WHY_SLAYTIC
Built different from most "free" tool sites
privacy
Nothing ever uploads
Every tool runs as client-side JavaScript and WebAssembly. Your files are processed on your own hardware, never sent to a server.
cost
Actually free, no limits
No subscriptions, no per-file caps, no watermark holdbacks. All 236 tools are free to use as much as you need.
speed
Fast, because it is local
No round trip to a server means no upload wait and no queue: results appear as soon as your browser finishes processing.
access
No account required
Open a tool and start working immediately. No email, no sign-up, no password to remember.
WHO_ITS_FOR
Built for the everyday paperwork of running independently
Slaytic Converter started as a way to handle client files without routing them through a third-party server. It's grown into a full toolkit for the small, recurring tasks that eat up time between the actual work.
Freelancers & agencies
Merge client deliverables, sign contracts, and compress final assets before handoff, all without a client file ever touching a third-party server.
Students & educators
Convert assignments between formats, extract text for citations, and combine handouts into a single reading packet for class.
Small business teams
Protect invoices with a password, watermark shared documents, and keep bulk file cleanup off the IT team’s plate entirely.
COMPATIBILITY
Works in any modern browser, on any device
Every tool runs on standard web APIs available in Chrome, Firefox, Safari and Edge, on desktop or mobile. There's nothing to install: the toolkit works the same on a work laptop as it does on a phone during a commute.
