Questions
Can the watermark be removed?
It is drawn into the page content, so it cannot simply be switched off. Anyone with a PDF editor can still edit page content, as with any watermark.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
