The options, honestly compared
Every one of these is free. They fail in different places, which is what should decide your choice.
- 1A browser-based editor — open a web page, drop the file in, edit text, sign, annotate and download. Nothing to install, works on any operating system including phones. Best for everyday edits; not a pre-press or interactive-form authoring tool.
- 2Microsoft Word — opens a PDF by converting it to a Word document, which you then edit and re-export. Fine for text-led documents; complex layouts come back rearranged, and you need Word.
- 3macOS Preview — already installed on every Mac. Good at signatures, annotation, page rotation and reordering. It will not let you change the existing text.
- 4LibreOffice Draw — free and installable on Windows, macOS and Linux, and it does edit existing text. Layout fidelity on complex documents is unreliable, and it is a large download for a five-minute job.
- 5Google Docs — can open a PDF, but strips most of the formatting on the way in. Usable when you only want the words back, not the document.
Which to pick for the job in front of you
Fixing a typo, a date or a figure: a browser editor. It is the only option in this list that changes the words while keeping the page exactly as it was.
Signing or filling in a form: a browser editor, or Preview if you are on a Mac and only need a signature.
Rewriting a document substantially: convert to Word, do the work in a word processor, and export a fresh PDF. Editing dozens of paragraphs inside a PDF is the wrong tool for the job.
Annotating for review: any of them, though a browser editor gives the widest set of markup tools without an install.
What you genuinely give up without Acrobat
It is worth being straight about this rather than pretending the paid tools sell nothing. Acrobat does several things no free browser editor matches: authoring interactive AcroForm fields with validation, certificate-based digital signatures, verified redaction workflows, pre-press colour management and preflight, PDF/A archival conversion, and batch processing across large document sets.
If your work depends on those, the subscription is doing something for you. If — like most people — you need to correct a document, sign it, fill it in or mark it up, none of that capability is involved and there is no reason to pay for it.
The privacy difference worth noticing
Most free online PDF editors upload your document to their servers, process it there and delete it after some retention period you have to take on trust. That is a meaningful disclosure for a contract or a medical letter.
A browser-based editor that runs the work locally avoids the question entirely: the file is read from your disk, edited in memory and written back out, so nothing is transmitted and there is nothing stored to trust anyone about.
