Can mypdf edit text inside an existing PDF like Acrobat?

No, and it is worth being clear about it. You can add text, images, highlights, signatures and page numbers on top of a page, and you can redact content out of it permanently. Rewriting a paragraph that is already in the file — with the original font, kerning and reflow — is something Acrobat does and we do not.

Is the signature from mypdf legally valid?

Sign PDF places an image of your signature on the page. It is not a certificate-based digital signature and carries no cryptographic proof of identity. For visual approval it is usually enough; where a verifiable signature is required, use Acrobat or a dedicated e-signature service.

Do Adobe’s free online PDF tools also work locally?

No. Acrobat’s free web tools upload your document to Adobe servers for processing. The desktop application works locally, but it is the paid product.

Is redaction in mypdf really permanent?

Yes. Applying redaction rasterizes the covered regions into the exported file, so the underlying text is gone from that export rather than hidden behind a black rectangle. Always reopen the download and check every page before sending it.

Adobe Acrobat alternative for everyday PDF work

Adobe invented the PDF format and Acrobat remains the reference implementation. Nothing here claims to replace it.

What Acrobat is, for most people, is an expensive subscription attached to a handful of tasks they do a few times a month: combine some files, shrink one for email, black out an account number, sign a form.

mypdf covers that everyday layer for free, in the browser, without sending the document anywhere — and stops short of claiming the professional layer.

Where Adobe Acrobat is better

Editing the actual text of an existing PDF, with fonts and reflow handled properly. We can add a text layer; we cannot rewrite the original.
Certificate-based digital signatures that a verifier can cryptographically check. Our Sign PDF places an image and is not a legal certificate.
PDF/A conversion, accessibility tagging and compliance checking for archival or regulated work.
Preflight, colour management and print production tools.
Industrial-strength OCR and form recognition.

Where mypdf is different

No subscription and no account for the tasks most people actually perform.
Nothing is uploaded, unlike Acrobat’s free online tools, which process on Adobe servers.
Opens in seconds in a tab rather than needing a multi-hundred-megabyte install.
A privacy scanner that looks for personal data before you share a document.

Which to use

Pick Acrobat if you need true text editing, certificate-based signatures, PDF/A archiving or accessibility tagging. Pick mypdf for the everyday tasks that do not justify a subscription.
