Image Text OCR failed or looks wrong? Troubleshooting guide
Troubleshoot extensions, file structure, dependencies, encoding, memory, and output error in Image Text OCR while preserving the source.
Preserve the source first
Do not rename and overwrite the original, and do not treat a browser preview as the only acceptance record. Use a small copy and record size, producer, version, browser, and exact error.
The easy-to-miss fact for this format
For a clear shipping-label photo, crop the background and select the language. Verify tracking IDs, amounts, and names character by character; OCR is not document validation.
Recommended troubleshooting order
- Test the page example or a smaller known-good file to confirm the tool runs.
- Check extension, signature, companion files, remote URL, and CORS; exclude a downloaded HTML error page.
- Supply the input again according to the workflow:
- Choose one clear, correctly oriented image.
- Select the main language and optionally crop the target region.
- Start recognition and wait for browser OCR.
- Compare every line with the image before copying or downloading.
- Close memory-heavy tabs and retry in current Chrome or Edge.
- If it still fails, re-export from the producing application and validate in the receiving system.
Common questions and answers
Why is Chinese output garbled?
Select Chinese and use a clear source without heavy compression or skew.
Can it read handwriting?
It may try, but the first version targets printed text and does not promise handwriting accuracy.
Is the image uploaded?
Processing runs in this browser tab; the file is not uploaded to FreeTool to perform the task.
Limits that must not be bypassed
- Handwriting, curvature, blur, and complex tables reduce accuracy
- Original layout, tables, and reading order are not guaranteed
- Critical IDs, amounts, and names require human review
Privacy handling
Local input is not uploaded to FreeTool for processing; remote IIIF/DZI URLs are requested by the browser from their source. Troubleshooting images, OCR text, model summaries, and converted files may contain sensitive or copyrighted content. De-identify and confirm rights before sharing.
