Frequently Asked Questions

Are my confidential PDF documents safe?

Yes. Unlike traditional online PDF services that require you to upload private files to their cloud servers, ToolGrid processes the merger right in your browser's memory. No third party ever sees your content.

Can I merge password-protected PDF files?

If a PDF file has encryption or password protection enabled, you must unlock or remove the password first so the browser engine can parse its pages.

Is there any fee or file size limit?

No. ToolGrid is completely free to use, and because processing relies on your device rather than our server hosting limits, there are no artificial size limits.
