Know what Ratdolt can open

Understand public-network, access, size, media and site-owner policy boundaries before troubleshooting.

01

Public URL boundary

Ratdolt accepts ordinary public HTTP(S) sources. It refuses embedded credentials, private or local network targets, login-dependent material and other unsafe destinations. Video, audio, iframes and active scripts are not preserved inside reading editions.

  1. Confirm that the URL opens publicly without your signed-in browser state.
  2. Remove tracking fragments or embedded credentials.
  3. Use a local PDF in Composer when the source is a document on your device.
02

Owner policy and limits

An exact host may publish a same-origin well-known Ratdolt manifest to identify content roots, exclusions and image permission. It can narrow acquisition but never relax safety, access or product limits.
