@Luddosaurus true, I just improved the supported conversions list, so hopefully people like the new look 👀

😅 Just improved my website load time on mobile by 100x

Was because I was loading each conversion my file converter can do (over 3000) on page load.

Did I add too many file conversions?

Today marks my best day on Google ever!

Thanks for supporting my local file converter app howtoconvert.co!

Check it out at howtoconvert.co

It runs on Mac, Windows and Linux.

I made How to Convert, so you never have your files stolen by some random online converter you found on Google again.

It's an app that does almost any document, video, image and audio conversion locally. No files ever leave your computer.

There are plenty of file conversion sites, but when you use them, you’re sending your files and data to their servers.

I didn’t like that. The alternatives are command-line tools that run locally.

I wanted to use these tools but with a drag-and-drop app so non-programmers could use it.

How to Convert does over 3000 document, video, image and audio conversions and you can get it at
howtoconvert.co

I originally posted this here

and received an amazing response, got about 30 feature requests and I've been adding features since. This update adds almost 1000 conversions.

I made howtoconvert.co

It’s a universal file converter that performs conversions locally on your device.

It does over 3000 document, video, image and audio conversions.
How? By letting you run multiple command-line file conversion tools from a simple drag and drop app (imagemagick, libreoffice, ffmpeg and pandoc).
You don't have to touch the command-line to use them.

2. Don’t wait for the perfect idea. Launch, listen, and be ready to pivot.

Best startup advice I’ve heard from the founders of twitch:

1. Start by building something people genuinely want.

You can now convert almost any file locally with howtoconvert.co

I added 3099 document, image, audio and video conversions

I just boosted that number by almost a 1000 by enabling multi-step conversions (combining multiple tools)
