Questions & Answers

As answered by people managing Project Euler and Toolkiya.

Why should a person choose your product over its competitors?

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.

What's the story behind your product?

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.

How would you describe the primary audience of your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

Toolkiya's answer:

  • Students using rent receipt and resume builder for job applications
    • Freelancers generating invoices with logo and signature
    • Developers using JSON formatter, regex tester, and JWT decoder daily
    • Small businesses creating salary slips, bills, and receipts
    • Content creators compressing images and making QR codes

What makes your product unique?

Toolkiya's answer:

Everything runs in your browser. Unlike iLovePDF or SmallPDF, your files are never uploaded to any server. Plus there are no usage limits, no signup, and no
premium tier — all 85+ tools are completely free.
