What it does: The Image to Text OCR tool extracts Vietnamese and English text from images directly in your browser, without sending data to a server.
Confirmed features: 1. Text‑input – edit the recognized text manually. 2. File‑upload – drag‑and‑drop or select PNG, JPG, or PDF files. 3. Preview – see the extracted text instantly. 4. Copy – send the result to the clipboard with one click. 5. Download – save the output as a .txt file.
How to use it (numbered steps): 1. Click the “Upload” button or drop an image onto the designated area. 2. Wait a few seconds while the OCR engine processes the file locally. 3. Review the preview pane; correct any mistakes using the text‑input box. 4. Press “Copy” to place the text on the clipboard or “Download” to store it as a .txt file. 5. (Optional) Clear the workspace and repeat with another image.
Concrete example: Suppose you have a photo of a street sign in Hanoi that reads “Đường Lê Lợi”. After uploading the picture, the preview shows “Đường Le Loi”. You edit the word “Le” to “Lê” in the text‑input field, then click “Copy” and paste the corrected line into your notes or document.
Useful notes:
- The tool works entirely offline; your images never leave the device.
- High‑contrast, well‑focused images produce the best accuracy.
- Only Vietnamese and English are supported; other languages will not be recognized.
- Files larger than 5 MB may take longer to process, but the engine still runs locally.
- If the OCR output contains errors, try increasing brightness or cropping out unnecessary background before re‑uploading.
Privacy and performance:
- Because processing happens in the browser, no network latency is involved and the OCR speed depends only on your device’s CPU.
- The tool does not store any data; once you close the page, all intermediate results are cleared.
- For best speed, use modern browsers that support WebAssembly, which the OCR engine relies on.
Additional tips:
- Crop the image to include only the text region; this reduces background noise.
- When dealing with printed documents, ensure the text is at least 12 pt; very small fonts may be missed.
- If you need to process many files, use the “Copy” button to paste each result into a single document rather than downloading multiple .txt files.
