I built a drag-and-drop app that converts almost any file to any other file. It now supports almost 4,000 video, image, audio, document and email file conversions. And I just crossed 2,250 users!

I’m building a universal file conversion app solo. It converts almost anything: documents, videos, images, audio, even email files. I just shipped a new feature I wanted myself: an audio trimmer. Now you can take any video or audio file, cut out the exact part you need, and export it instantly.

I love this story from when @amazon was a small startup: In 1995 one of their first international orders came from a customer in Bulgaria. The buyer didn’t have a credit card, so instead shipped them a floppy disk.

Haven't yet tried Perplexity AI before. But it's recommending my app to people, so thank you!

Sorry claude 😟

When you know you’re going to have a productive day

1 year ago, I made an app that converts almost any file to any other file locally Today, over 2,200 people in 77 countries are using it. 🇺🇸 🇬🇧 🇩🇪 🇦🇺 🇨🇦 🇧🇷 🇳🇱 🇫🇷 🇮🇹 🇪🇸 🇲🇽 🇨🇭

I’ve been working on my file converter app How to Convert for a year now Here’s what it does: → 3,985 video, image, audio, email & document conversions → Files never leave your computer. Runs 100% locally → Works on Mac, Windows, and Linux

Used this a few times, it's great. Now where do I get a real alternative to Google Docs and Sheets?

Got a Kindle Colorsoft (colour e-ink) and it’s amazing. About 4 years ago I remember repeatedly looking up when colour e-ink was coming out. A reflective screen is so much better on the eyes for reading. Amazon have changed to colour well! Currently reading My Indie Book by @tdinh_me and loving it

Spent some time updating my browser-only photomosaic generator. Fast, private, no signup. pictiler.com

I use alternativeto.net all the time when I search "alternative to X" Amazing to see my app in one of their posts!

A universal file converter that runs locally on your device and doesn't send your files to sketchy servers

I built a Mac and Windows app that lets you convert almost any file locally. It's all built by 'lil ol me me, in Perth, Western Australia. To celebrate Australian day 🇦🇺, it's 15% off!

I was tired of sending my files to random sites just to change formats. So I made an app that converts everything locally. Just added this new audio and video trimmer to it

Marketing done for the day ✅

I built a PDF compressor that runs 100% locally. Every popular option (SmallPDF, iLovePDF) uploads your files to their servers. Worse: they all use the same service behind the scenes anyway (pdf-tools). I wanted drag → drop → done, on my own machine. So I shipped it.

Just spent the day adding better error handling to my file conversion app

My research is actually being read 🥹 Already cited by 5!

This month over 2,200 people typed how to convert some file into another file on Google But this time they converted their files using a website that runs completely on their device (no files leave your web browser) So long sketchy file conversion sites that send your files to who knows where 🫡 👋

Some intel I need for the next app: Do you use screen studio or a screenshot app like Cleanshot X? If so, what don’t you like about it? Obviously price is a big one

I’m officially living completely off my app AND here’s my last 9-5 pay check 👇 I’ve been building completely solo for a year and it’s been scary, BUT just me reaching out here, on reddit and everywhere else I could has built a community of over 2,200 customers who want to support me.

I made an app to convert almost any file to any other file locally. Just crossed 2200 users!

Testing out a new hero message for How to Convert 🤞 Which do you prefer and why?

“Free” file web converters you find on Google aren’t free. You’re paying with your data. Mine works 100% locally. Nothing uploaded. Ever. 8 hours left to grab 15% off for Christmas

This 2025 I had 108,104 website visitors! Last year today I started working on this project. It came after years of failures. Moral of my story: Don’t stop building!

Every “free” file converter online = your files sent to some random server. So I made an app. Runs locally on Mac, Windows, Linux. Does 3,985 file conversions. And it's 15% off for Christmas! 🎅

I made a desktop app that converts almost any file to any other file locally. Crossed 2025 users this 2025!

10 months ago I launched a file converter app from my laptop. Today people in 77 countries are using it. 🇺🇸 🇬🇧 🇩🇪 🇦🇺 🇨🇦 🇧🇷 🇳🇱 🇫🇷 and 69 more… I built this while finishing my PhD, coding in cafes in Australia and recently across Europe. No VC funding. No team. Just solving a problem people actually have.

I go in cycles of using different task management tools Now I just use a text file with: TODO - [x] fix startup bug - [ ] add pdf compression feature - [ ] nice work. get a coffee Anyone else?

Got my lighthouse website performance score to 100! Look out competitors on Google! (Looking at you CloudConvert) 😏

I made an website to make photomosaics locally on your computer And it just crossed $200 in sales Thanks for supporting my little project!

Another article added to How to Convert's "as seen on" section. And it's a ripper of a review! If you're a audio or sound engineer, my file conversion app got into a Production Expert post! You can read it here: www.production-expert.com/production-...

I made a website to make photomosaics locally on your computer Instead of spending $100s for a print shop to do it, you can make them free And optionally spend $9 to get a high detail print-ready version when you're happy with it

Australia just enforced its social media ban for under 16s Good or bad decision? I'm curious what the tech bluesky thinks www.reuters.com/legal/litig...

My local file-conversion app started with roughly 2,000 supported conversions. It now handles nearly 4,000 document, video, image, email and audio conversions! All processed offline on your device for speed and privacy. Available on Mac, Windows and Linux.

I'm a solo developer that made an app to convert almost any file locally This month I crossed 2,000 paying users 🍾

2,000 people are now converting files locally without uploading them to random servers. When I launched How to Convert 10 months ago, I wasn’t sure if others wanted a locally Swiss Army knife like conversion tool. Turns out a lot of you do.
