Can I make image occlusion cards from a PDF?
Yes. You can turn a PDF into image occlusion cards by pulling the labeled diagrams out of the file and masking each label. Most occlusion tools want one pasted image, so you crop the figure first. StudyPDF skips that: upload the whole PDF and it finds the diagrams in your slides and masks them for you.

In more detail
The slow way is manual. You open the PDF, screenshot or crop the diagram you want, paste it into Anki or an occlusion tool, then draw a mask over each label. For a lecture with several figures that is a lot of cropping before you even start studying.
The faster way reads the PDF directly. Instead of one image, you give it the file, it locates the labeled figures across the pages, and it masks the labels on each one. You get cards from a slide deck or a textbook chapter without cropping anything by hand.
This matters because the diagram you need is almost always trapped inside a bigger document, your lecture slides or a scanned page, not sitting on your desktop as a clean image.
Step by step
- 1
Upload the PDF, slides, scan, or photo set.
- 2
Let the tool find the labeled diagrams inside the file.
- 3
It masks each label on every diagram it finds.
- 4
Review the masks, then export to Anki or PDF.
How StudyPDF helps
StudyPDF is built for this. Upload a PDF and StudyPDF extracts the labeled diagrams from your slides, masks the labels, and lets you export native Anki image occlusion on Pro, all without cropping a single figure. It also reads scans and photos, so a snapshot of a textbook page works the same way.

More questions
Does it work with scanned PDFs and photos?
Yes. StudyPDF reads scanned pages and photos with OCR, so a phone snapshot of a labeled diagram in your textbook can become occlusion cards just like a digital slide.
What if my PDF has many diagrams?
It handles the whole file. StudyPDF finds the labeled figures across all the pages and makes a masked card for each, so one upload can produce a full set of diagram cards.
