Original Summary

Hey everyone, I got tired of all the sketchy "free" image converters out there that upload your private photos to some random server, so I built my own: FormatFlash. The problem: I take a lot of photos on my iPhone (HEIC format), but I constantly need JPGs or PNGs for websites, clients, or just to open them in older software. The solution: FormatFlash is a fully client-side image converter. Your files never leave your device because everything runs in your browser using the Canvas API. What it does: • Converts HEIC/HEIF → JPG, PNG, WebP • Converts between JPG, PNG, WebP (any direction) • Has a quality slider so you can control compression • Shows a live preview before you download • Works completely offline after loading The tech: It's vanilla JS, heic2any for HEIC decoding, and the Canvas API for format conversion. Hosted on Cloudflare Pages, so it's fast and free. What I learned: I completely overestimated the importance of the tech and underestimated the importance of just shipping. The tool works, it's live, and I'm now figuring out the harder part: getting people to actually use it. Link: formatflash.com No signups, no email walls, no ads yet. I'd genuinely love feedback on what formats you'd want to see next or what's confusing about the current UI.   submitted by   /u/Other_Fun1919 [link]   [comments]
