Uploading your PDFs, ePubs and documents to Tagsora

Updated

On this page

With Premium you get 5 GB to upload your own files and read them in Tagsora like any other article: with highlights, notes, search, summaries and the reading assistant. They are private: only you see them.

What you can upload

Format Extension Maximum size
PDF .pdf 50 MB
ePub .epub 50 MB
Word .docx 20 MB
LibreOffice (OpenDocument) .odt 20 MB
Markdown .md 2 MB
Plain text .txt 2 MB
Saved web page .html, .mhtml 20 MB

Tagsora recognises the format by what is inside the file, not just by its name. Old Word documents (.doc) cannot be read: open the file in Word or LibreOffice and save it as .docx.

How to upload

In Home, tap + and, below the field for pasting a link, Upload a file. On the web you can also drag the file onto the window. The first time you will see a privacy notice to accept.

The file shows up in your library like any other bookmark, with the Private badge. The Uploaded filter shows only your files, and My files (from your plan, in Settings) lists them with the space you have used.

How they are read

  • PDF and ePub are shown in full, with their original layout: the book’s pages, images and type. They have a table of contents, bookmarks to remember where you stopped and word search inside the document.
  • Word, LibreOffice, plain text, Markdown and saved pages open in reader mode, like an article: with your text settings, a contents list from their headings and their images. You can always download the original.

Everything that works on an article works on them too: highlights and notes, search by meaning across your whole library, automatic tags, summaries and the assistant (which uses the page or chapter you are reading as context). They are read aloud with your device voice; the Premium AI voice does not apply to uploaded files.

Privacy

  • Only you see your files, and your highlights and notes on them.
  • They cannot be published or shared with anyone: not in Spaces, nor in shared collections or compilations. The sharing options appear disabled, with the reason.
  • AI processes them on our server, like the rest of your library.
  • Files with DRM are not accepted.

Your space

You have 5 GB in total. It counts what you upload, even if someone else uploaded the same file. To free up space, delete a file from its detail view or from My files: the file and its highlights are removed from your account.

If you leave Premium

Your files stay in your library and you can still read and highlight them; what you cannot do is upload new ones. They are only deleted if your Premium has expired and you have gone 12 months without using Tagsora, and we email you 30 and 7 days before. Using the app again or going back to Premium prevents it.

Common problems

A scanned PDF. It can be read, but it has no text: it cannot be searched, highlighted or listened to.

A PDF over 20 MB. It is uploaded, read and highlighted in the viewer, but search by meaning, summaries and the assistant only reach PDFs of up to 20 MB.

A very long book. If search and the assistant do not reach the end, the viewer tells you which page they reach. The document is still shown in full.

A password-protected PDF. It cannot be opened in Tagsora: remove the password before uploading it.
