Dom Casmurro, 1899
Real scan. Unedited OCR.
DOM CASMURRO OT
e quasi todas creem na mocidade. Duas ou tres
fariam crer nella aos outros, mas a lingua que
falam obriga muita vez a consultar os diccionarios,
e tal frequencia é cançativa.
Entretanto, vida differente não quer dizer vida
peor; é outra cousa. A certos respeitos, aquella
vida antiga apparece-me despida de muitos en-
cantos que lhe achei; mas é tambem exacto que
perdeu muito espinho que a fez molesta, e, de me-
moria, conservo alguma recordação doce e feiti-
ceira. Em verdade, pouco appareço e menos falo.
Distracções raras. O mais do tempo é gasto em
hortar, jardinar e ler; como bem e não durmo mal.
Ora, como tudo cança, esta monotonia acabou
por exhaurir-me tambem. Quiz variar, e lembrou-
me escrever um livro. Jurisprudencia, philosophia
e politica acudiram-me, mas não me acudiram as
forças necessarias. Depois, pensei em fazer uma
Historia dos Suburbios, menos secca que as memo-
rias do padre Luiz Gonçalves dos Santos, relativas
á cidade; era obra modesta, mas exigia documentos
e dalas, como preliminares, tudo arido e longo.
Foi então que os bustos pintados nas paredes en-
traram a falar-me e a dizer-me que, uma vez que
elles não alcançavam reconstituir-me os tempos
idos, pegasse da penna e contasse alguns. Talvez a
narração me désse a illusão, e as sombras viessem
perpassar ligeiras, como ao poeta, não o do trem,
mas o do Fausto: Ahi vindes outra vez, inquietas
sombras...?

What is Portuguese OCR & Developer API?
Developer API docs →Portuguese OCR is the automated process of converting scanned multi-page PDFs up to 1GB and documents into editable, searchable Portuguese 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 Portuguese OCR REST API at api.fastocr.org with 50 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 Portuguese OCR Is Challenging
- Preserving nasal tildes on ã and õ which are phonemically distinct in Portuguese
- Recognizing the cedilla (ç) and not confusing it with a plain c in low-resolution scans
- Handling the full range of Portuguese diacritics: á, â, à, ã, é, ê, í, ó, ô, õ, ú, ç
- Processing documents with differences between Brazilian and European Portuguese orthography
- Correctly interpreting trema (ü) in pre-2009 Brazilian Portuguese texts

Tips for Better Portuguese OCR Accuracy
- Verify nasal tildes (ã, õ) after OCR — they are essential for correct Portuguese pronunciation and meaning
- Check cedilla (ç) is preserved and not converted to plain c, especially in words like ação, coração
- Be aware of Brazilian vs European Portuguese spelling differences when proofreading OCR output
- Scan at 300 DPI to preserve circumflex (â, ê, ô) and acute accents on small text
- For pre-2009 Brazilian texts, watch for trema (ü) which was removed in the orthographic reform
Common Use Cases for Portuguese OCR
- Digitizing Brazilian legal documents, contracts, and court filings
- Extracting text from Portuguese government forms and official certificates
- Converting scanned Portuguese academic papers and university publications
