As answered by people managing Cert Decoder and Toolkiya.
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.
Toolkiya's answer:
Built as a solo side project in India on a budget under $25/month. I was frustrated that every free tool site had hidden limits or uploaded my files. So I built one where everything processes locally in the browser. Started with 10 PDF tools, now at 85+ covering PDF, image, AI, developer, and document tools.
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
Toolkiya's answer:
Next.js 16 (App Router), TypeScript, Tailwind CSS, shadcn/ui, pdf-lib, pdfjs-dist, Tesseract.js for OCR, Web Audio API, Canvas API. Hosted on Vercel. AI powered by OpenRouter free models with Gemini and Groq fallback.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Toolkiya's answer:
Students, freelancers, small business owners, and developers who need quick online tools daily — compress a PDF, resize an image, generate an invoice, format JSON — without paying for subscriptions or uploading sensitive files to third-party servers.
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.
Toolkiya's answer:
No file uploads (100% private), no account needed, no daily limits, and no paywalls. Competitors like SmallPDF give you 2 free conversions then ask you to pay. Toolkiya has zero restrictions. It also includes AI features like resume rewriting and an AI assistant at no cost.

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
