Frequently asked questions
Common questions about how QuickZeta works, answered directly.
+Is QuickZeta actually free, with no hidden limits?
Yes. Every tool works with no sign-up, no daily usage cap, and no watermark on your output. The site is supported by ads rather than subscriptions, per-file fees, or a freemium paywall.
+Do you upload or store my files anywhere?
No. Every tool processes your file directly inside your own browser. Nothing is uploaded to a server, which means we never see, store, or have access to whatever you're working on.
+How is this different from sites like Smallpdf or iLovePDF?
Those sites upload your file to their servers to process it, even if they delete it shortly afterward. QuickZeta never uploads anything at all — the processing happens locally, on your own device, using the same browser capabilities that power the page itself.
+Why do some tools take a moment to load the first time?
A few of the more advanced tools — background removal, PDF compression, video and audio conversion — load a specialized processing library the first time you open them, rather than bundling it into every page load. It's a one-time download per browser session; your files still never leave your device.
+Will these tools work on my phone?
Yes, the whole site is responsive and works in any modern mobile browser. Heavier tools like video trimming will naturally run slower on an older phone than on a desktop, since your own device is doing all the processing.
+Do I need to create an account?
No. There's no login, no email required, and nothing tied to an account — open any tool and start using it immediately.
