Frequently asked questions
Is PDFOtter really free?
Yes. Every tool is completely free with no sign-up, no watermarks and no hidden limits. We keep the lights on with unobtrusive ads.
Are my files safe?
Absolutely. All processing runs locally inside your web browser using JavaScript. Your PDFs are never uploaded to any server, so nobody, including us, can see them.
Is there a file size limit?
There's no artificial limit. Because everything runs on your own device, the only limit is your device's available memory.
Do I need to install anything?
No. PDFOtter works entirely in your browser. Just open a tool and go.
