Flashcards are one of the most evidence-backed revision tools in educational psychology. The act of recalling information from a card — rather than passively reading it — significantly improves long-term retention. Digital flashcard images can be used in apps like Anki, printed for physical use, or shared with classmates. At imgresizr.com, you can create flashcard images for any subject, for free.

| Phone screen | 1080×1920px (full screen) |
How to Create Flashcard Images at imgresizr.com
Open imgresizr.com and set dimensions for your chosen flashcard format. For digital flashcards, 1280×720px is a versatile size. Use a clean, uncluttered design: white background with a coloured border or header bar in your subject colour (blue for science, green for biology, red for history, etc.). Use the Caption tool to add the question or term in large, bold text on the "front" design. Create a separate image for the "back" with the answer or definition. Use clear, readable fonts at a large size — flashcards must be scannable at a glance. Export as JPG for digital apps or PNG for print.
Flashcard Effectiveness Tips
- One concept per card — never cram multiple facts onto a single flashcard
- Use the question on one side, answer on the other — the recall effort is what builds memory
- Add images to flashcards where possible — dual-coding (text + image) doubles retention
- Use spaced repetition — review cards at increasing intervals (1 day, 3 days, 7 days, 2 weeks)
- Colour-code by subject or topic for efficient sorting and review sessions
