Why Slate is different
Most "online PDF" sites upload your documents to their servers. Slate never does — and that changes everything.
🔒 Truly private
Slate never uploads your files. Processing happens on your device with WebAssembly, so your documents stay yours — always. Even sensitive contracts and IDs are safe.
⚡ Instant results
No upload, no download queue, no server round-trip. Files are processed locally, so even large documents finish in seconds — not minutes.
🆓 Free, no limits
Every tool is free with no signup and no daily caps. Unlike Smallpdf's 2-task limit, Slate has zero restrictions. We keep the lights on with non-intrusive ads.
🌍 Works offline
Once the page loads, most tools keep working without a connection. Install Slate as a PWA for one-click access from your home screen.

Frequently asked questions
Everything people ask before trusting an online PDF tool.
Is Slate really free?
Yes — every tool is free with no signup, no daily limits, and no watermarks. Slate is funded by unobtrusive display ads, not subscriptions or selling your data.
Are my files uploaded anywhere?
No. Every Slate tool runs entirely in your browser using WebAssembly. Your files are read into local memory, processed on your device, and handed straight back to you — nothing is ever uploaded.
Do I need to create an account?
Never. There are no accounts, no email required, and no login. Open a tool and use it instantly.
Does Slate work offline?
Yes. After your first visit, Slate installs a service worker so the tools keep working without a connection. You can also install it as an app from your browser.
What's the file size limit?
There's no fixed limit — Slate is bounded only by your device's available memory, since processing is local. Most people can handle very large PDFs that would be rejected by upload-based sites.
How does Slate compare to Smallpdf or ILovePDF?
The key difference is that Slate never uploads your files. Smallpdf and ILovePDF both process files on their servers. Slate also has no daily limits, while Smallpdf limits free users to 2 tasks per day. See the full comparison table.
Is Slate a good free alternative to Adobe Acrobat?
For everyday tasks — merging, splitting, compressing, converting, rotating, watermarking — yes. Slate covers all the common PDF jobs for free, with no subscription required.
Is it safe to use Slate for confidential documents?
Yes. Because Slate processes everything locally in your browser, your files never leave your device. There's no server to breach, no data to leak. It's the safest way to handle sensitive PDFs online.
Ready to work with PDFs the right way?
