LOVED BY MAKERS
Built for people who hate friction.
Designers, developers, and privacy nerds use ZerofyTools every day. No signup means we can't track them — but they keep coming back.
“Replaced three browser tabs and one paid SaaS subscription. The compressor alone shaved 60% off my asset bundle.”
“I run sensitive client photos through the EXIF stripper before every handoff. Knowing nothing uploads is the whole point.”
“Magic Lab detected my SVG, suggested optimize → strip metadata → convert. Saved me writing a node script.”
“Bookmarked the contrast checker. Loads in 200ms, no cookie banner, no upsell. Bliss.”

Frequently Asked Questions
How is it so fast?
We don't use backend servers. By leveraging WebAssembly and HTML5 Canvas, your browser's CPU does all the heavily lifting instantly.
Do you store my uploaded images?
No. It is impossible for us to store your images or data because they are never transmitted across the network in the first place.
What's the catch? Why is it free?
We built this tool suite because we were tired of encountering paywalls for simple utilities. It's free because running client-side apps costs us virtually nothing in server fees.
