Document & eBook Conversion — Frequently Asked Questions
How ReadLoudly's converters work, what they preserve, and what they cost.
Conversions cover the major document, ebook, comic and image formats — PDF, EPUB, MOBI, AZW, AZW3, FB2, DOCX, ODT, RTF, TXT, HTML, CBZ, CBR and common image types. Every available pair has its own page listed above.
Yes. Basic conversions are free with no signup and no watermark on the output. Signing in raises the file size limit and gives your jobs priority in the processing queue.
Images, fonts, headings and document structure are preserved wherever the target format can represent them. Converting a reflowable ebook into a fixed-layout PDF necessarily makes pagination decisions for you, which is the one place output commonly differs from expectation.
Calibre for document and ebook conversion and ImageMagick for image work — the same industry-standard tooling you would install locally, run on our servers so you do not have to.
Most files finish in under 30 seconds. Large, image-heavy or very long documents can take a minute or two; the page updates by itself, so there is no need to refresh.
Yes. Files are encrypted in transit, processed, and then deleted automatically along with their output. ReadLoudly does not read, retain or share converted content.
No. DRM-locked files from Amazon, Kobo or Adobe cannot be converted by ReadLoudly or by any other third-party tool. DRM-free files convert normally.
