Frequently Asked Questions
Is there a file size limit?
You can upload PDFs up to 100MB. That covers most contracts and forms, and since processing happens locally in your browser, even large files stay quick.
Are my documents uploaded to a server?
No. Every file stays in your browser and is never sent to a server. Your document is processed locally and automatically cleared from memory when you finish.
Can I use PDFit on my phone?
Yes. The sign tool works on any phone, tablet or desktop browser, so you can sign documents on the go without installing an app.
Is signing free?
Completely. You do not need an account, there is no watermark, and you can sign as many PDFs as you like for free.
Will signing change the quality of my PDF?
No. The original text, images and layout are preserved exactly, and only your signature is added on top of the page.
What signature types can I use?
You can draw a signature with your mouse, type your name in a cursive font, or upload an existing signature image in PNG or JPG format.
Can I place the signature on any page?
Yes. Use the page navigation arrows to move between pages, then drag your signature into place on whichever page you need.
Are signatures made with this tool legally valid?
In most regions an electronic signature placed this way carries the same weight as a handwritten one for everyday documents. For notarized or court documents, check the specific requirements of your jurisdiction.
Can I add more than one signature?
Yes. You can create and place multiple signatures or initials across the document. Simply repeat the process for each signature you need to add.
Can I change the signature size?
Absolutely. Use the signature size slider to shrink or enlarge your signature before you apply it, so it always fits the space you have.
