Understanding Syncing with Mylio

Keeping all of your memories on all of your devices is easy with Mylio. Syncing allows each of your devices, whether it be computers, phones, tablets or external hard drives to always have the same information. Syncing also ensures that new photos added to one device are available on other devices and that edits, metadata, and organization changes made on one device are available on all of your devices.

How Syncing Works

Mylio syncs over a peer-to-peer connection to ensure that photos and videos are shared between your devices quickly and safely. Peer-to-peer means that your devices do not utilize the internet or the cloud to transfer photos. Instead, Mylio uses a direct wireless connection between your devices to sync information. Mylio gains this direct connection by looking at your devices on a network. This network can be a home wireless network, a wired/wireless hybrid network, or even an open Wi-Fi network (restrictions apply). Even though Mylio utilizes a network, it does not require the internet – simply that your devices be connected to the same network.

Mylio must meet three criteria in order to sync your devices:

  1. All devices must be logged into the same Mylio account.
  2. All devices must be connected to the same network.
  3. All devices must be running Mylio (Mylio must be in the foreground on mobile devices).

When these three criteria are met Mylio will transfer your photos, videos, edits, metadata, and organization between all of your devices quickly and safely.

Photo Quality Basics

In its default state, Mylio is designed for you to only need to answer one question:

Do I want to store all of my original photos on this device, or do I want Mylio to automatically optimize my images for me to save space?

Devices that hold all Originals are designed to keep your information safe by keeping a copy of all of your files. And the more devices you have that hold all Originals, the safer your photos are. Devices that hold all Originals can be any one that has enough storage to hold your entire photo library, but popular Vaults are cloud storage providers, external hard drives, NAS devices, and desktop computers.

Mylio has three different photo quality sizes that can be stored on your devices:

  • Thumbnails – A small version of your photos (20kb to 30kb) that is great for referencing your full library. Ideal for mobile devices. Does not allow editing.
  • Previews – Medium quality (approximately 1mb) that gives an accurate representation of your photos at a fraction of the space. Perfect for laptops. Fully editable.
  • Originals – Your full quality file (original file size). RAW compatible. Fully editable.

If you have told Mylio to automatically optimize the storage of your device, we’ll choose what photo quality we think you’ll want to see based on specific criteria.

You can change a device between a Vault and Auto-Optimized quality by:

  1. Open Mylio and select the Dashboard.
  2. Select the device that you wish to change between a Vault and Auto-Optimized quality to open the Device Settings.
  3. Select Device Quality.
  4. When viewing just the default Simple Device Settings, you can toggle between Originals and Auto Optimized as your desired quality. You can also create a Custom Device Sync Policy by toggling on Advanced Settings. 

Advanced Quality Settings

If you’re looking for a bit more control over how your images sync, then Mylio’s Advanced syncing options are for you.

When toggling on Advanced syncing options, Mylio allows you to change your device’s Sync Policy on a more granular level. Your device’s Sync Policy is what quality of photo your device will sync images in. Any new photo added to Mylio on another device will sync to this device in this quality.

To turn on Mylio’s Advanced sync options, simply:

  1. Open Mylio and select Dashboard.
  2. Select the device you want to change and select Device Quality.
  3. In the Device Quality Settings, toggle on the Advanced option under Device Quality to show Mylio’s advanced Sync Policies.

Mylio has three different Sync Policies:

  • Thumbnails – A small version of your photos (20kb to 30kb) that is great for referencing your full library. Ideal for mobile devices. Does not allow editing.
  • Auto-Optimized – Mylio will manage your library based on the available storage on your device.
  • Originals – All three file types are stored. Great for desktops.


To learn more about setting Custom Sync Policies, please see this article. Any Custom Sync Policies to the device or folders will override the sync policy set at the top of this window. You can reset any folders or custom policies overriding the Device Sync Policy by selecting the “Reset Device Quality” button at the bottom.
