06 / good to know
Quick answers to the most common questions about FreePDFKit.
Yes — every tool is free with no usage limits, no premium tier, and no account required. The site is sustained through non-intrusive ads.
All processing runs locally in your browser. Files are never uploaded to a server. We have no access to your documents — there is no backend endpoint that receives files.
You can convert between PDF and Word (DOCX), Excel (XLSX), PowerPoint (PPTX), JPG, and PNG. Additional formats are planned based on user feedback.
No. The tools run in any modern browser (Chrome, Firefox, Safari, Edge). No plugins, extensions, or desktop software required.
Processing happens in your browser, so the real limit is available RAM. For most PDF tools we allow up to 256 MB per file on typical desktops; on devices reporting low memory (often phones), the cap is lowered to 128 MB to avoid crashes. Huge PDFs can still fail if the tab runs out of memory.
Yes. The interface is fully responsive and all tools work on mobile browsers. Large files may be slower on phones due to hardware constraints.
Everything runs in your browser on your device — the same place you already trust for banking and email. There's no separate cloud step, no queues, and no one else's servers in the middle.
Absolutely. There are no restrictions on commercial use. The same privacy guarantees apply — your business documents never leave your device.
