FAQ
Answers to frequently asked questions about signing your PDF, how the signature tool actually works, and the legal side of it.
Sign my PDF
Can I sign a PDF without an account?
Yes. You don't need to create an account to use the current signing tool.
You can use the signing tool directly, without registering or logging in, so there's no username or password to keep track of.
Creating a signature
Can I upload my signature as a PNG or JPG?
Yes, you can choose a suitable image of your signature and place it on the PDF.
In the signing tool, choose the option to add your signature as an image. A PNG with a transparent background usually gives the cleanest result; a JPG may have a white background. Place the image where you want it, resize it, and check the result before downloading.
Can I draw my signature with my mouse or finger?
Yes. You can draw your signature with your mouse, your finger (on a touchscreen) or a stylus.
In the signing tool, choose 'Draw' as the method. You draw directly in the signature box with mouse, finger or stylus, and can clear and start over before placing it.
Can I place more than one signature on a single PDF?
Yes. You can add multiple signatures, even on different pages, and move or remove each one independently.
The editor tracks every placed signature as its own element with its own page, position and size. There's no limit on the number of signatures in the code. Each element has its own remove button, so you can add or remove signatures independently of each other.
How do I move my signature on the PDF?
Just drag the signature with your mouse or finger to the position you want on the page.
A placed signature can be dragged immediately by clicking/tapping and moving it. This works via pointer events, which support both mouse and touch input.
How do I make my signature bigger or smaller?
There's a handle on the edge of the placed signature you can drag to resize it, while keeping its proportions.
Every placed signature has its own resize handle. Dragging it adjusts the width and height while preserving the original aspect ratio, so it doesn't distort.
Can I also add text, like my name, address or a date, to the PDF?
Yes. Besides a signature, you can now also add free text, for example your name, address or a date.
Next to ‘Add signature’, the signing tool also has an ‘Add text’ button. It adds free text (up to 30 characters at a time, with no fixed format) that you can drag and resize just like a signature, using the same resize handle. You can add as much text as you need; the button then changes to ‘Add another text’.
Can I also add my own image, like a stamp or logo, to my PDF?
Yes. Besides a signature and text, you can also upload and place your own image (PNG or JPG, up to 10 MB).
Using the ‘Add image’ button, you upload your own image, for example a stamp, logo or scanned initials. The image appears at a normal starting size on the page and can then be dragged and resized just like a signature, using the same resize handle.
Troubleshooting
Does signing a PDF also work on a phone?
Yes, the tool is built to work on a phone too.
The whole interface is responsive, and the interactions (drawing, dragging, resizing) work through pointer events, which support both mouse and touch input without separate per-device code. This hasn't been physically tested on a real device as part of this review.
Can I sign a password-protected PDF?
No, a password-protected PDF can't currently be signed.
If you try to open a password-protected PDF, the tool explicitly detects this and shows an error that password protection isn't supported yet in this version. Remove the protection first before signing.
What's the maximum file size for a PDF?
A PDF can be up to 50 MB, and an image up to 20 MB.
These limits are actively enforced by the tool itself: files larger than 50 MB (PDF) or 20 MB (image) are rejected with a clear error message.
Legal information
What's the difference between a digital and an electronic signature?
In practice the terms are often used interchangeably, but 'digital signature' strictly refers to the technical method (e.g. based on a digital certificate), while 'electronic signature' is the broader legal term for any non-paper way of giving consent.
An electronic signature is any digital means of recording consent – from a typed name to a drawn signature image. A digital signature is a specific technical implementation of that, usually based on cryptography/certificates, and falls under the heavier categories (advanced/qualified) in the eIDAS regulation. The signature you create with this tool is a simple electronic signature: no certificate, but legally valid for most everyday documents.
Is this a qualified electronic signature?
No. This tool creates a simple electronic signature, not a qualified electronic signature.
A qualified electronic signature requires a certificate from a recognised trust service provider and verified identity checks – this tool doesn't offer that. A simple electronic signature is sufficient for most everyday documents (internal agreements, simple contracts). For documents that legally require a qualified signature (for example certain notarial or official deeds), this tool isn't suitable.
