As answered by people managing CodeSignal and Toolkiya.
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.
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.
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.
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.
