Why UZPDF
A tool, not a trap
No sign-up walls, no watermarks, no upload limits hidden behind a paywall. A small, honest toolkit for everyday PDF work.
Your files never leave your device
Every operation runs in your browser. Your documents are never uploaded, stored, or seen by us — there's nowhere for them to go.
No queue, no waiting room
Since nothing travels to a server, there's no upload time and no processing queue. Results appear as fast as your device can produce them.
Works after the first load
Once a tool has loaded, the processing runs offline. Drop a file on a plane or with no signal — it still works.
Free, no account
No registration, no card, no email. Open a tool and use it. That's the whole deal.
Questions
Frequently asked
01Are my files uploaded to a server?
No. Every UZPDF tool runs entirely inside your browser. Your PDFs and images are read into memory on your own device, processed there, and saved back to you. Nothing is sent to us or any third party.
02Is UZPDF really free?
Yes. Every tool is free — no account, no watermark, no hidden upload limits. UZPDF is offered as a simple public utility for working with PDFs.
03What's the maximum file size?
There's no fixed server limit, because processing is local. The practical limit is your device's memory — very large files (hundreds of pages) may be slow on older phones, but typical documents are instant.
04Can I use UZPDF offline?
Mostly, yes. Once the page and the tool have loaded, the PDF processing runs without an internet connection. You only need to be online to open the site the first time.
05Does merging or rebuilding a PDF reduce quality?
No. UZPDF rewrites the file structure without re-compressing your images, so the visual quality of your pages is preserved. We never silently degrade your content.
06Which browsers are supported?
UZPDF works in any modern browser — recent Chrome, Firefox, Safari and Edge, on desktop and mobile. No extensions or plugins needed.
