Konvizi’s “Image to Text (OCR)” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your JPG, PNG or WebP files into the box above or click “Choose files”. You can add several.
It helps recognise accents and words. Then click “Read text”.
The recognised text appears under each image: copy it in one click, or download it as a .txt file.
OCR (optical character recognition) finds the letters in an image and turns them into real text that you can copy, search or edit. Konvizi uses Tesseract, the leading open-source engine, right inside your browser. It reads printed text very well: documents, screenshots, posters, receipts. Handwriting, on the other hand, is rarely recognised well.
These are the three most common image formats: JPG for photos, PNG for screenshots and logos (it supports transparency), WebP for websites. Each image keeps its format: a PNG stays a PNG, transparency included.
Text recognition usually means sending your scans to an online service. Konvizi runs Tesseract, the leading open-source OCR engine, right in your browser: your scanned documents stay with you. The engine and language model are downloaded from konvizi.com the first time, then kept by your browser.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up and no limit on the number of images.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
English, French, Spanish, Portuguese and Hindi. The first time, your browser downloads the recognition engine and the language model (a few MB) from Konvizi, then keeps them for next time.
Use a sharp, well-lit, straight image where the text is large enough. A blurry, tilted or low-resolution photo leads to mistakes. For a multi-page document, scan it to PDF and use “OCR PDF”.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
