Нови та дрехи на царь-ть.
Прѣди много години живѣялъ на тоя свѣтъ единъ царь, кой-
то до толкова обичалъ да бжде облѣченъ въ ново, штото всички-
тѣ си пари разносвалъ за нови дрѣхи. Той никакъ не се грижилъ
за войска-та си, не обръшталъ никакво внимание на театръ-тъ, а на
расходка излѣзвалъ само и само да покаже нови-тѣ си дрѣхи. Слѣдъ
всякой часъ прѣзъ день-тъ той обличалъ новъ сюртукъ и както за
другъ единъ царь, всякога казовали:„той е въ държавний съвѣтъ,"
така за тогова казовали всякога:„царь-тъ се облича!"
Въ столица-та на царь-тъ било много весело: всякой Божий
день идвали отъ разни царства всякакви иностранци. Еднжжь дошли
двама лъжци: Тии казовали, че са тъкачи и могать да тъкжть най-
скжни и драгоцѣнни платове, каквито никой не може да си прѣд-
стави; нъ освѣнь хубави-тѣ бои платове-тѣ имъ обладавали оште
едно твърдѣ чудно нѣшто, а именно: тѣхъ не може да ги види
тоя, който е недостоенъ да занимава служба-та, на която се намѣр-
на или пакъ е тжпъ и глупавъ. Чудесни дрѣхи! помислилъ
царь-тъ. Штомъ имам такива дрѣхи, азъ шта знак, кои отъ мои
тв чиновници ск недостойни за служба та си, азъ штх могж да от-
личавать умни-тѣ отъ глупави-тѣ! Да, трѣбова безъ друго да ми
истькать колкото е възможно по-скоро отъ тоя плать.
Царь-тъ повикалъ лъжци-тѣ далъ имъ много пари и имъ за-
ржчалъ да му истъкять чудний плать.
Лъжцитѣ турнали станове и се правили като га-че тъкать,
нъ на станове-тѣ нѣмало ништо! Тии непрѣстайно искали тънка
коприна и злато за плать-тъ; всичко това отивало въ джебове-ть
имъ, а тии все стояли при праздни-тѣ станове отъ сутринь до ве-
черь и се прѣстрували, че тъкать.
- Иска ми се да знак, много ли ск истъкали кои-тѣ тъка-
чи! помислилъ царь-тъ. Нъ штомъ си припомнилъ, че глупави тѣ
людю не могать да видять плать-тъ, царь-тъ се исчървилъ и сръд-
це-то му захванало силно да тупа. Разбира се, той се надѣвалъ,
че съ него нѣма да се случи това чудо, нъ все пакъ искал да
проводи другиго.
Всички-ть жителе на столица-та знаяли за чудно-то свойство
на платъ-тъ и съ нетърпение чакали да узнають до колко са глу
пави съсѣдить имъ.
Шта проводж при тъкачи-гѣ моя старъ и почтенъ министръ!
помислилъ си царь-тъ. Той ште види добрѣ платъ-тъ, заштото авъ
го знать, че е уменъ и испълнява добрѣ длъжности-тѣ си.Original text order preserved

What is Bulgarian OCR & Developer API?
Developer API docs →Bulgarian OCR is the automated process of converting scanned multi-page PDFs up to 1GB and documents into editable, searchable Bulgarian text while preserving accents, complex ligatures, and native character shapes. FastOCR reads printed text in this script and generates full-text searchable PDFs with selectable text overlays. For engineering teams building RAG pipelines, vector search databases, or automated document ingestion, FastOCR also provides a Bulgarian OCR REST API at api.fastocr.org with 20 free pages a month for every signed-in account. The API accepts PDF files up to 1 GiB, and PNG, JPG, JPEG, GIF, WebP and BMP images up to 20 MiB. An image counts as one page.

Why Bulgarian OCR Is Challenging
- Recognizing the Bulgarian letter ъ (yer golyam) — a unique Cyrillic vowel that looks like ь with a different placement
- Distinguishing Bulgarian Cyrillic from similar-looking Latin capitals: В/B, Н/H, Р/P, С/C, У/Y
- Handling the я (ya) and ю (yu) iotated vowels which have distinctive shapes unique to Cyrillic
- Processing documents mixing Bulgarian with Russian, English, or Turkish loanwords
- Correctly interpreting Bulgarian typographic conventions where italics and upright forms of Cyrillic differ significantly
How to Extract Bulgarian Text from a PDF & Images
- Go to fastocr.org
- Upload your Bulgarian image or PDF. Language is detected automatically.
- Wait for processing — images take seconds, PDFs show a progress bar.
- Download results: searchable PDF, raw text file, or copy text directly.
Tips for Better Bulgarian OCR Accuracy
- Scan at 300 DPI to preserve the fine Cyrillic forms — Bulgarian italics (курсив) look very different from upright
- Verify ъ (yer golyam) is correctly recognized — confusing it with ь or b changes word meaning
- Check that Bulgarian Cyrillic is not partially romanized in the output (e.g., В→B, Н→H)
- For bilingual Bulgarian-English documents, ensure the script boundary is correctly detected
- Use high-contrast scans to distinguish similar Cyrillic letters like и/й/ы and ш/щ
Common Use Cases for Bulgarian OCR
- Digitizing Bulgarian legal documents, contracts, and court rulings
- Extracting text from Bulgarian government forms and official certificates
- Converting scanned Bulgarian academic papers and university publications
- Processing Bulgarian business invoices and EU trade documentation
- Archiving historical Bulgarian documents and Ottoman-era records

Frequently Asked Questions
Does Bulgarian OCR handle the letter ъ correctly?
Yes. FastOCR recognizes ъ (yer golyam), the characteristic Bulgarian vowel. While ъ in Russian is a "hard sign" (silent), in Bulgarian it is a distinct vowel sound — our model handles this correctly.
How does Bulgarian OCR differ from Russian OCR?
Bulgarian uses a 30-letter Cyrillic alphabet without the Russian letters ы, э, ё which are absent from Bulgarian. Bulgarian also uses ъ as a vowel (not a hard sign). FastOCR auto-detects Bulgarian vs Russian Cyrillic.
Can it handle Bulgarian documents mixed with English text?
Yes. FastOCR handles bilingual Bulgarian-English documents in a single pass, correctly identifying Cyrillic and Latin script boundaries.
Is Bulgarian OCR free?
Image OCR is free with no registration. PDF processing requires a free account — see fastocr.org/pricing for plan details.
