Screenshot to Text

Copies text out of a screenshot — an error message, a chat, a table in an app — by enlarging the image first, which is what makes small interface text readable.

Runs in your browser — nothing is uploaded

Your screenshot

A screen grab of a page, an error message, a chat.

The model for each language downloads once and is then cached.

Your file never leaves this device. The whole operation runs in your browser — nothing is uploaded, queued on a server, or deleted later, because nothing was ever sent.

Choose an image and press read

Screenshots are enlarged before reading

Recognition accuracy depends on how many pixels each character occupies, and interface text in a screen grab is often eleven or twelve pixels tall — smaller than the model expects. Small images are doubled first, which is the difference between usable text and nonsense.

Why use it

Built to be genuinely useful

Small screenshots are enlarged first

Interface text is often twelve pixels tall, below what recognition models expect. Doubling it is the difference between usable output and nonsense.

Made for error messages

The fastest way to get a copyable error out of a screenshot somebody sent you.

Runs in your browser

Screenshots often contain private information. This one never uploads them.

Free, no sign-up

No account and no limits.

How it works

Three steps

  1. 1

    Choose your screenshot.

  2. 2

    Pick the language.

  3. 3

    Press read, then copy the text.

Why a screenshot is harder than a photograph

It seems like it should be easier — a screenshot is perfectly sharp, perfectly lit and perfectly straight, with none of the problems that make photographing a page difficult. But recognition accuracy depends on how many pixels each character occupies, and interface text is small by design.

Body text in an app is typically 12 to 14 CSS pixels, which on a standard-density screen grab is 12 to 14 actual pixels tall — and the lowercase letters within that are perhaps eight. Recognition models are trained on scanned documents where characters are two or three times that, so a screenshot is genuinely out-of-distribution input.

Enlarging it first, with smooth interpolation, brings the characters back into the range the model expects. It adds no information, and it does not need to: the shapes are already unambiguous, they were simply too small to measure. That single step is why this is a separate tool rather than the photo one with a different label.

Getting a better screenshot

Capture at the highest resolution you can. On a laptop, zoom the page in before taking the shot — text at 150% or 200% is dramatically easier to recognise than the same text at 100%, and costs nothing.

Crop tightly to the text you want. Buttons, icons and window furniture all produce spurious characters, and cropping them out is faster than deleting the results afterwards.

Avoid photographing a screen with a phone if you can screenshot instead. A photo of a monitor brings back every problem of the photographic case, plus moiré patterns from the screen's own pixel grid.
