OCR: How to Extract Text from Images, Videos, and PDFs (2026 Guide)
I have one rule: don’t retype what you can copy.
But the web is full of “uncopyable” text:
- text inside images
- text inside YouTube/course video frames
- sites that block selection/right-click
- scanned PDFs (you can see it, but you can’t select it)
That’s what OCR (Optical Character Recognition) is for: turning what you see on screen into copyable text.
This guide explains when to use OCR, how to get better accuracy, and how to handle tables/code—using Eyesme Extension as the example workflow.
When to use OCR (and when not to)
Before you “OCR everything,” decide your goal:
- Copy a paragraph/quote → OCR (plain text)
- Convert a table into editable data → table extraction (CSV/JSON)
- Extract runnable code → code extraction (keep indentation)
- Understand meaning (charts/UI/clauses/errors) → screenshot analysis

OCR workflow with Eyesme (5 steps)
Step 1: Capture the smallest useful area
OCR hates noise. Crop tightly to the text you need.
Step 2: Clarity beats “better models”
- if the font is small, zoom in and re-capture
- if the frame is blurry, pause on a clearer moment
- avoid low-contrast text (light gray on gray)
Step 3: Specify the output format
Same image, different useful formats:
- plain text (paragraphs/quotes)
- line-by-line list (steps/items)
- key-value pairs (serial numbers/config fields)
Step 4: Quick validation (10 seconds)
Check common confusions:
- 0/O, 1/I/l
- missing dots/slashes in URLs/emails
- commas/decimal points in numbers
Step 5: If you need meaning, follow up
OCR gives you text. Then ask for understanding:
- “Summarize this in 3 bullets.”
- “Explain the key terms with examples.”
- “Convert this config into a runnable command.”
