As answered by people managing PixMidas and Cert Decoder.
PixMidas's answer
PixMidas started from a simple frustration: every time you need to compress an image or merge a PDF, you end up on a site that demands an account, slaps a watermark on your file, or quietly uploads your documents to a remote server. We wanted to build the opposite. A clean set of tools that respect your time and your files. Everything runs locally on your device, the interface stays simple, and there is no hidden agenda. The name comes from the Midas touch: the idea that your files get exactly what they need, instantly, without the baggage.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
PixMidas's answer
Astro and React for the frontend, deployed on Cloudflare Pages. All file processing uses browser-native APIs including Canvas API, WebAssembly, and JavaScript libraries that run entirely client-side. No backend servers process user files. The architecture is designed so that the tools work even offline once the page has loaded.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
PixMidas's answer
Anyone who regularly handles images, PDFs, or text files and wants a fast, private way to get things done without installing software or creating accounts. This includes freelancers preparing client deliverables, small business owners compressing files for email, content creators resizing images for social media, developers generating favicons or QR codes, and privacy-conscious users who do not want their documents uploaded to third-party servers.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PixMidas's answer
Privacy without compromise. Most competitors upload your files to their servers, process them remotely, and delete them later. PixMidas never sees your files at all. Everything runs in your browser using client-side processing. Beyond privacy, there are no account requirements, no watermarks on output, no artificial file size limits, and no usage caps. You open a tool, use it, and download the result. That simplicity is rare in a space full of signup walls and upsell traps.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
PixMidas's answer
PixMidas is used by individual professionals, freelancers, and small teams. We do not track or identify users by design, which is core to our privacy-first approach.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PixMidas's answer
Every tool runs entirely on your device. Unlike most online tool platforms that upload your files to remote servers for processing, PixMidas uses browser-based technology to process everything locally. Your files never leave your device. This means faster processing, no file size limits imposed by a server, and genuine privacy. There is no account wall, no watermark, and no upload queue.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
