A PNG image — reads the text with in-browser OCR (first run downloads the OCR engine)
Turn a PNG into copyable text. PNG is the format screenshots and exported UI graphics usually use, and it's often the sharpest source you can hand an OCR engine — crisp edges and no JPEG compression noise mean the letters are easy to read.
Why PNG screenshots read so well
PNG is lossless, so it doesn't add the blocky artefacts that JPEG smears around text edges. A screenshot captured as PNG keeps every letter crisp and the background even — exactly the conditions Tesseract wants. That's why extracting text from a PNG screenshot is usually more accurate than from a photo of the same text.
The recognition runs locally in your browser, so a screenshot of an email, an error message, or a slide is decoded and read on your own machine and never uploaded.
Troubleshooting
- The text comes out jumbled or in the wrong order.
- Multi-column layouts, tables, and text wrapped around images confuse the reading order. Crop to a single block of text before running it, or expect to reorder columns yourself.
- Small UI text isn't recognised.
- If the letters are only a few pixels tall, there isn't enough detail. Recapture the screenshot at a larger zoom or a higher display scale, then try again.
- Light text on a transparent background reads poorly.
- OCR reads the visible pixels; very low contrast against whatever shows through causes misreads. Flatten the PNG onto a solid, contrasting background first.
Frequently asked questions
- Is the PNG uploaded anywhere?
- No. The image is read in your browser with a WebAssembly OCR engine and never sent to a server, so private screenshots stay private.
- What languages are supported?
- Latin-script text (English and similar) by default. Non-Latin scripts require separate trained data that isn't loaded, so they won't be recognised correctly.
