How to Extract and Save Slides from Udemy Courses

The Challenge of Note-Taking on Udemy

Udemy is a fantastic platform for learning practical skills, from programming to graphic design. While some instructors provide downloadable resources, many do not include the raw slide decks they use in their video presentations. If you want to review the slides later, your only option is to manually pause the video, take a screenshot, and then get back to watching — a process that completely ruins your learning momentum.

SlideSieve is the perfect tool to automate this process. It runs entirely inside your Chrome browser and captures Udemy slides automatically as you watch, with zero manual effort.

Step-by-Step Guide

1. Install SlideSieve

Ensure you have the SlideSieve Chrome Extension installed in your browser. Pin it to your Chrome toolbar so you can quickly access the Side Panel while watching lectures.

2. Open Your Udemy Course

Navigate to your Udemy course and open any video lecture that contains presentation slides. SlideSieve integrates directly with Udemy's video player.

3. Start the Capture

Before pressing play, click the prominent Start Auto Capture button located on the SlideSieve floating toolbar directly under the video player. SlideSieve will automatically read the Udemy page and organize your capture session by the specific course name and lesson you are viewing — so all your slides are neatly labeled and separated by lesson. Now you can hit play, and the extension will capture every slide from the very beginning!

4. Let the Algorithm Work

As you watch the lecture, SlideSieve operates silently in the background. It uses computer vision to analyze each video frame and make a real-time decision: is this a slide, or is this the instructor on camera?

It automatically ignores frames where the instructor is on camera, capturing only the actual slides as they appear. Dark transition screens between sections are also skipped. The result is a clean set of slide captures — nothing more, nothing less.

5. Review Your Captures

After the lecture, open the SlideSieve side panel. Browse your slides in Grid View for a compact overview, or switch to List View to read the content at a larger size. You can delete any unwanted frames by hovering over the thumbnail and clicking the × button.

6. Export to PDF

When the video is finished, use the Export button to instantly generate a local PDF file containing all your Udemy slides, perfectly formatted and preserving the original aspect ratio of every frame. You can also export as individual image files (ZIP) if preferred.

Pro Tips for Udemy

• Start before you press play. Click "Start Auto Capture" before hitting play on the video. This way, SlideSieve is watching from the very first second.
• Use manual snap for whiteboards. Some Udemy instructors draw on digital whiteboards or use on-screen coding demos. These may not be detected as "slides," but you can instantly capture any frame with the Ctrl + Shift + 9 keyboard shortcut.
• Jump between lessons freely. SlideSieve tracks lesson changes based on the Udemy URL. When you switch to the next lesson, it automatically starts a fresh capture session under the correct lesson name.
• Your slides are always saved. Captured slides are stored in your browser's local storage (IndexedDB) and are not deleted between sessions. You can export them any time, even days after the lecture.
