How to Annotate Lecture Slides on iPad: A UK Student's Guide
19 August 2026
Learn step-by-step how to annotate lecture slides on iPad with Apple Pencil, including the best apps for UK students and export tips.
Set Up Your iPad for Slide Annotation
Before you start annotating, make sure your iPad is configured for a smooth workflow. First, ensure your Apple Pencil is paired and charged – check that Bluetooth is on and attach the pencil to the magnetic connector (or plug in the Lightning version). Then, open your lecture slides in PDF format; most UK university VLEs (like Blackboard or Moodle) let you download PowerPoint as PDF. If your slides are PPTX, use the Files app to export them to PDF so annotations stay stable. Next, adjust your Apple Pencil settings: go to Settings > Apple Pencil and enable 'Only Draw with Apple Pencil' in note-taking apps to avoid accidental marks from your palm. Finally, decide on your annotation app – you can use built-in tools like Markup or dedicated apps like GoodNotes. A screen protector with a paper-like texture can also improve precision, but it's optional.
Use Built-in Markup and Freeform for Quick Annotations
If you don't want a third-party app, iPadOS offers free tools that handle slide annotation well. The simplest method is to open a PDF in the Files app, tap the Markup icon (a pen tip in a circle), and start writing with your Apple Pencil. You can choose from a range of pens, highlighters, and a magnifier tool. Your annotations are saved over the original PDF, and you can share the annotated version via AirDrop or email. Another free option is Freeform, which acts as an endless canvas – you can import slide screenshots and draw around them, but it's less precise for page-by-page annotation. For a more structured approach, Apple's Notes app lets you insert a PDF or photo and annotate directly on it, with the benefit of syncing across iCloud. These tools are great for quick, lightweight markup, but they lack features like handwriting search and organisation folders that power users need.
Choose a Dedicated Annotation App: GoodNotes vs Notability vs PDF Expert
UK students often turn to dedicated apps for richer annotation features. GoodNotes (one-time purchase around £9.99) is a favourite because it recognises handwriting in search, lets you import PDFs as notebooks, and syncs via iCloud. Notability (subscription around £10.99/year) adds audio recording – you can record the lecture while tapping notes, and playback synced to your handwriting. PDF Expert (subscription £9.99/month or one-time) is excellent if you work with multiple PDFs and need smart file management, including connecting to OneDrive or Google Drive. Consider your workflow: if you prefer writing directly on slides and organising them by module, GoodNotes is strong. If you need to record lectures alongside, Notability shines. For a free, robust alternative, try CollaNote. Many UK universities also offer institutional discounts through UNiDAYS, so check before purchasing.
Efficient Techniques: Use Split View and Colour Coding
To annotate effectively, set up Split View so you can view the lecture slides and your note-taking app side-by-side. On iPad, swipe from the bottom to expose the Dock, then drag an app like GoodNotes to the right edge. This lets you see your lecturer's PowerPoint on one side and your annotation app on the other, reducing the need to switch. Use a colour-coding system: red for definitions, blue for exam tips, yellow for examples, and green for questions. This helps when revising later. Also, use the highlighter tool and the lasso tool to compress or move text around. If your lecturer releases slides with blank lines or diagrams you need to recreate, use the image insertion tool to paste a screenshot of the diagram and annotate over it. For maths-heavy subjects, try a stabilising ruler or a math handwriting tool available in GoodNotes 6.
Export, Sync, and Share Your Annotated Slides
Once you've annotated your slides, organisation is key. Most apps auto-sync to cloud storage – GoodNotes and Notability use iCloud, but you can also export to Google Drive, OneDrive, or Dropbox. To share a single annotated slide deck, export as PDF and send via email or a link using the Files app. If you need to submit coursework or show a tutor, make sure the annotations are flattened into the PDF – check the export settings. For a whole module, create a folder per topic and rename files with the lecture date and number. Some UK universities provide Microsoft 365, so you can also upload annotated PDFs to SharePoint or Teams for collaboration with classmates. Remember to back up your original slides and your annotated versions, as losing months of revision notes can be devastating. Use the 'Search' feature in apps to find specific words in your handwriting – a huge timesaver during revision.
FAQ
Yes, but with limitations. PowerPoint for iPad allows you to draw with Apple Pencil using the Draw tab, and your annotations are saved within the PPTX file. However, if you prefer handwriting that isn't tied to text boxes, converting to PDF first is usually better because all apps handle PDFs consistently. Many universities provide slides as PPTX, but exporting to PDF from the PowerPoint app takes seconds and gives you a stable page layout.
