Frequently asked questions
The fine print, minus the fog.
Short answers about privacy, browser support, file handling, and offline installation.
How do I get started with preset.tools?
Getting started takes seconds. Open the dashboard, grant access to the folder where your Serum 2 presets are stored, and preset.tools will automatically scan and load every .SerumPreset file it finds.
What file formats does the Serum 2 preset editor support?
preset.tools works with .SerumPreset files, the native format used by Serum 2. Convert older .fxp presets inside Serum 2 first.
Can I use this app on mobile devices?
The interface is responsive, but the File System Access API is currently supported only in desktop browsers like Chrome, Edge, and Opera.
Can I edit presets from external drives and cloud storage?
Yes. Select any directory your operating system can see, including USB drives, network shares, and cloud storage mounted as a local folder.
What operations can I perform on my presets?
You can bulk edit metadata and tags, change authors, update categories, rename files with template patterns, and copy or move presets between folders.
Are my presets safe and private?
Absolutely. preset.tools operates entirely within your browser. Your presets never leave your machine, and you can create a ZIP backup before making changes.
How does the offline mode work?
preset.tools is a Progressive Web App that caches everything it needs in your browser. After your first visit you can use the editor without an internet connection.
