Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Mariutil is a browser-based collection of utilities that its developer, Madhu, says is meant to bring common developer and everyday digital tasks together in one place. The project is described as under development; its listed tools and its approach to handling data should be treated as the developer’s account, not as a verified description of the current live service.
Why Mariutil was started
Madhu says the project grew out of repeatedly switching among separate websites for small jobs: formatting JSON, encoding data with Base64, converting PDFs, compressing images, or generating hashes. Mariutil’s stated aim is to make those kinds of tasks available through one browser-based toolkit. The developer frames the idea this way: “If a task can be safely and efficiently performed in the browser, why send the data to a server?”

That explains the project’s motivation, but it is not evidence of measured time savings or an independent evaluation of the service.

In the project article, Madhu describes Mariutil as a growing set of utilities for developers and general digital use. The examples fall into three broad groups:
Developer utilities
- JSON Formatter
- XML-to-JSON
- JSON Mock Generator
- Base64 Encoder/Decoder
- Hash Generator
- Password Generator
PDF utilities
- PDF Merge and PDF Split
- PDF-to-Text and PDF-to-JPG
- JPG-to-PDF
- PDF-to-CSV
- Word-to-PDF
Other digital utilities
- QR code generation and scanning, plus barcode scanning
- Screen recording and audio transcription
- Image compression and image resizing
These are tools named in the developer’s article, not a confirmed inventory of features that are currently available or working on the live site.
Does Mariutil process data locally?
The developer says the project aims to perform as much processing as practical in the browser. The article gives JSON processing, Base64 encoding and decoding, hash generation, image processing, some PDF operations, and some audio processing as examples where local handling may be possible. It also says the architecture depends on the tool.
That distinction matters: the project article does not establish that every utility runs locally, or that all data stays on a user’s device. Before using a tool with sensitive material, check its current, tool-specific privacy and processing information. The source for these descriptions is Madhu’s project article on DEV Community: “I Built Mariutil: A Browser-Based Toolkit for Developers and Everyday Tasks.”

What is—and is not—established
The available account establishes how the developer describes Mariutil’s purpose, examples of intended utilities, and preference for browser-local processing where feasible. It does not independently verify the current feature catalog, provide a technical audit of data handling, or report pricing, benchmarks, adoption, or user outcomes. Readers should therefore treat Mariutil as a project whose described scope is broader than what can be confirmed from that account alone.
