No. You can sign as a guest. Creating a free account raises your limits, and Pro removes ads and lifts the quotas further.
PNG and JPEG. A transparent PNG gives the cleanest result because it sits over text without a white box behind it — see how to make a transparent signature PNG.

Your files are processed in memory to carry out the operation and are not written to disk or retained on our servers afterwards. We don't view, share, or sell them. The one exception is the optional, Pro-only "Chat with your PDF" feature, which sends your document to an AI provider only with your per-session consent. Details are in the Privacy Policy, and the reasoning is in signing without uploading.
The same in-memory handling applies to every document. As with any online service, use your own judgement for highly sensitive material, and read our Privacy Policy so you know exactly how data is handled.
Yes — the core signing, splitting and merging tools are free to use, with daily limits. Guests and free accounts see ads; Pro is ad-free.
There's a daily number of operations, a maximum file size, and a cap on how many files you can process in one bulk run. The exact figures depend on your plan (guest, free, or Pro) and are shown in the app and on your account page. In bulk and split, each input PDF counts as one operation toward your daily quota.
Pro removes ads, raises the daily quota and file-size limits, allows much larger batches, and unlocks the optional "Chat with your PDF" AI feature.
An image of your signature is a form of electronic signature and is accepted for many ordinary business documents, but it carries less legal weight than a certified digital signature if a document is challenged. For high-stakes or regulated documents, a digital signature (DSC) or a government eSign may be required. See electronic signatures in India and electronic vs digital signatures. This is general information, not legal advice.
An electronic signature is any electronic mark showing intent to sign — like a stamped image of your signature. A digital signature is a specific cryptographic method that also proves identity and that the document wasn't altered. The full explanation is in this guide.
