Are my files uploaded to your servers?
No. All processing happens entirely in your browser. Your files never leave your device and are never uploaded to our servers or any third party. This is the core difference between PDFinsert and most online PDF tools.
Do I need to create an account?
No. Every tool is available immediately — no registration, no login, and no personal information required.
Is PDFinsert really free?
Yes. All tools are completely free with no hidden fees, daily limits, premium restrictions or usage quotas. We believe useful PDF tools should be accessible to everyone.
Do you add watermarks to my files?
No. We never add watermarks, logos or branding. The files you download are clean and ready to use.
Do you store or have access to my documents?
No. Because everything is processed locally in your browser, we have zero access to your files. We cannot see, store or recover any of your documents. You can read the full details in our Privacy Policy.
Does it work on mobile devices?
Yes. PDFinsert works on desktop, tablet and mobile browsers. No app installation is required.
Which browsers are supported?
PDFinsert works best on modern browsers such as Chrome, Firefox, Edge and Safari. We recommend keeping your browser updated for the best experience.
Is there a limit on file size?
File size limits depend mainly on your device and browser memory. Most everyday PDF files work perfectly. Very large files may take longer or require a device with more available memory.
Can I use PDFinsert for commercial purposes?
Yes. You can use all tools for both personal and commercial projects at no cost and with no restrictions.
How is PDFinsert different from other free PDF tools?
Most popular free PDF services upload your files to their servers, often have daily limits, add watermarks, or require an account. PDFinsert processes everything locally in your browser, is completely free with no limits, never adds watermarks, and requires no registration.
