Every time you compress an image on TinyPNG, convert a PDF on iLovePDF, or remove a background on remove.bg — your file gets uploaded to someone else's server.

Most people don't think twice about it. But here's what's actually happening:

• Your file travels over the internet to an unknown server

• It sits there for anywhere from 15 minutes to 24 hours

• You have zero control over what happens to it after processing

• Third-party involvement in data breaches doubled to 30% in 2025 (Verizon DBIR)

I'm a developer. I was tired of this. So I built ZerofyTools — 26+ free browser-based tools that process everything locally. Image compression, background removal, JSON formatting, PDF compression, color picking — all of it runs in your browser using WebAssembly. Nothing leaves your device. Ever.

No signup. No file uploads. No limits. No BS.

I use these tools every single day for client work. If you're a freelance designer or developer, you probably will too.

Check them out at zerofytools.com — every tool is free, forever.

And if you want batch processing, max quality exports, and early access to new tools — that's what ZerofyTools Pro is for.
