Welcome to Toolora

Toolora is a small, opinionated tools site. 74 utilities at the time of writing — JSON formatters, image compressors, color pickers, calculators — all running inside your browser tab. No accounts. No email gate. No "free vs Pro" wall. The product you see is the whole product.

I started building it because I kept losing minutes per day to ad-stuffed, login-walled tool pages I trusted less than I'd trust a stranger with my JSON. So I built the version I wanted: every tool clears Lighthouse 95, every JS bundle stays under about 30 KB, and the Network tab in DevTools stays empty while you work. You don't have to take my word for that — open DevTools and look.

This post is the short tour. Below are five kinds of people who keep showing up in our analytics, and the three tools each of them would probably reach for first.

1. Students

Long writeups, formatted homework, citations.

Markdown to HTML Converter — paste lecture notes, get clean HTML you can drop into a class blog or LMS.
Word Counter — instant word, character, and reading-time count for essays with strict limits.
Image Compressor — shrink a 4 MB screenshot to under 500 KB before uploading to a portal that caps you at 1 MB.

2. Designers

Pixel-precise color, typography, layout.

Color Picker — sample, convert between HEX/RGB/HSL/LCH, copy in the format your design tokens expect.
Gradient Generator — build CSS gradients with live preview and copy-paste output that actually matches what you see.
SVG Optimizer — strip designer-tool cruft from exported SVGs, often cutting them 40–60% with zero visible change.

3. Developers

The unsexy stack of "I need this 12 times a week."

JSON Formatter — pretty-print, minify, validate. Loads in well under a second, even for 5 MB payloads.
Regex Tester — test patterns with live highlights and capture-group inspection. No, you don't have to install another VS Code extension.
JWT Decoder — paste a token, see the header and payload locally. The token never leaves your machine, which matters when it's a production token.

4. Content creators

Thumbnails, captions, cross-platform posting.

Image Resizer — generate the exact 1080×1080, 1920×1080, 1080×1920 variants the algorithms reward, all from one source file.
QR Code Generator — link to your channel, your Patreon, your shop. Download as PNG or SVG.
Markdown Table Generator — for the times "I'll just write this in Notion" turns into "I need this in five places."

5. Office / everyday

The "I work on a laptop and I need something that just works" crowd.

PDF to Image — extract a page from a 40-page PDF as a PNG without uploading the file to a service that may keep it.
Mortgage Calculator — model payments across rates and terms before you sign anything.
Unit Converter — meters/feet, kg/lb, °C/°F, with the kind of precision you'd want on an actual invoice.

How to make the most of it

Two habits that pay off:

Bookmark toolora.info. The whole point of an indie tools site is that you stop Googling for them. One bookmark replaces ten search results.
Email me when something is wrong. Real address, lilei961112@gmail.com, real human, no auto-responder. Bugs, missing features, "this number doesn't match Excel for X reason" — I read all of it.

That's the tour. If you've made it this far, you probably know one person who's been complaining about the exact tool site you replaced today. Send them the link.
