I built a collection of simple online tools because most tools are overcomplicated

Most online tools today feel… heavier than they should be.

You open a simple JSON formatter or CSV converter and end up dealing with:

  • slow loading times
  • cluttered interfaces
  • unnecessary features
  • or even login walls for basic functionality

All of this just to complete a task that should take a few seconds.

So I decided to build something different.


The idea: tools that do one thing well

Instead of creating a big “all-in-one” platform, I started building small, focused tools — each designed to solve a single problem:

  • format JSON
  • convert CSV ↔ JSON
  • clean up text
  • process images

No extra steps. No feature overload.

Just pick a tool, use it, and move on.


What I focused on

1. No signup, ever

You shouldn’t need an account to format text or convert a file.


2. Speed over features

Most tools don’t need 20 options — they need to be fast and reliable.


3. Clean UI

Minimal interface, no distractions, no ads everywhere.


4. Privacy-first approach

Whenever possible, tools run directly in your browser.

For file-based tools:

  • files are only processed for the task
  • automatically deleted within a short time window
  • not stored or reused

What I’ve built so far

The project is called ConvertWiki:
https://convertwiki.com

Right now it includes tools for:

  • JSON formatting & validation
  • CSV / JSON conversion
  • text cleanup (like removing duplicates or line breaks)
  • image processing

It’s still early, but the goal is to keep expanding based on real use cases.


Why I’m sharing this

I know there are already a lot of tools out there.

This isn’t about reinventing everything — it’s about making common tasks simpler and less frustrating.


I’d love your feedback

If you use tools like these:

  • what annoys you the most?
  • what’s missing?
  • what would you improve?

I’m building this iteratively, so feedback really helps shape what comes next.
