Quick Answer
The best free PDF editor for Mac depends on the edit. Apple’s built-in Preview handles signing, forms, page changes and redaction but cannot change existing text. PDFgear and LibreOffice Draw edit existing text at no cost, Skim suits note-taking, and Acrobat Reader and Sejda offer limited free tiers.
Key Takeaways
- Apple’s Preview guide states that you can’t edit the text of a PDF in Preview, although its Markup toolbar includes Text, Sign, Redaction Selection, Crop and Form Fill tools.
- PDFgear is listed as free on the Mac App Store (macOS 12 or later), and its developer says saved PDFs carry no watermark and no account is required.
- LibreOffice is free, open-source software under the Mozilla Public License 2.0, with version 26.8.1 offered for both Apple Silicon and Intel Macs as of October 2026.
- Adobe’s free Acrobat Reader covers viewing, commenting, form filling and signing, while Adobe states that editing text and images requires Acrobat Pro or Acrobat Studio.
- Sejda’s free tier allows 3 tasks per day on the desktop app and 3 tasks per hour online, for documents up to 200 pages or 50 MB.
Which free PDF editors work on a Mac?
There are 6 free PDF editors and readers for Mac worth comparing. They are Preview, PDFgear, LibreOffice Draw, Skim, Adobe Acrobat Reader and Sejda. The first four cost nothing for their full feature set, while Acrobat Reader and Sejda are free tiers of paid products that limit editing or usage.
The distinction matters because “free” on Mac software listings often means a trial or a viewer with editing locked behind a subscription. Readdle’s PDF Expert is an example: Readdle’s support article on how to get PDF Expert says the Mac app can be used for free as a PDF viewer, with editing part of the paid Premium tier. For that reason, PDF Expert is not counted as a free editor in this comparison.
This roundup compares each tool using its vendor’s published features and limits as of October 2026. TechJournal did not run hands-on tests of these apps. For step-by-step instructions on Preview and the two free text editors, see the TechJournal guide on how to edit a PDF on a Mac for free.
How do the free Mac PDF editors compare?
The free Mac PDF editors differ most on 3 points. They are whether the tool can change existing text, whether the free version has usage limits, and whether files leave your Mac. The table below summarizes those points from each vendor’s documentation.
| Tool | Edits existing text | Free-version limits | Where files are processed | Mac requirement (vendor) |
|---|---|---|---|---|
| Preview | No (Apple states text cannot be edited) | None; included with macOS | On the Mac | Built into macOS |
| PDFgear | Yes, according to the developer | None stated; App Store lists no in-app purchases | On the Mac; AI and online features need internet | macOS 12 or later (App Store) |
| LibreOffice Draw | Yes, as editable text objects | None; open source (MPL 2.0) | On the Mac | Apple Silicon and Intel builds |
| Skim | No; notes and highlights only | None; open source (BSD license) | On the Mac | macOS 10.13 or higher |
| Acrobat Reader | No; editing needs Acrobat Pro or Studio | View, comment, fill and sign only | On the Mac | macOS 10.15 or later |
| Sejda (desktop and web) | Yes, except in scanned documents | 3 tasks per day (desktop), 3 per hour (web), 200 pages or 50 MB | Desktop: on the Mac; web: uploaded, deleted after 2 hours | Apple Silicon and Intel |
For most users, the table points to a simple rule. Preview covers everyday paperwork, and one of the free text editors handles the cases where the wording itself must change.
Is Preview good enough as a free PDF editor?
Preview is good enough for most everyday PDF tasks on a Mac, but it is not a full editor. Apple’s guide to annotating a PDF in Preview states that you can’t edit the text of a PDF in Preview and directs users to the Markup tools instead. Those tools include Text, Note, Highlight Selection, Shapes, Sketch, Sign, Redaction Selection, Crop and Form Fill.
The practical benefit is that Preview needs no download, keeps documents on the Mac and handles the tasks most people need: signing a lease, filling a form, merging two files, deleting a page or redacting an account number. The limitation is that anything added with Markup sits on top of the page. A typo in a paragraph, an outdated price in a table or a wrong date in a letterhead cannot be corrected in Preview.
The most sensible approach is to try Preview first and move to a dedicated editor only when the original wording must change. Preview’s redaction tool is also worth knowing for privacy reasons, because a shape drawn over text hides it visually but leaves the underlying text in the file.
Which free Mac PDF editor can change existing text?
PDFgear, LibreOffice Draw and Sejda can change existing text in a PDF on a Mac without payment, each with a different trade-off. PDFgear keeps the layout in place, LibreOffice Draw is open source but can shift complex layouts, and Sejda limits the number of free tasks.
PDFgear
PDFgear is the free Mac editor that most closely resembles a paid PDF suite. The developer’s PDFgear for Mac page describes it as a completely free PDF editor and reader, says saved PDFs do not carry watermarks, and says users can start without registering or signing in. The same page lists text editing without converting to Word, whole-document OCR and electronic signatures. These are the developer’s own claims.
The PDFgear Mac App Store listing shows the app as free, lists no in-app purchases, requires macOS 12 or later and names PDF GEAR TECH PTE. LTD. as the seller. The main caution is connectivity: PDFgear states that AI features and online services require an internet connection, so avoid sending confidential documents to the AI chat feature.
LibreOffice Draw
LibreOffice Draw is the open-source choice for editing PDF text on a Mac. The official LibreOffice download page offers version 26.8.1 for Apple Silicon and Intel Macs and states that the source code is licensed under the Mozilla Public License v2.0. Draw opens a PDF as a set of separate objects, such as text boxes, lines and images, and exports a new PDF through File > Export As > Export as PDF.
The trade-off is layout fidelity. Tables, multi-column pages and uncommon fonts can move or be substituted when the PDF is imported, so LibreOffice Draw works best for short documents and small corrections. Check every page before sharing the result.
Sejda
Sejda edits existing text in a desktop app or in the browser, within free-tier limits. The Sejda Desktop page lists builds for Intel and Apple Silicon Macs and sets the free version at 3 tasks per day, with documents up to 50 MB and 200 pages. Sejda also states that changing existing text within scanned documents is not supported.
The Sejda online PDF editor allows documents up to 200 pages or 50 MB and 3 tasks per hour on the free service, and Sejda says uploaded files are deleted automatically after 2 hours. The online version suits occasional edits on a Mac where installing software is not possible, but any upload sends the file to a third-party server.
Which free PDF tools suit reading and annotating on a Mac?
Skim and Adobe Acrobat Reader suit reading and annotating PDFs on a Mac, but neither changes existing text in its free form.
Skim is a free PDF reader and note-taker designed for reading and annotating scientific papers. The Skim project site lists notes, highlights, snapshots, table-of-contents navigation, a presentation mode and export of notes as text, and requires macOS 10.13 or higher. The project’s SourceForge page lists a BSD license. Skim is a strong fit for students and researchers who annotate long documents, but it is not an editor for changing a document’s content.
Adobe Acrobat Reader is the free version of Adobe’s PDF software. Adobe’s Acrobat Reader page says the free app lets users comment, fill out forms and sign PDFs, and states that advanced tools such as editing text and images require a subscription to Acrobat Pro or Acrobat Studio. The listed Mac requirement is macOS 10.15 (Catalina) and later. Acrobat Reader is useful when a sender expects Adobe-specific form behavior, but Preview already covers most of the same free tasks.
How do you choose the right free PDF editor for your Mac?
To choose the right free PDF editor for your Mac, match the tool to the edit you need and to how sensitive the document is. Follow these steps:
- Open the PDF in Preview first and check whether the Markup toolbar covers the task, such as signing, filling, merging or redacting.
- Install PDFgear from the Mac App Store if existing text must change and the layout should stay the same.
- Download LibreOffice from the official site if you prefer open-source software and the document has a simple layout.
- Install Skim if your main need is highlighting and annotating long reading material.
- Use Sejda’s free desktop app or website only for occasional edits, and keep within its daily or hourly task limits.
- Save every edited file as a new copy so the original remains available.
Download each app from the Mac App Store or the developer’s official website rather than from a search ad or a download aggregator. Counterfeit download pages are one route for Mac malware, as the TechJournal report on the AmnesiaStealer macOS infostealer explains, and no legitimate PDF app asks you to paste commands into Terminal during installation.
Stop and ask the sender for an editable original when the file is a contract, tax form or official record. Changing the text of a signed or official PDF can produce a document the other party never agreed to, and in those cases the correct fix comes from the person who issued the file. If large scanned PDFs make your Mac sluggish, the guide to fixing a slow MacBook covers memory and storage causes, and the broader roundup of the best free PDF editors covers Windows and browser tools.
