Hey Product Hunt! I'm Gaurav, the maker of MiniPx. I built this because every image compressor I tried uploaded my files to a server. That felt wrong for something as simple as shrinking a JPEG. So I built one that runs entirely in your browser using the Canvas API. Your images never leave your device. What started as a single compression tool grew into 83 free tools — covering JPEG, PNG, WebP, HEIC, and PDF. There are purpose-built tools for passport photos, government form uploads, WhatsApp sharing, and more. The entire frontend is 103KB of JavaScript. No backend, no accounts, no limits. Just open the site and compress. I'd love to hear what you think — and what tools or formats you'd want to see next.

I built MiniPx because I got paranoid about image unloaders

I was compressing passport photos for a visa application last year. Halfway through, I stopped and thought where are these actually going?

Checked the privacy policy of the tool I was using. Buried in paragraph 14: "uploaded files may be stored for up to 24 hours for processing purposes." My passport photos sitting on someone's server. Cool.

That bugged me enough to start building something. MiniPx runs entirely in your browser - Canvas API handles the compression, your files never hit a server. There's no upload step at all.

It started as a weekend project and kind of snowballed. 83 tools now, still free, no signup.
