A `Preset` is a group of settings specifically tailored for the software or device you want your videos to play on. Selecting a `Preset` can go a long way toward ensuring your video works where you want it to.
HandBrake includes a number of official `Presets` that select specific settings to ensure compatibility for specific devices and for general use. When selecting one of these `Presets`, higher resolution video will be downscaled to a maximum resolution, and higher frame rates will be peak limited to a maximum frame rate. Audio and other settings may also be enforced.

## Web presets
HandBrake's web `Presets` use the broadly compatible [MP4 container](https://en.wikipedia.org/wiki/MPEG-4_Part_14) and are tailored for sharing videos on the Internet.
Gmail `Presets` are designed to guarantee video up to a certain duration will produce a file less than 25 [MB](abbr:megabytes) for attaching to an email.[^email-size-limit] The maximum duration is part of each `Preset` name. Audio quality is slightly reduced, and visually noisy/grainy or high motion scenes may show a reduction in quality in order to achieve the target file size.

[^high-quality-settings-less-compatible]: Higher quality general `Presets` may include settings that are incompatible with older or slower devices.
[^email-size-limit]: The 25 [MB](abbr:megabytes) per message size limit for email attachments is specific to the [Gmail](https://www.google.com/gmail/) service and may change in the future. Other email services may set different limits. It is generally recommended to use a [file hosting service](https://en.wikipedia.org/wiki/Comparison_of_file_hosting_services) when sharing large or long videos.
