Frequently Asked Questions (FAQ)
No. AllThatConverter processes all character recognition entirely within your browser's local sandbox via WebAssembly. Neither your image files nor the converted text strings are ever transmitted to or stored on external servers.
Yes. For mixed-language materials such as bilingual manuals or academic papers containing both English and Korean/Japanese, simply select all relevant language checkboxes simultaneously to optimize detection accuracy.
The OCR model is specifically trained on printed typography and screen fonts. While legible handwriting may be partially detected, accuracy declines with cursive scripts, heavy tilt, low lighting, or blur. For best results, use well-lit, high-contrast, front-facing captures.
On your first use of a specific language, your browser downloads that language's trained neural network model directly into local browser cache. Once cached, subsequent recognition runs commence instantly without redownloading.
Ensure high image resolution and strong contrast between text and background. If the image has complex borders or multiple columns, use our Crop Image tool first to isolate just the text passage before running OCR.
