Every “free” file converter online = your files sent to some random server.

So I made my own. Runs locally as an app on Mac, Windows and Linux.

Now 1,100 users use it for 3,742 types of conversions.
This month my side project made $4,000 in a single day

How to Convert has a new update!

It includes a new auto-update checker, which will notify you if there is a new version of the app available (no longer will you have to check manually or look out for these posts!).

It also includes professional RAW camera formats and a bunch of...

I made an app that does 3,902 document, video, image, audio and email file conversions.

It does it all locally, not on some random website and it just crossed 1,600 users!

At the start of the year, I had less than $1,000 in the bank. I was desperately searching for work and building this app on the side.

Today that app made $4,000 in a single day!
I made an app that converts almost any file locally.

And it just had its best day of sales ever!

Just read this article about my file converter app! Thanks for the amazing review and spotlight!

It's brought in a surge of new audio engineer users, so I will be adding even more audio conversions to the app in the coming weeks.

Noticed a big spike in sales today. Seems to be thanks to a recent article featuring my file converter app, How to Convert.

Really appreciate the spotlight and support!

I made $5,387 in October

$5,326 from How to Convert
$61 from Pictiler
$0 from my last failed project 🙈
$0 from the project before that 🤷‍♂️

Don’t give up. That next project could be the one that changes everything.
Building apps and websites is one of the best decisions I've ever made.

Made an app to convert almost any file locally.

And now it has adjusted pricing for 95+ counties (depending on purchasing power)

Just rolled out localised pricing across 95+ countries!

Now everyone can access the app at a fair price for their region

Microsoft just launched Mico and hit the top of Product Hunt

Aaaaannd all the comments are AI bots

I’ve heard people say Product Hunt is pay to win. Now I believe it.
You seriously can’t detect bot votes and comments that obvious?

Not all projects work out.

Just shipped some usability updates 🚀

1. The app now resizes to smaller windows
2. You can set your save location before converting (super helpful for big files)

🧛‍♂️ Don’t let your files get sucked into the cloud.

Convert them safely on your device.

My app How to Convert is on sale for Halloween 👻

3,902 conversions supported.
