Convert
Browse all convert toolsconverting documents into accessible/alternate formats with RoboBraille: Braille transcription (contracted/uncontracted) in its documented 18 language codes and emboss-ready digital Braille formats; MP3 and DAISY talking books, including spoken math; EPUB, Mobi Pocket/Kindle and EPUB3 with media overlays; and accessibility conversion of image files, image-only or other PDFs and Microsoft Office documents into tagged PDF, DOC/DOCX, Word XML, XLS/XLSX, CSV, TXT, RTF, HTML or PowerPoint-to-RTF/web-project outputs.
The scope records conversion/OCR-based alternate-format production through the hosted email/web service, and explicitly excludes general PDF editing, extraction APIs, redaction, signing, accessibility certification, guaranteed OCR/Braille/audio accuracy and arbitrary format conversion
Where your files are processed
Files leave your device
We observed a file upload to robobraille.org.
A hosted email/web-form service: source documents are received on the RoboBraille reception server, processed automatically by agents, and returned by email; the source is subsequently deleted. Target documents stay on delivery servers for up to seven days and are then deleted.
The service is hosted in Sensus's own data centre in Denmark. Files leave the device; this is not local processing.
What it does
RoboBraille is a hosted email/web-form conversion service for accessible formats. It offers Braille transcription (contracted and uncontracted) in 18 languages, MP3/DAISY talking books with voices in many languages, EPUB/Mobi Pocket/Kindle e-books including EPUB3 with media overlays, and accessibility conversion of images/PDFs/Office documents into tagged PDF, DOC/DOCX, Word XML, XLS/XLSX, CSV, TXT, RTF and HTML.
It is free for individual, non-commercial users not affiliated with an institution obligated to provide support, needs no registration, and is hosted in Sensus's own data centre in Denmark. Institutional use requires a subscription/service agreement.
Conversion is automated; source documents are deleted after processing and target documents are kept for up to seven days. It is a conversion service, not an editor, validator or legal-accessibility certification.
Best for
Individual users who need their own material in Braille, audio or a reflowable format and have nobody to ask, and universities and libraries that want a self-service conversion service for their users without building one.
Worth knowing
It is a hosted service: source documents are uploaded to the RoboBraille reception server, processed automatically and returned, then the source is deleted; target documents remain on delivery servers for up to seven days. It is free only for individual, non-commercial users not affiliated with an institution obligated to provide support; institutional and organised-instruction use requires a paid service agreement with Sensus, and no public price is published.
The output is produced by conversion and OCR, so it is aimed at getting usable text/alternate formats out of an inaccessible document, not at repairing tag structure in an already-tagged PDF. Braille/audio quality is bounded by the source and OCR.
No API is documented; submission is by email/web form. It is not a general PDF editor, redaction, signing or accessibility-certification service, and no legal/compliance guarantee is made.
It is RoboBraille, not SensusAccess (a related institutional service) or a generic file converter.

What the redaction verdict rests on
From the vendor's own documentation, read 22 September 2026. Not tested by us.
“RoboBraille is an e-mail and web-based service capable of automatically transforming documents into a variety of alternate formats for the visually and reading impaired.”
What that does not establish
Recorded as `none` on absence: the service converts documents into other formats - Braille, audio, e-books, tagged PDF, Office formats, text - and nothing in its documentation describes removing content from a document. It transforms rather than edits.
What it does not establish: what the converted output contains. A tagged PDF built from an untagged source is a new document, and neither the service nor this index makes any claim about hidden data carried across in the conversion; a reader treating it as a redaction step would be using it for something it does not describe.
What the vendor says
Claims are labelled rather than repeated as fact. Where we have checked something ourselves, it says so and shows when. Checked means we read the vendor's own page and it says what we recorded - not that we tested the behaviour, unless the note says we did.

How we checked
Read as rendered text in headless Chrome on 2026-10-01 and saved to the evidence archive, so the read can be repeated against the same file. Comparison ignores case, punctuation and hyphenation, which is why "open-source" on the record matches "open source" on the page.
