Frequently Asked Questions
Are these PDF tools really free?
Yes — completely. Every tool on Skilltosky PDF Tools is free to use with no registration, no subscription, and no hidden fees. There are no daily limits or watermarks.
Are my PDF files kept private?
Absolutely. All PDF processing happens entirely inside your browser using JavaScript. Your files are never uploaded to any server — they stay on your device at all times, even for operations like editing, signing, merging, and rotating. The one exception is PDF to Word, which uses a secure third-party service for accurate document formatting; files are deleted immediately after conversion.
Do I need to install anything?
No. Skilltosky PDF Tools works entirely in your web browser — no software download, no app, no browser extension required. Just open the page and start working with your PDFs. If you'd like quicker access, you can optionally install it as an app on your device — it still runs the same way, just without the browser address bar.
Which browsers and devices are supported?
All modern browsers are supported — Chrome, Firefox, Edge, Safari, and Opera — on desktop, tablet, and mobile. No plugins or extensions are required.
Can I edit or sign encrypted PDFs?
Yes. Encrypted and password-protected PDFs are handled automatically. The tool detects encryption and uses a high-quality browser-based rendering path so you can still edit, sign, and export them.
Is there a file size limit?
Since files are processed locally in your browser there are no server-imposed size limits. Very large files may be slower depending on your device's memory and processing speed.
