# FAQ

> Limits, browsers, phones, and where the edges are.

<AccordionGroup>
  <Accordion title="Do I need an account or an app?">
    Neither. Sidedrop is a website — open it on both devices, pair them, and drop files. There's
    nothing to install and no sign-up, so there's also nothing about you to store.
  </Accordion>

  <Accordion title="Is there a file size limit?">
    There's no artificial cap. Received files stream to on-disk storage in your browser rather than
    memory, so large files (multi-gigabyte) work — bounded in practice only by free disk space. The
    exception is receiving a very large file on a phone, which some mobile browsers limit.
  </Accordion>

  <Accordion title="Does it only work on the same Wi-Fi?">
    No. Sidedrop works across different networks — your phone on cellular to your laptop on Wi-Fi,
    or to someone across the world. It uses a direct peer-to-peer connection, with a relay fallback
    for networks that won't allow a direct one.
  </Accordion>

  <Accordion title="Can I send to another person, not just my own devices?">
    Yes. Share the room link through any messenger; when they open it, the two of you are paired and
    you can send. The transfer is still direct and encrypted between your two browsers.
  </Accordion>

  <Accordion title="What happens if my connection drops mid-transfer?">
    It pauses and picks up where it left off once the path is re-established — only the missing
    pieces are resent, not the whole file. This holds while both tabs stay open. Fully closing or
    reloading a tab ends that session; Sidedrop isn't cloud storage, so there's no "resume later."
  </Accordion>

  <Accordion title="Which browsers work best?">
    Chrome and Edge on desktop have the smoothest experience, including a native "save as" dialog and
    folder saving. Firefox and Safari work too, saving via ordinary downloads (a zip for folders and
    batches). Sending works everywhere, including phones.
  </Accordion>

  <Accordion title="What does it cost?">
    Nothing. Sidedrop is free and open source, with no paid tier and no ads. It's a showcase project
    and a small thank-you, not a business — an optional GitHub Sponsors link is the only ask.
