As answered by people managing StackSource and Konomic.
Konomic's answer:
Konomic combines 30+ PDF tools and image tools (background removal, image compression, AI upscaling, passport photo preparation, OCR) in a single browser-based product. It is built privacy-first: files are encrypted in transit, deleted within 1 hour, never used for AI training, and processed on EU-based servers under GDPR. Basic tools are free without an account, and the paid plan covers everything at $4.99/month instead of separate subscriptions for a PDF editor, e-signature service, and image tools.
Konomic's answer:
Pricing and privacy. Pro at $4.99/month includes the full toolset — editing, conversion, e-signatures, OCR, AI chat with PDFs — where competitors typically charge $9–25/month for narrower functionality. Files are auto-deleted within an hour and never shared or used for training, which matters for contracts and personal documents. The free tier is usable without a credit card and lets you test every tool, including AI features.
Konomic's answer:
Freelancers, consultants, and small businesses that handle documents daily — invoices, contracts, NDAs, proposals — and want one affordable tool instead of a stack of subscriptions. Also privacy-conscious users and EU-based companies that prefer GDPR-compliant, EU-hosted processing for their files.
Konomic's answer:
Konomic is built by Konomic Digital SL, a software company from Tenerife, Spain. It started as a set of internal PDF utilities and grew into a public product after it became clear that most popular PDF services are either expensive, ad-heavy, or unclear about what happens to uploaded files. The goal is a complete document toolkit that is fast, affordable, and transparent about privacy.
Konomic's answer:
Python with FastAPI on the backend, PostgreSQL, and Docker-based processing workers. OCR is powered by Tesseract 5 with support for 100+ languages. All processing runs on EU-based infrastructure.
