How to choose a free PDF editor: what to check before you install

FreeUpdated 30 October 20268 min read
The quick answer

Choose a free PDF editor by checking what "free" covers (business use, account, page or file limits, marks on the output, time limits), where your file is processed, which platforms it runs on, and whether it does the tasks you need: text editing, OCR, redaction, forms and export. The best free PDF editor is the one that passes all of those checks for your own files. PDFluent Editor is free for everyone, including commercial use, and needs no account.

Free for everyone, including at work. No account.

You are about to install a PDF editor. Maybe you need to fix a date in a contract, fill in a form, or black out a name before you send a file on. The download button is right there. This page is the list of things to check before you click it.

Free can mean many things, and a PDF editor can do its work in very different places. A few questions, asked up front, save you from finding out halfway through a job that the tool cannot do it, or that it costs money after all.

The checks below work for any editor. For each one, this page also says what PDFluent Editor 1.1 does, so you can compare. PDFluent Editor is free for everyone, including at work, and is available for macOS and Windows.

What "free" can mean: questions to ask any editor

The word free on a download page does not tell you much on its own. Read the terms, or try the editor with a real file, and get an answer to each of these questions.

  • May I use it at work? Some free licences cover personal use only. If you edit files for your job or your company, check that commercial use is allowed.
  • Do I need an account? Ask whether you can open and save a file without signing up, and whether an account is required later to keep using it.
  • Is there a page or file limit? Check whether there is a maximum number of pages, files, or tasks per day or per month.
  • Does it add anything to my file? Look at the saved output for a mark, a logo or a line of text you did not put there.
  • Is it free for good, or for a while? Check whether the free version stops after a trial period.
  • Which features are free? Find out whether the task you need, such as OCR or redaction, is part of the free version or sits behind a paid plan.
What PDFluent Editor does

PDFluent Editor is free for everyone, including commercial and business use. You do not need an account to download it, open a file or save it.

Where your file is processed

A PDF editor either works on the file on your own computer, or sends the file to a website that does the work and sends a result back. For a menu or a flyer that may not matter. For a contract, a payslip or a medical letter, it usually does.

The question to ask is simple: when I open, edit or convert a file, does it leave my computer? If the answer is yes, find out where it goes and how long it stays there. If the editor works without an internet connection, that is a good sign the work happens locally, but check what the editor itself says.

PDFluent Editor on macOS processes documents on your computer, and it works without an internet connection. Opening, editing, converting, redacting and OCR happen on your Mac. The file you work on does not have to go to a website first.

Which computers it runs on

Check that the editor runs on the computers you actually use. If you work on a Mac at home and a Windows PC at work, a tool for only one of them means learning two editors. Also check whether it is a program you install or a page in a browser, since that often decides where the file goes.

PDFluent Editor 1.1 is a desktop program for macOS and Windows. The statement above about processing files on your computer and working offline is made for the macOS version.

Try it on your own computer

PDFluent Editor is free for everyone, including commercial use, and your documents stay on your computer.

Checklist: does it do what you need

Write down the jobs you need the editor for most. Then check each one against the table. The right column shows what PDFluent Editor 1.1 can do.

If you need toCheck that the editor canPDFluent Editor
Fix textChange existing text on the page, not only add a box on top of itYes. Double-click a line or paragraph and rewrite it. Pick a font from the fonts installed on your computer, plus size and colour. The new text must be the same length or shorter.
Change picturesMove, replace or delete a picture that is already on a pageYes
Review and commentHighlight, underline, strike through, add notes, and change or delete them laterYes, plus freehand drawing and attaching a file
Fill in formsFill form fields, run calculations, and handle older XFA formsYes. Calculations work once you allow them, and scripts ask first. Older XFA forms can be filled and saved, and the values are in the file when you reopen it.
Work with scansRun OCR so a scanned page becomes searchable and copyableYes. OCR is built in, with nothing to download, in six languages: English, Dutch, German, French, Spanish and Italian.
Remove private informationRedact so the text is removed from the file, not just coveredYes, by area. On macOS from version 1.1.1 also by search term. Once applied and saved, the text is gone from the file.
Sort out pagesMerge, split, extract, rotate, delete, reorder and insert pagesYes, and compress a large file
Lock or unlock a fileSet a password and remove oneYes. A protected PDF asks for its password when you open it.
Mark a documentAdd a watermarkYes, a text watermark
Convert or exportSave to Word or PowerPoint, images, PDF/A, Markdown or ExcelWord, PowerPoint, PNG, JPEG and PDF/A. Markdown export (Preview) and table export to Excel (Preview).
Handle several filesOpen more than one PDF at a timeYes, each PDF in its own tab

In PDFluent Editor, most of these sit in one place. Click "All tools" in the top bar and the panel lists them by group, for example "Organize pages", "Split PDF" and "Merge files" for pages, and "Redact", "Protect", "Watermark" and "Export / convert" for content and security. Text editing is under "Edit", and conversion has its own tab, "Convert", next to "Sign".

  1. See everything the editor offers in one place

    Open any PDF and click "All tools" in the top bar. The panel on the left groups the tools, so you can check the list against your own needs before you start a real job.

Who PDFluent Editor fits and who it does not

It fits people who work on PDFs one at a time on a Mac or a Windows PC: fixing a line of text, filling in a form, redacting a name, merging a few files, turning a scan into searchable text. It also fits anyone who needs to do that at work without buying a licence, since it is free for everyone, including businesses.

It is a less good fit in these cases:

  • You want to process PDFs automatically, in batches, or from your own code. The editor is made for working by hand. For programmatic processing there is the PDFluent SDK, which is licensed separately.
  • You want to rewrite long passages. Text editing replaces text in place, and the new text must be the same length as the old text or shorter.
  • You need an image watermark. The watermark is text only.
  • You rely on Markdown export or table export to Excel. Both are marked Preview.
  • You need on-device processing and offline use on Windows. This page makes that statement for macOS only.

Test any editor in 10 minutes with your own PDF

A feature list tells you what an editor claims. A short test with a file you actually use tells you whether it works for you. Keep a copy of the original first.

  • Open a real PDF you work with, not a sample. Check that it opens and looks right.
  • Do the one job you need most: change a line of text, fill a form field, or redact a word.
  • Save, close the file and open it again. Check that the change is still there.
  • Check the saved file for marks or text you did not add.
  • If you redacted something, search the saved file for the removed word. It should not be found.
  • If you work with scans, run OCR on one page and try to select and copy a sentence.
  • Note whether the editor asked you to sign in, upload the file, or pay at any point.

If the editor passes these steps with your own file, it is a good choice for you. If it fails one, you found out in 10 minutes instead of in the middle of a deadline.

Frequently asked questions

Is PDFluent Editor really free for business use?

Yes. PDFluent Editor is free for everyone, including commercial and business use.

Do I need an account?

No. You can download PDFluent Editor, open a PDF and save it without creating an account.

Which is the best free PDF editor?

It depends on what you need it for. Check whether commercial use is allowed, whether an account is required, whether there are page or file limits, marks on the output or a time limit, where your file is processed, which platforms it runs on, and whether it can do your tasks, such as text editing, OCR, redaction, forms and export. The editor that passes those checks with your own files is the best one for you.

Free PDF editor for Mac vs Windows: what is the difference?

Check that the editor runs on both if you use both. PDFluent Editor 1.1 is available for macOS and Windows. On macOS, documents are processed on your computer and the editor works without an internet connection.

Is a free online PDF editor safe?

It depends on where your file goes. An online editor usually uploads the file to work on it. Before you use one for a private document, find out where the file is processed, who can access it and how long it is kept. If you would rather not upload the file at all, use an editor that works on your own computer.

Can it edit scanned PDFs?

A scan is a picture of a page, so there is no text to edit until you run OCR. PDFluent Editor has OCR built in, with nothing to download, in six languages: English, Dutch, German, French, Spanish and Italian. After OCR the scanned PDF is searchable and you can copy its text.

Can I use it to process many PDFs automatically?

No. PDFluent Editor is made for working on files by hand. Automated, batch or programmatic processing is what the PDFluent SDK is for.
