30+ free PDF tools. No ads, no installs, files autodeleted - Konomic

Hi everyone! I'm Nikita, the maker of Konomic 👋

I built this because I was tired of paying $15/month just to merge two PDFs.

The existing free tools are slow, showing ads everywhere, and keep your files

on their servers forever.

Konomic fixes all three:

🎯 Key features I'm most proud of:

• PDF Editor with TrueEdit — click any text in a PDF and retype it inline

(not a text-box overlay, actual text replacement). Most tools paywall this.

• E-Signatures — send, sign, download. Signers don't need an account.

Full audit trail, eIDAS-compliant.

• AI Chat + Summarize — ask questions about any PDF in natural language.

No extra cost.

• Privacy-first — files auto-delete in 1 hour, EU-only servers, GDPR compliant.

Never trained on your files.

💰 Pricing: Free tier covers 20 ops/day. Pro is $4.99/mo (vs Adobe $20/mo).

🛠 Tech stack: Next.js 16, FastAPI, PostgreSQL, Celery, PyMuPDF, pdf.js,

Tesseract OCR. Solo-bootstrapped, deployed on a single Hetzner VPS.

Bonus: a GDPR-compliant contract generator (NDA, freelance, privacy policy)

pre-tuned for ES/DE/FR/EU jurisdictions. Freelancers — check it out.

Would love your feedback — what PDF tools do you use daily?

And what's missing from free alternatives that made you go paid?
