Building the Future of
Online Tools
From PDF converters to image editors, we're making powerful tools accessible to everyone — without the paywalls, watermarks, or signups.
Who We Are
Zutilium brings everyday file tasks into one toolkit: convert documents, edit images, create GIFs, work with Markdown and read QR codes. Some tools process data in your browser; others upload files for server processing. Each tool explains its supported formats and limits, and our privacy policy describes temporary file handling.
Our Values
Clear File Handling
Browser tools such as Sprite Sheet to GIF and .htpasswd Generator process their inputs locally. Standard server conversions use temporary uploads and scheduled cleanup.
Practical Workflows
Choose the tool for your input, adjust its options and download the result. Processing time depends on file size, document complexity and server load.
