Descubra como partilhar os seus ficheiros em privado entre os seus dispositivos, com os seus amigos e família, ou anonimamente online.

## Gestores de senhas

If you already use [Proton Drive](cloud.md#proton-drive)[^1] or have a [Bitwarden](passwords.md#bitwarden) Premium[^2] subscription, consider using the file sharing capabilities that they each offer, both of which use end-to-end encryption. Otherwise, the standalone options listed here ensure that the files you share are not read by a remote server.

### OnionShare

![Send logo](assets/img/file-sharing-sync/send.svg){ align=right }

**Send** is a fork of Mozilla's discontinued Firefox Send service which allows you to send files to others with a link. Os ficheiros são encriptados no seu dispositivo para não poderem ser lidos pelo servidor e, opcionalmente, também podem ser protegidos por palavra-passe. The maintainer of Send hosts a [public instance](https://send.vis.ee). Pode utilizar outras instâncias públicas ou pode alojar o Send por si.

O Send pode ser utilizado através da sua interface web ou através do [ffsend](https://github.com/timvisee/ffsend) CLI. Se estiver familiarizado com a linha de comandos e enviar ficheiros frequentemente, recomendamos a utilização do cliente CLI para evitar a encriptação baseada em JavaScript. Pode especificar o sinalizador `--host` para utilizar um servidor específico:

```bash
ffsend upload --host https://send.vis.ee/ FILE
```

### OnionShare

<div class="admonition recommendation" markdown>

![OnionShare logo](assets/img/file-sharing-sync/onionshare.svg){ align=right }

**OnionShare** is an open-source tool that lets you securely and [:material-incognito: anonymously](basics/common-threats.md#anonymity-vs-privacy){ .pg-purple } share a file of any size. Funciona iniciando um servidor web acessível como um serviço Tor onion, com um URL indetetável que pode ser partilhado com os destinatários para descarregar ou enviar ficheiros.

## Sincronização de arquivos

### Syncthing (P2P)

<div class="admonition recommendation" markdown>

![Syncthing logo](assets/img/file-sharing-sync/syncthing.svg){ align=right }

**Syncthing** is an open-source peer-to-peer continuous file synchronization utility. It is used to synchronize files between two or more devices over the local network or the internet. Syncthing does not use a centralized server; it uses the [Block Exchange Protocol](https://docs.syncthing.net/specs/bep-v1.html#bep-v1) to transfer data between devices. All data is encrypted using TLS.

### Framadate

**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

#### Requisitos mínimos

- Must not require a third-party remote/cloud server.
- O software deve ser de código aberto.
- Must either have clients for Linux, macOS, and Windows; or have a web interface.

#### Melhor caso

Os nossos melhores critérios representam o que gostaríamos de ver num projeto perfeito desta categoria. As nossas recomendações podem não incluir todas as funcionalidades, mas incluem as que, na nossa opinião, têm um impacto mais elevado.

- Should have mobile clients for iOS and Android which at least support document previews.
- Should support photo backups from iOS and Android, and optionally support file/folder sync on Android.

[^1]: Proton Drive allows you to [share files or folders](https://proton.me/support/drive-shareable-link) by generating a shareable public link or sending a unique link to a designated email address. Public links can be protected with a password, set to expire, and completely revoked, while links shared via email can have custom permissions and be similarly revoked. Per Proton Drive's [privacy policy](https://proton.me/drive/privacy-policy), file contents, file and folder names, and thumbnail previews are end-to-end encrypted.
[^2]: With a [premium](https://bitwarden.com/help/about-bitwarden-plans/#compare-personal-plans) subscription, [Bitwarden Send](https://bitwarden.com/products/send) allows you to share files and text securely with [end-to-end encryption](https://bitwarden.com/help/send-encryption). A [password](https://bitwarden.com/help/send-privacy/#send-passwords) can be required along with the Send link. Bitwarden Send also features [automatic deletion](https://bitwarden.com/help/send-lifespan).
