How Telugu OCR works
Drop a photo of a Telugu newspaper, a scanned book or certificate, or a screenshot, and the text is recognised and saved as Unicode Telugu for Word, Google Docs, WhatsApp or a translator. Because the output is Unicode, not a legacy font encoding such as the Anu fonts used in older desktop publishing, it displays correctly in any app.
Telugu letters are rounded, and most carry a small tick-like mark on top, the talakattu. Vowels change a consonant through signs called gunintalu, and a consonant cluster is written by placing the second consonant as a small subscript form, a vattu, under the first, as in క్ష or స్త. That puts a lot of meaning into small marks above and below the line. Tesseract's Telugu model reads whole lines with a neural network trained on printed Telugu, which handles these stacked shapes far better than OCR that matched one letter at a time.
Vattulu and the small vowel signs are the first details lost when the print is small or the photo is soft, and letters that differ only by them are then confused. Clean print at a good size reads well; old books, cyclostyled notes and pages with worn type need careful checking.
The Telugu model, about 1.7 MB, downloads from the jsDelivr CDN the first time you press the button and is cached, along with the OCR engine of about 4 MB, so later images start straight away. It is trained on Telugu script, so if the text mixes in English words, tick Also read English words and the English model reads alongside it, a little more slowly. The image itself is read inside this tab and never uploaded. The result is a UTF-8 text file named after the image. For an editable Word document instead, use Image to Word and choose Telugu.
Telugu OCR options explained
| Language | Telugu, already selected. |
|---|---|
| Script | Telugu, written left to right, with subscript consonants (vattulu) below the line. |
| Model size | About 1.7 MB, downloaded once and cached. |
| Output | Plain UTF-8 text, one file per image. |
| Layout | Not kept; the words come out in reading order. |
When to use it
Use Telugu OCR to copy text from a scanned book or newspaper, to type up a photographed government order, notice or application, to search old documents, or to paste Telugu from an image into a translator.
Leave enough resolution for the vattulu: zoom in on the image, and if the subscript letters are a blur of a few pixels, photograph the page again from closer.
About the OCR engine
Text recognition uses Tesseract, the open-source OCR engine first developed at HP, then for many years at Google, and now maintained by its open-source community. Its current generation reads whole lines of text with a neural network (an LSTM) rather than matching letters one at a time, which is what lets it handle joined scripts such as Arabic and Devanagari. Tesseract.js compiles it to WebAssembly so it runs in this tab. Each language has its own trained model, downloaded from the jsDelivr CDN only when that language is chosen and then cached, so reading English never downloads Hindi, and the other way round. The models used here are the integer versions of Tesseract's most accurate models, which keep nearly all of their accuracy at a fraction of the size. Tesseract is built for printed text: it reads books, letters, forms, signs and screenshots well, handwriting poorly, and it keeps the words of a page in reading order but not its layout.
Telugu OCR troubleshooting
Subscript letters are missing
The image is too small or soft for the vattulu. Use a sharper, closer photo.
The result is in English letters
Choose Telugu from the language menu and convert again.

How to use Telugu OCR, step by step
- Press "Choose images" or drag files onto the box.
- Set the options if you need to; the defaults suit most uses.
- Press "Extract text". The work happens on your device.
- Save the result with its download button.
Is it safe to do this online?
With most online tools, "online" means your file is uploaded to a company's server, processed there and kept for a while before it is deleted. Here it is not. The page downloads the tool's code to your browser, and your file is read and processed inside the tab on your own device. It is never sent to TapToConvert or anyone else.
You can check this yourself: once the page and its engine have loaded, turn off Wi-Fi and the tool still works. That also means there is no queue, no daily limit and no file size cap set by a server; the only limit is the memory your browser gives a single tab.
Telugu OCR FAQ

Yes, standard Unicode that works everywhere.
Can it read handwritten Telugu?
Not reliably; it is trained on printed text.
Can I read many pages at once?
Yes. Add all the images; each gets its own text file.
Can I get a Word file?
Yes. Use Image to Word and choose Telugu.
Is it free?
Yes. No sign-up, no watermark and no limit on use. TapToConvert is supported by advertising.
Are my files uploaded?
No. Everything happens inside your browser tab, on your own device.
