Frequently Asked Questions — SwiftPDFKit FAQ
Have questions about SwiftPDFKit? Find detailed answers below regarding file security, tool usage, browser support, and how we keep our platform free for everyone.
Is SwiftPDFKit really free?
Yes, all our tools are 100% free to use. There are no hidden fees, no subscription requirements, no premium-only tiers, and we never insert watermarks onto your processed documents. We fund our servers and infrastructure through clean display ads.
Are my files safe? What is your retention policy?
Absolutely. We follow a strict Zero-Retention Policy. All uploaded files are processed strictly in volatile server RAM and permanently deleted from memory the instant your download starts. Files are never written to physical hard disks, leaving no trail behind. Local tools like PDF to JPG process files entirely in your browser sandbox using WebAssembly, meaning your files never cross the network.
Do I need to sign up or create an account?
No. SwiftPDFKit requires no sign-ups, no registration, no email addresses, and no personal profile information. You can access all of our utility features immediately upon visiting the site.
What is the maximum file size supported?
We support document uploads up to 50 MB per file, which covers the vast majority of personal, financial, academic, and business documents. If you have files larger than this, you can optimize or split them before uploading.
Which operating systems and browsers are supported?
SwiftPDFKit is compatible with all modern browsers (Chrome, Firefox, Safari, Edge, Brave, Opera) on desktop and mobile operating systems (Windows, macOS, Linux, iOS, Android). No plugins or extension installs are required.
How does the PDF to JPG converter work locally?
Our PDF to JPG converter utilizes client-side WebAssembly rendering. When you upload a document, your browser parses the pages locally and exports them as JPG files. Since it runs client-side in your browser cache, it operates without server network bandwidth and is completely secure.
