Common questions
Step-by-step instructions
Choose the PDF and sign in the box with your mouse, finger or a stylus. You can also upload a photo or image of your signature (JPG or PNG). Pick the page, drag the signature where you want it and adjust its size. If the signature is a photo on white paper, the tool removes the background so it looks clean.
When to use it
Use it to sign a permission form, a quote or a registration form someone sends you as a PDF, without printing and scanning it. Photograph your signature in good light, on white paper, with a dark pen.
Before you start
Draw your signature or load a JPG or PNG. Choose the page and adjust its position and size in the preview. Check which type of signature the recipient requires first.
Are my PDFs uploaded anywhere?
No. PDFs are processed on your device. We do not receive or store your files or their names. The server receives normal requests to load the website and may log connection data, such as your IP address. This version has no analytics, advertising or trackers.
Is it free? Is there a daily limit?
Yes. There is no daily limit, per-document quota or paid plan. Run successive batches as needed. Safety limits are 150 MB per file, 500 pages for rendering and 25 million pixels per page. Available memory may impose lower limits.
Does it work on a phone?
Yes, in modern browsers. A computer often has more memory for large documents. Keep the tab open during processing and check the PDF before sending it.
Can I use this for a procedure requiring a certificate?
No. It adds an image of your signature, not a certificate-based digital signature. Check the recipient’s requirements and use the procedure’s own system if a certificate is required.
How do I position the signature?
Choose the page, draw your signature or load a JPG or PNG, then drag it to the right position. Adjust its size and inspect the downloaded PDF before sending it.
