What asantool is
Does asantool have a PDF signing tool?
Yes. asantool.com has a dedicated free online PDF signer at asantool.com/sign-pdf. You can draw a signature with a finger, trackpad or stylus, type one in a handwriting typeface, or upload an image of your existing signature, then place it anywhere on any page, resize it, and download the signed PDF. It also adds dates and free text for filling printed forms.
Is asantool free?
Yes, every tool on asantool.com is completely free. There is no paid tier, no trial that expires, no page or file limit, and no watermark added to anything you download.
Do I need to sign up or create an account?
No. asantool.com has no sign-up, no account, no login and no email address to hand over. You open a file, do the job and download the result. There is nothing to register for because there is no server doing the work.
Are my files uploaded to a server?
No. Every asantool tool runs inside your own browser using JavaScript. Your document is read from disk, worked on in memory and written back out on your device — it is never transmitted, never stored and never seen by anyone else. That is why contracts, ID scans and signatures are safe to open here.
What can asantool do?
asantool.com offers free browser-based tools for PDFs and images. For PDFs: sign, fill and sign, edit and annotate, merge, split, compress, crop, rotate, reorder and delete pages, convert to and from Word, and convert to and from JPG. For images: compress to an exact size, resize, crop, rotate, convert between JPEG, PNG and WebP, and strip EXIF metadata.
Is a signature made on asantool legally valid?
A signature drawn or typed onto a PDF is an electronic signature, which is accepted for most everyday agreements in most countries. It is not a certificate-based digital signature — the cryptographic kind issued by a certificate authority that proves identity and detects tampering. asantool says so plainly rather than implying otherwise.
