Annotation Techniques That Aid Studying
Highlight key definitions in one colour, supporting evidence in another. Add text comments to summarise a paragraph in your own words. Underline terms that appear in exam questions. Use sticky notes to flag sections to revisit. These active reading strategies improve recall significantly.
How to Annotate a PDF
Open fixmypdf.in/tools/add-comments. Upload your reading or lecture notes PDF. Use the toolbar to select highlight colour, text comment, or underline. Click and drag over text to highlight. Click to add sticky notes. Download the annotated PDF when done.
Annotating Lecture Slides
Upload the lecture slide PDF. Add text notes next to each slide summarising what the lecturer said (from your memory or audio recording). This creates an integrated study document far more useful than raw slides.
Colour-Coding for Different Subjects or Themes
Use yellow for definitions, green for examples, pink for exam-relevant content, blue for your own questions. Consistent colour-coding across all your PDFs makes revision faster — scan for yellow to review definitions first.
Annotating on iPhone and Android
Open Safari or Chrome on your phone, navigate to fixmypdf.in/tools/add-comments, upload from Files or Google Drive, annotate using touch, and download. Apple Pencil and Samsung S Pen are supported for drawing annotations.
Sharing Annotated PDFs with Study Groups
Download your annotated PDF and share via Google Drive, WhatsApp, or email. Classmates can see your annotations and build on them, or compare with their own highlighted versions.
Remove Annotations Later if Needed
If you need a clean copy for submission after studying, use Remove Annotations to strip all highlights and comments, leaving the original document intact.
