I Built a Free Online Tools Website with Next.js — Here’s What I Learned
A few weeks ago, I started building a project called Toolifyx — a free online tools platform that combines image tools, PDF utilities, text tools, and productivity tools in one place.
The idea was simple:
Most “free tools” websites are either:
- overloaded with ads,
- painfully slow,
- or filled with popups and unnecessary redirects.
I wanted to build something cleaner, faster, and modern using Next.js.
Why I Built It
I’ve always liked utility-based websites because they solve real problems instantly.
Sometimes people just need to:
- compress an image,
- merge a PDF,
- resize a file,
- count words,
- or generate an invoice quickly.
No account.
No signup.
No complicated UI.
So I decided to build an all-in-one platform where these tools could exist under the same design system and infrastructure.
Current Tools on Toolifyx
Right now the platform includes:
- Image Compressor
- Image Resizer
- Background Remover
- PDF Merge
- PDF Split
- PDF Compress
- Word Counter
- Resume Builder
- Invoice Generator
I’m planning to keep expanding it over time.
Tech Stack
The project is built mainly with:
- Next.js
- TypeScript
- Tailwind CSS
- Client-side file processing where possible
One important goal was keeping the UI lightweight and responsive.
I didn’t want pages filled with unnecessary JavaScript or animations that hurt performance.
Biggest Challenge: SEO
Honestly, the hardest part wasn’t coding the tools.
It was SEO.
When you launch a brand-new domain, Google basically doesn’t trust you yet.
I ran into:
- sitemap issues,
- canonical URL problems,
- redirect indexing problems,
- favicon caching issues,
- and pages staying in “Discovered – currently not indexed”.
I learned very quickly that building the product is only half the job.
Getting Google to properly crawl and trust your site is a completely different challenge.
Performance Optimization
One thing I cared about heavily was speed.
I tried to:
- optimize metadata,
- reduce unnecessary rendering,
- improve page structure,
- and keep tools accessible with minimal friction.
A lot of utility sites become bloated over time, so I’m trying to keep Toolifyx fast from the beginning.
UI/UX Decisions
I wanted the design to feel:
- simple,
- modern,
- and distraction-free.
Most users visiting tool websites want to complete a task quickly.
So instead of adding fancy complexity everywhere, I focused on:
- clarity,
- spacing,
- readability,
- and mobile responsiveness.
What I Learned
A few lessons from this project so far:
1. SEO takes patience
You can do everything correctly and Google may still take weeks to index pages.
2. Small technical issues matter a lot
Things like redirects, canonical URLs, sitemap formatting, and metadata can heavily affect indexing.
3. Utility products are fun to build
You get instant feedback because users immediately understand the value.
4. Shipping is better than overthinking
I delayed launching at first because I wanted everything “perfect”.
Launching early was the better decision.
Final Thoughts
This project is still growing, but it has already taught me a lot about:
- technical SEO,
- product structure,
- performance,
- and building tools people actually use.
If you’ve built something similar, I’d love to hear what challenges you faced.
