Built differently from iLovePDF, Smallpdf, and PDF24

These competitors upload your files to their servers — every single one. SmartApplets is built so we cannot.

Provably private

Open Chrome DevTools → Network tab while using any tool. You will see no upload of your PDF — because it never leaves your browser.

Instant results

No upload queue. No server round-trip. Tools run on your own CPU, so most operations finish in under 2 seconds — even on large PDFs.

Truly free, no tricks

No daily limit, no watermarks on output, no "2 free files per hour" cap. Every tool, every feature, for everyone, forever.

Works offline

After the first visit, tools are cached in your browser. You can use them on a plane, in a tunnel, behind a corporate firewall — anywhere.

Mobile-first design

Every tool is designed for one-thumb operation on a phone. Large touch targets, scrolling lists, no tiny desktop-only buttons.

Open-source engine

Built on pdf-lib and PDF.js — open-source libraries trusted by hundreds of major apps. No proprietary "black box" between you and your file.

Frequently asked questions

Honest answers about how the tools work and their limits.

Are SmartApplets PDF tools really free?
Yes, completely free for everyone. No daily limits, no watermarks, no paid tiers, no sign-up. The site is supported by clearly-labelled Google AdSense ads on the page itself, not by limiting the tool.
Do you upload my PDF files to a server?
No. Every PDF tool on SmartApplets runs entirely in your browser. There is no server we use to process your files. You can verify this by opening your browser's Developer Tools to the Network tab and watching for any upload activity — you will see none.
What's the file size limit?
There is no hard limit imposed by us, only your device's available memory. Most modern computers handle PDFs up to 500 MB easily. On phones, expect comfortable handling up to about 100 MB. Larger files may slow down but will not be rejected.
Do the tools work on mobile?
Yes — all 11 tools are designed mobile-first with large touch targets and responsive layouts. They work on iPhone Safari, Android Chrome, and any modern mobile browser. Performance is competitive with desktop on flagship phones; older phones may take a few extra seconds on large files.
What happens if I use a tool offline?
All tools work offline after the first visit. The tool's code is cached in your browser. You can drop a PDF, process it, and download the result with no internet connection — useful on planes, trains, or low-connectivity areas.
Why should I trust SmartApplets with confidential PDFs?
Don't trust us — trust your browser. Every tool's privacy claim is technically verifiable in your browser's Network tab. There is no upload request because the JavaScript code that processes your PDF runs locally on your machine. We could not access your files even if we wanted to.
