Frequently asked questions

Is PDFwerk really free?

Yes. All tools work without an account and without limits. The site is funded by ads.

Are my files uploaded?

No. Processing happens entirely in your browser. Your documents are never sent to a server or stored anywhere.

Does it work on my phone?

Yes, in every current browser on phones, tablets and computers. Very large files are faster on a computer.

How much does compression shrink a PDF?

Scanned documents and image-heavy files often shrink by 50 to 90 %. Pages are re-saved as images, so text can no longer be selected afterwards.

How to sign a PDF

  1. Choose the PDF file.
  2. Type your text or draw your signature with your finger or mouse. You can also upload an image of your signature.
  3. Click the spot in the document where it should appear and save the PDF.

Fill in forms and sign leases, authorisations or consent forms without printing and scanning. Use the watermark to mark copies as “CONFIDENTIAL” or “COPY”.

Frequently asked questions

Is a signature added this way legally valid?

It counts as a simple electronic signature, which is enough for many everyday documents. Where the law requires a handwritten signature on paper, you still need one.

Can I fill in several places?

Yes. Place as many texts and signatures on different pages as you like before saving.

Which characters are supported?

Latin characters including accents and umlauts work. Other scripts such as Cyrillic are not supported yet.
