How Optical Character Recognition (OCR) Works In Your Browser
Optical Character Recognition (OCR) utilizes neural networks to detect letterforms and words inside digital images. ToolStackly executes the entire recognition model locally using WebAssembly, meaning confidential photos never leave your device.
Tips for the Best Recognition Accuracy
- High Contrast: Black text on a white background yields 99%+ accuracy.
- Even Lighting: Avoid heavy shadows or glossy glare on physical paper scans.
- Straight Alignment: Orient text horizontally for optimal word segmentation.
