Simple Image Converter is a free, browser-based toolkit with 22 utilities for everyday file tasks — no signup, no installs, no watermarks.
Resize, crop, compress, and convert images. Turn PDFs into images or text. Test your mic, keyboard, mouse, or webcam. Generate QR codes, passwords, and dummy images. Convert to/from Base64. Grab YouTube thumbnails. All of it runs right in your browser.
Built solo, and still growing — new tools ship regularly based on what people actually need.
This is a great example of solving the “tiny problem that happens all the time” category.
I especially like that it’s browser-based with no signup or installs. For tools like image conversion, the friction of uploading files to some random website, creating an account, or dealing with aggressive ads is often worse than the actual task.
The “22 utilities in one place” approach also makes sense because once someone trusts you with one file task, there’s a good chance they’ll come back for another.
Curious how you’re deciding which tools to build next?
The “new tools based on what people actually need” part caught my attention.
What have users actually been asking you for so far that surprised you?
