The Best Free OCR Tools in 2026, Compared Honestly
A comparison of free OCR tools with the limits each one actually publishes — hourly caps, file sizes, language counts and where your file goes. Written by one of the tools being compared, and saying so.
How Small Can Text Be Before OCR Fails? A Measurement
165 Tesseract.js recognition runs across three typefaces and eleven sizes, measuring character accuracy against capital-letter height. Perfect recognition arrives at 9-14 pixels, not the 30-40 usually quoted, and the collapse happens at 4-6.
Text Inside Images: Getting Alt Text and Accessibility Right
Putting words in an image hides them from screen readers and search engines. Here's how to write alt text that works, and when not to use a text image at all.
Is It Safe to Upload Documents to Online OCR? What to Use Instead
For a public screenshot, yes. For a payslip, ID or contract, no. Four ways to run OCR without uploading — in the browser, on macOS, on Windows, offline — and a one-minute test for checking any tool’s claim.
Making Flashcards and Classroom Materials from a Word List
A teacher-friendly workflow for turning vocabulary lists into image flashcards for Anki, Quizlet and printable worksheets, without any design software.
12 Ways to Improve OCR Accuracy on Difficult Images
Concrete fixes for bad OCR output: resolution thresholds, contrast, skew, tables, screenshots versus photos, and knowing when an image is simply not worth OCRing.
Batch-Generating Hundreds of Images from a Text List
Turn a list into hundreds of individual PNGs in one pass: name tags, price labels, flashcards and subtitle frames, plus the file-naming traps to avoid.
Making Your Own Text Watermark for Free
Build a reusable text watermark with a transparent background, then place it so it survives cropping and screenshots without ruining your photo.
How Transparent Backgrounds Actually Work (And When to Use Them)
The alpha channel explained without jargon: why transparent PNGs sometimes show ugly white fringes, and how to avoid it when overlaying text on photos and video.
PNG, JPG, or WebP? Choosing the Right Format for Text Images
Why text images look terrible as JPG, and what 29 measured samples say about the rest: lossless WebP saves a median 28% over PNG, JPEG wins on every real screenshot, and a browser-exported PNG is a median 2.1x larger than it needs to be.
Image Sizes for Social Media: A Reference That Stays Current
Current per-platform image dimensions with links to each platform’s own published spec, plus the safe-area and compression rules that decide whether text stays readable.
Typography for Text Images: Sizing, Pairing and Spacing
Choosing and setting type for images rather than screens: pixel sizing rather than points, measure limits, line-height ratios, and which font pairings survive downscaling.
Color Theory for Text Images: Contrast First, Harmony Second
Colour choices for images that carry words. WCAG contrast thresholds, why the colour wheel matters less than luminance, and palettes that survive compression and colour blindness.
Creative Image Merging: Design Tips and Tricks
Composition rules that make a merged image look deliberate rather than pasted: grid maths, alignment, spacing ratios, and the specific canvas sizes each layout needs.
Understanding OCR: Convert Images to Text Like a Pro
How optical character recognition actually works, stage by stage — from binarization and deskewing through to language models — and what each stage means for your results.
Complete Guide to Converting Text to Images
A practical walkthrough of turning text into image files: when it helps, when it hurts, the contrast and sizing numbers that matter, and the per-platform dimensions worth memorising.
