I built a free image converter that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick image converter and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard image use cases (image, convert, png, jpeg) and links out to the formula + worked examples if you want to learn the math.
