How To Edit Pdf On Mac

Tips
1

I received an important PDF on my Mac that I need to update with text edits, add a few signatures, and maybe insert a page, but I’m not sure which built‑in tools or free apps are best. Preview is confusing and I’m worried about messing up the formatting. Can anyone walk me through the easiest, reliable options to edit PDFs on macOS, preferably without paying for expensive software

Preview is confusing at first, but for what you need it works fine and is safe.

Here is a straight workflow on macOS, all with built in tools or free apps.

  1. Simple text edits in the PDF
    Important detail. If the PDF is not a fillable form, you are not really “editing” text, you are drawing new text on top. That is normal.

    Preview:
    • Open PDF in Preview.
    • Show Markup toolbar: View → Show Markup Toolbar.
    • Click the Text tool (the little “T” in a box).
    • A text box appears. Type your edit.
    • Move it where you want. Adjust font with the “A” button.
    • For redlines, use the underline, strikethrough, or shapes in the toolbar.

    If you need true text editing in the middle of paragraphs, you need a real editor.

    Free options:
    • LibreOffice Draw

    • Install LibreOffice.
    • Open the PDF in Draw.
    • Edit text directly.
    • Export to PDF.
      Works best on simple layouts. Complex PDFs get messy.

    • PDFgear or PDF Expert trial
    Both allow more “real” text editing. Watch for trials and watermarks.

  2. Add signatures without risk
    Preview is fine for this and does not send your signature to Apple.

    Setup once:
    • Open PDF in Preview.
    • Markup toolbar → Sign icon.
    • Create Signature.

    • Use Trackpad or
    • Use Camera and sign on paper.
      • Save it.

    Use it:
    • Click Sign.
    • Pick your signature.
    • Click where you want it. Resize with the corners.
    • If you need date or name, add Text box next to it.

  3. Insert, delete, reorder pages
    Preview again.

    • Open PDF in Preview.
    • Show thumbnails: View → Thumbnails.
    • To insert a page from another PDF:

    • Open both PDFs in Preview.
    • Drag the page thumbnail from source PDF to the target PDF’s sidebar.
      • To insert a blank page:
    • Edit → Insert → Page from File or Blank Page.
      • To delete: select thumbnail, press Delete.
      • To reorder: drag thumbnails up or down.

  4. Save safely without losing original
    This part trips people.

    • Before editing, duplicate the file.

    • In Finder, right click → Duplicate.
    • Or in Preview: File → Duplicate.
      • Work only on the copy.
      • When done: File → Export as PDF.
      This avoids overwriting something you may need later.

  5. If Preview starts to feel too limited
    Here is a simple breakdown of free or freemium tools:

    • PDF Expert free tier

    • Good UI.
    • Great for annotation and signing.
    • Text edit is paywalled.

    • PDFgear

    • Free at the time of this writing.
    • Has text edit, merge, split.
    • Less polished, but works.

    • LibreOffice Draw

    • Open source.
    • Works offline.
    • Better for short, simple PDFs.

  6. What I would do for your case
    You said you need text edits, signatures, and insert a page.

    • Use Preview for:

    • All signatures.
    • Inserting and reordering pages.
    • Light text overlay edits.

    • If you must edit existing text cleanly:

    • Try opening the PDF in LibreOffice Draw first.
    • Fix the text. Export to PDF.
    • Then re open in Preview and handle signatures and pages.

That keeps everything local on your Mac, no upload to random web sites, and you avoid most surprises.

Preview is clunky, but since you’re uncomfortable with it already and this is an important doc, I’d actually split your workflow across a couple tools instead of forcing everything into Preview like @viajeroceleste suggested.

Here’s how I’d tackle your specific combo: text edits + signatures + page insert, without paying and without uploading to some shady website.

1. For “real” text edits (not just text on top)
If the PDF isn’t a simple form and you care how it looks, I would start with:

  • LibreOffice Draw (free, offline)
    • Use it only for structural text edits and layout changes.
    • It’s not pretty, and it can mess up complex PDFs, but it’s still better than fighting Preview if you want to actually change words inside paragraphs.
    • Once done: export back to PDF.

If LibreOffice mangles the formatting too much:

  • PDFgear desktop app
    • Still free last time I checked.
    • Better at keeping layout intact than Draw in a lot of cases.
    • Use it only for text changes, then save and move on.

I personally avoid using Preview for anything more than cover-up corrections, because if spacing and fonts matter, those “overlay text” boxes get ugly quickly.

2. For signatures (where you really don’t want cloud nonsense)
Here I actually agree with @viajeroceleste: Preview is the least annoying option and keeps everything local.

What I’d suggest that’s slightly different:

  • Create two signatures in Preview:
    • One neat full signature
    • One simple initials version
  • Use initials for doc pages that want you to initial every page, and the full signature only where needed. This keeps the pages cleaner and easier to read.

If you have to sign a lot of stuff and Preview feels janky:

  • PDF Expert free tier
    • Very good for just signing and filling fields.
    • Do your text edits first in another app, then final signing in PDF Expert.
    • Avoid paying for the text-edit upgrade if you can handle that part elsewhere.

3. For inserting / rearranging pages
Preview can do it, but if its interface is driving you nuts, alternate route:

  • Use Finder’s Quick Look + PDFgear or PDF Expert
    • Figure out which pages you need by previewing in Quick Look (spacebar in Finder).
    • Then open in PDFgear or PDF Expert and use their page management.
    • Some people find those page thumbnails much clearer than Preview’s sidebar.

Or, if you can tolerate Preview just for page stuff:

  • Do the page insert / reorder in Preview only, nothing else.
  • Don’t touch text tools there at all; treat it like a page organizer.

4. Versioning so you don’t wreck the “important” original
Slightly different approach than what was mentioned:

  • Keep a small naming scheme:
    • document_original.pdf
    • document_edit-text.pdf (after LibreOffice/PDFgear)
    • document_signed-final.pdf (after Preview or PDF Expert)
  • Never sign on the same file you used for text editing. If you discover a typo after signing, you don’t have to redo all signatures from scratch.

5. Simple workflow recipe tailored to you

  1. Make copies in Finder first.
    Duplicate the original and rename it with “_edit-text”.

  2. Open that copy in LibreOffice Draw or PDFgear.
    Do all textual changes there. Save/export to PDF as “_text-done”.

  3. Open “_text-done” in either:

    • Preview, if you can tolerate its page thumbnails
    • Or PDFgear / PDF Expert for page insert/reorder
      Insert the new page, delete what you don’t need, then save as “_pages-done”.

  4. Final step: open “_pages-done” in Preview or PDF Expert and do only signatures.
    Save as “_signed-final”.

This breaks the job into three simple stages with one main tool per stage, instead of trying to master Preview’s entire toolbox in one stressful go. It also keeps everything on your Mac, no forced subscriptions, and you’ll always have the earlier versions to fall back on if something glitches.
