Which app takes over PDF Expert’s text edits on a Mac?

If what you used PDF Expert for was fixing words in finished PDFs, and the edits came out in the wrong font or the price no longer fits, PDF Textfix does that one job on a Mac. It changes the text already on a page, a line at a time, in the font inside the document, and checks every edit before applying it. It is a one-time purchase: US$29.99 in the Mac App Store or US$29 from this website, with every 1.x update included and no account. Free to try. Your first 5 line edits save clean. After that, saved files carry a watermark until you buy once.

It does not do the rest of what PDF Expert does: annotating, forms, page management, the iPhone and iPad apps. The comparison of PDF Textfix and PDF Expert puts the two products’ facts side by side.

Why do people look for a PDF Expert alternative?

Two things Readdle’s own help and pricing pages describe: how the font of an edit depends on the fonts on your Mac, and the price model.

The font can change when you edit. Readdle’s troubleshooting page says that if fonts “change to another font while editing, this might be because the font is not supported by the system and thus by our app.” Its fix on a Mac is to find the missing font, download it, add it in Font Book and restart PDF Expert. When a document uses a font that is not installed on your Mac, and you cannot or may not install it, a correction can come out in a substitute typeface. The page on editors that keep the original font sets PDF Expert’s rule beside other editors’ rules, each in its vendor’s words.

The price model. Readdle’s pricing page lists US$4.99 a week or US$79.99 a year, each covering Mac, iPhone and iPad, and a Lifetime plan at US$139.99 for the Mac version only. About that plan, the page says: “Get continuous support and bug fixes. Additional new features may come at an extra cost.” Readdle’s billing FAQ also says that to use the app, “you need to register a personalized account”.

Neither is a flaw for everyone. If you annotate and sign on an iPad every day, a subscription that covers it may be exactly right. If you fix a date in a PDF a few times a year, it is a lot to keep paying for.

What does PDF Textfix take over, and how?

Correcting the words that are already on the page.

  1. Open the PDF with File > Open… (⌘O), or drag it onto the app.
  2. Find the line by scrolling, with Find (⌘F), or in the Lines pane.
  3. Double-click it, or select it and press Return. The editor opens on that line, typing in the line’s own font where it can draw it.
  4. Type the change and press Return. The app first checks that every other character on the page stays where it was. The rest of the line stays where it is unless the new text would run into it. Then the app moves the rest of that line, says so in the bar, and Keep Following Text in Place puts it back. Shift Rest of Line (⌃⌘R) moves it by hand. If a check fails, the edit is refused with the reason and the file is left as it was.
  5. Save with ⌘S, or ⇧⌘S to keep the original. The status bar confirms “Saved and verified.”
The demo cover letter in PDF Textfix with the writer's name corrected to Renée Okafor in its heading. Every letter is in the cover letter's embedded serif font except the é, which the embedded font lacks; it is drawn in another font and marked in orange.
The corrected name keeps the cover letter's own embedded font; the one character it lacks is drawn by a fallback and marked in orange.

The font question is where it differs. PDF Textfix does not need the font installed: it draws the new text with the glyphs embedded in the file. When the embedded font lacks a character, it searches in a fixed order:

You type é. The line’s own font has no é.

  1. Another copy of the same font in the file.
  2. The same font, installed on your Mac.
  3. The closest standard font.
Where a missing character comes from. When the line’s own font lacks a character you type, PDF Textfix looks in three places, in this order, and marks the character so you can see it.

First a glyph already in the same font, then another copy of the same face in the document, then the same font installed on your Mac, then the closest standard font. Every character a fallback supplied is marked as you type, in orange, underlined or, when no font can draw it, red. You see the substitution before you apply it, rather than discovering it in the saved file.

Where do PDF Expert’s other jobs go?

Before you cancel, decide where each of them goes:

What else can you use on a Mac instead of PDF Expert?

If you want another general editor, each of these has a page that sets its vendor’s own words beside PDF Textfix, with the source and date of every statement: UPDF, PDFelement, PDFgear, Acrobat, Foxit and Nitro PDF Pro. The side-by-side table of Mac editors puts them on one page with PDF Expert and Preview, and the roundup of free PDF editors for Mac covers the options that cost nothing. None of these pages ranks them.

How do the prices compare?

On October 12, 2026, Readdle listed PDF Expert at US$4.99 a week, US$79.99 a year, or US$139.99 once for the Mac version. PDF Textfix is US$29.99 in the Mac App Store or US$29 from this website (€32 in the EU, €19.99 in Romania, £25 in the UK), paid once. A licence from this website is active on 3 Macs at a time, and activating a fourth removes the one used least recently; the Mac App Store purchase follows your Apple Account. The pricing page has the details, and the page on PDF editors without a subscription lines up the other one-time options.

What happens to your files?

Nothing needs moving. Readdle’s FAQ says that on the Mac, the files you work on in PDF Expert are saved on your Mac, and PDF Textfix opens PDFs wherever they are. Annotations PDF Expert added stay in the file: PDF Textfix leaves comments and form fields as they are, and their text is locked in its editor. A signed PDF needs a decision, because saving an edit means its signatures no longer verify; PDF Textfix asks before your first edit of one.

Is PDF Textfix the right move for you?

  • You mostly correct words in finished PDFs: yes, that is the whole of what it does.
  • Your corrections came out in a substitute font: yes, it writes with the fonts inside the file and marks any character it had to borrow.
  • You annotate, fill forms or work on an iPad daily: keep PDF Expert or another full editor for that, and use PDF Textfix for text fixes if they need to keep the font.
  • Your Mac is an Intel Mac, or runs a macOS version before 26: no, PDF Textfix needs Apple silicon and macOS 26 or later.

The 5 free line edits are enough to check the result on a copy of your own document before you decide.
