Can I just paste instead of choosing a file?
Yes. Copy the screenshot and press Ctrl+V (Cmd+V on a Mac) anywhere on this page — the image goes straight in. That is usually faster than saving it first.
Is my image uploaded?
No. Tesseract is compiled to WebAssembly and runs in a worker inside this browser tab, on your own processor. Watch the Network tab while it works — your file never appears in a request. That is the reason to use this rather than an online OCR service for anything containing personal or financial information.
Why is the first run slow?
It downloads the OCR engine and the English training data once, about 15 MB together. Your browser caches both, so every later run starts straight away.
How do I get better accuracy?
Improve the image before you improve the settings. Photograph the page square-on rather than at an angle, fill the frame, get even light with no shadow across the text, and avoid flash glare. A 300 DPI scan beats any phone photo. Small screenshots are upscaled automatically here, which helps a little.
Can it read handwriting?
Barely, and you should not rely on it. Tesseract is trained on printed text. Neat block capitals sometimes come through; ordinary cursive does not. If you need handwriting recognition, this is the wrong tool and honesty is more useful than a bad result.
Which languages work?
English only on this site, because each additional language pack is another 10–15 MB visitors would have to download. English OCR handles most Latin-script text passably even when the language is not English, but accented characters will suffer.
Is the Screenshot to Text free?
It is free, with no account, no trial and no daily cap. Every ocr tool on inputtesthub.com works the same way: open the page and use it.
Is what I paste into the Screenshot to Text stored?
No. The Screenshot to Text runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
When would I actually need the Screenshot to Text?
The most common reasons people reach for it: copying an error message out of a dialog that will not let you select it. Getting text out of a video still or a shared screenshot. Retrieving text from an image-only PDF page. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything to watch out for?
The first run downloads about 15 MB of engine and English language data, once. After that it starts immediately. Accuracy depends almost entirely on the source image: straight, well lit, high contrast and reasonably large. A photo taken at an angle or a small low-contrast screenshot will disappoint no matter what software reads it.
Will a big file be rejected?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
