Our story
Built for people who care about privacy.
zeropng started with a simple frustration: every decent image tool required uploading your files to someone else's server.
The problem we're solving.
In 2024, we surveyed the landscape of online image tools. The results were disappointing: every major compressor, every format converter, every metadata stripper uploaded your files to external servers. Your vacation photos. Your product mockups. Your confidential documents that happened to be images.
The justification was always the same: “We need server-side processing for performance.” But that stopped being true around 2020, when WebAssembly became fast enough to run professional image codecs at native speeds inside a browser tab.
We built zeropng to prove a point: you can have professional-grade image tools that are fast, free, and private by architecture, not just by policy. When your files never leave your device, there's nothing to breach, nothing to sell, nothing to worry about.
Privacy by architecture
We don't have a privacy policy that restricts what we do with your data. We have an architecture that makes data collection impossible.
Completely free
No subscription, no account, no hidden fees. ZeroPNG is free to use for personal and commercial projects.
Same engines as the pros
We use libpng, libjpeg-turbo, libavif, and libwebp, the exact same codecs used in Photoshop and production image pipelines.
Works everywhere
No account, no installation, no internet required after first load. A PWA that works offline so your tools are always available.
By the numbers
The team
Built by people who love the web.
