Text you can see but can’t select
Error messages captured as screenshots, receipts photographed for an expense claim, a paragraph from a scanned letter — the text is right there on screen, but the clipboard can’t touch it. Retyping is slow and error-prone, and pasting a sensitive document into a random upload-based OCR site trades one problem for a worse one. Optical character recognition solves it properly: software reads the pixels, identifies the characters, and hands you editable text. The tool described here runs Tesseract, the open-source OCR engine, compiled to WebAssembly so it can do that work inside an ordinary browser tab.
Step by step
- Open the Image to Text tool on SafeFileConvert. On your first visit the page fetches the recognition engine — about 15 MB — and your browser caches it, so every later session starts without the wait.
- Set the recognition language before scanning if your document isn’t in English, which is the default. Matching the language to the document gives noticeably better accuracy.
- Drop your screenshot, scan, or photo onto the dropzone and let the engine work through it; a background thread scans the image for characters and assembles the result.
- Review the recognized text, then copy it straight to your clipboard or save it as a .txt file — whichever fits where the text is headed next.
Getting an accurate read
OCR quality tracks input quality. Clean screenshots and upright, well-lit scans of printed documents usually come out close to perfect; phone photos work too, but accuracy improves noticeably with even lighting, a straight-on angle, and a page that lies flat. Cropping out background clutter before scanning helps as well. Two limits are worth knowing up front: handwriting isn’t supported, because the engine is trained on printed and typed characters, and very small or low-contrast text is often misread. When a result looks rough, a better capture usually fixes more than any setting will.
Why on-device OCR is the right default
Think about what actually goes through OCR: passports, ID cards, receipts, contracts, medical letters. Uploading those to a conversion server means trusting someone else’s retention policy. Here, the one-time engine download is the only network activity involved — the image itself is read straight from disk into memory and processed on your own hardware, so there is nothing for a server to log, store, or leak. Once the engine is cached you could even go offline and the tool would still work. There are no accounts, no daily task caps, and no watermarks either — restrictions that are common on upload-based OCR sites.
