Does image-to-text work in every browser?

No. The browser TextDetector API is experimental and not exposed by every browser. The tool shows an unsupported message when the API is unavailable.

Why is detected text incomplete?

Browser-native detection is best for clear printed text. Low contrast, handwriting, skew, blur, or small text may be missed.

How do I check that the image is not uploaded?

Open DevTools, switch to Network, filter Fetch/XHR, then choose an image. The tool should not send the file in any request.

How to Extract Text from an Image in the Browser

By Rui Barreira · Last updated: 13 June 2026

Image-to-text tools usually work by uploading a photo to an OCR service. brevio Image to Text takes a stricter approach: it uses browser-native text detection when available and does not call an OCR API.

TextDetector vs OCR APIs

The browser TextDetector API can detect visible text regions in images, but support is still experimental. Full OCR APIs usually support more languages, handwriting, skew correction, and scanned documents, but they require sending the image to a server.

What Works Best

High-contrast screenshots
Printed text with clear edges
Images without blur, glare, or strong perspective distortion

What May Fail

Handwriting, small receipts, low-light photos, rotated text, and dense document scans may be missed. When the browser does not expose TextDetector, the tool reports that limitation instead of silently uploading to a fallback service.

Verify No Upload

Open DevTools, switch to the Network tab, filter for Fetch/XHR, and choose an image. The preview uses a temporary object URL in the browser; no file should be posted to a server.
