About ConvertInSeconds

ConvertInSeconds is a free online file converter built and operated by Artoption GmbH, a software company based in Hamburg, Germany. Our goal is simple: converting a file should take seconds, not require registrations, installations or paid subscriptions.

What we believe in

• Free means free. No watermarks, no forced sign-ups, no "premium" paywall for basic conversions. The service is financed through advertising.
• Privacy first. Wherever technically possible, conversions run directly in your browser and your files never leave your device. Server-side conversions travel over encrypted connections and files are deleted automatically after processing.
• No bloat. Every converter does one thing and does it fast — on desktop and mobile alike.

Our tool family

ConvertInSeconds is part of a growing family of free web tools made in Hamburg, including BiGimg (image editing tools), CropInSeconds (social media image cropping) and Zugpferd (e-invoice viewer). Building and running these tools every day is where our experience with file formats and conversions comes from.
