> European Portuguese; also reads English.

- What it does: a photo or PDF goes in, clean text comes out. PDFs that are
  already digital return their own text layer, untouched (more faithful).
- Privacy: files are processed in memory and never stored; no cookies, no
  trackers, and no accounts of any kind — there is nothing to sign up for.
- Measured accuracy: 98 out of 100 words read correctly on a phone photo of
  an official Portuguese certificate (87 out of 100 without processing).
- Formats: JPG, PNG, WebP, PDF; up to 20 MB per upload.
- Pricing: free to use, with no account; an everyday plan for people who read
  paper daily, and company integrations quoted per project — both arranged by
  a payment link, never by a checkout invented on the page.
- Operator: Decalca — an independent product.
- Languages: English is the main language (https://decalca.com/en); European Portuguese at
  https://decalca.com/pt. The root URL redirects by the visitor's Accept-Language and falls
  back to English.
- Common searches it answers: image to text, jpg to text, png to text,
  pdf to text, photo to text, Portuguese OCR online, extract text from a
  photo, scan a document with a phone.
- For developers: POST /api/digitalizar with JSON {"nome", "dados": base64,
  "lingua": "pt"|"en"}; the response carries the text, the cleaned image and
  any notices.
