PDF. This is fine for viewing or printing, but PowerPoint and Google Slides treat the result as a picture, not as text. You cannot click a heading and retype it, fonts and colors do not respond, and ordinary slide tools simply do not apply.
DeckEdit reverses that with on device optical character recognition. It identifies every text region, reads the characters, then writes them back as real PowerPoint text frames at the same coordinates. The output is a normal .pptx file, indistinguishable from one authored in PowerPoint by hand. That is the only thing DeckEdit does, and it is the only step NotebookLM cannot do for you.
Tips for Better Results
- Curate your sources. NotebookLM grounds every slide in the documents you provide, so a focused source list produces a focused deck.
- Keep decks under 20 slides. That is NotebookLM's hard limit per generation. For longer presentations, generate two decks and convert each.
- Prefer light backgrounds. NotebookLM's default theme converts cleanly. Heavy decorative themes can reduce OCR accuracy on small text.
- Fix the outline before you convert. Regenerate inside NotebookLM if the structure is wrong. Restructuring after the .pptx exists is doable but slower than redoing the outline upstream.
- Convert locally. DeckEdit runs in your browser with no upload, so confidential source material stays on your machine end to end.
Privacy and Speed
DeckEdit's conversion runs entirely client side. The PDF you generated in NotebookLM is processed by your own browser using WebGPU or WebAssembly. There is no upload, no account, no queue, and no server side log of your file. On a modern laptop a 20 slide NotebookLM deck typically converts in under a minute.
