Frequently Asked Questions
Blurring text in an image hides written information so it cannot be easily read in the final version. It is commonly used to protect phone numbers, email addresses, account details, personal information, captions, signs, forms, receipts, screenshots, and other sensitive text before sharing or publishing an image.
Yes. The Detect and Blur Text button scans the image for visible words and blurs every detected text region in one pass. After automatic detection finishes, you can still draw manual blur boxes over anything that was missed or any extra area you want to hide.
The downloaded image contains the blurred version of the text, so the original wording is not easily readable in that exported file. Your original source image is not modified, which means you can always keep the untouched version separately if needed.
No. The OCR model runs locally in your browser, so both the source image and the detected text remain on your device during processing. The tool does not send the image to a remote server for text recognition.
No. All processing happens locally in your browser using HTML Canvas and the OCR model loaded into the page. Your images never leave your device while text is detected, blurred, and downloaded.
