Cyrillic OCR

100% in your browser: nothing is uploaded

Loading…

Read Cyrillic script from an image: Bulgarian, Macedonian, Serbian, Kazakh, Mongolian and around 30 more, with English on the same page read by the same model. If your document is Russian, Ukrainian or Belarusian, use the East Slavic pack instead — it is trained on those three specifically and is more accurate on them than this general one.

How it works

  1. Drop an image or PDF. Text detection runs immediately.
  2. Pick your language pack (downloaded once, 8–17 MB) and press Read text.
  3. Copy the lines, or download .txt / .json. PDFs are read cover to cover.

Questions

Cyrillic or East Slavic — which do I want?
East Slavic for Russian, Ukrainian and Belarusian; this one for everything else written in Cyrillic. Both are about 8 MB, both also read English, and you can switch packs in the picker without reloading the page.
Does my file get uploaded?
No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
Which languages are supported?
106 languages across Latin, Cyrillic, Arabic, Devanagari, CJK, Greek, Thai, Tamil and Telugu scripts. Bengali is the one major gap, since no v5 model exists for it yet, and the picker says so rather than guessing.
How accurate is it?
On clean document text, the measured character error rate is under 2%, and every line carries a confidence score so you can see which ones to check. Handwriting and low-resolution photos will read worse.
Does it read scanned PDFs?
Yes. Digital PDFs are read from their own text layer, with exact characters at exact positions. Scanned pages go through detection and recognition, and mixed documents use both.
