If you’re sitting at your computer trying to finish a PDF right now, you don’t need a complicated workflow. You need a clean way to type your information in the right spots and end up with a PDF that looks normal when you submit it. This page shows you exactly how to do that — whether your PDF is fillable, non-fillable, or a scanned form.

The reason people get stuck

Most people assume every “form PDF” is fillable. It’s not. Some PDFs have real form fields you can click intos. Others are flat pages with boxes printed on them. And scanned PDFs are basically images. So the question isn’t “How do I fill out a PDF?” The real question is: What kind of PDF is it?

Step 1: figure out what kind of PDF you have

1) Fillable PDF (best case)

You can click into boxes and your cursor appears. Typing stays inside a field. These are true forms.

2) Non-fillable PDF (most common)

It looks like a form, but you can’t click into the boxes. The “fields” are printed on the page.

3) Scanned PDF (image-based)

Looks like a photo of paper. Scans don’t contain fields. You typically need to type on top of the image.

Step 2: choose the method that actually works on a computer

Here’s the truth: the “right method” depends on the PDF type. Below is the fastest way to get a clean finished file without messing around for an hour.

BEST OVERALL

Use a “type anywhere” filler and export the final PDF

This is the cleanest approach because it works on scanned PDFs and non-fillable PDFs too. You place your text exactly where it belongs and download a stable PDF for submission.

OK FOR FILLABLE PDFS

Use your PDF viewer to type in fields

If your PDF has real form fields, your browser or PDF reader may let you click and type normally. This doesn’t help much for scans or non-fillable PDFs.

SLOW / LAST RESORT

Print and scan

This is the “fine, I’ll do it the hard way” method. It works, but quality drops and it wastes time.

Step-by-step: fill out the PDF and end up with a file you can submit

  1. Download the PDF to your computer (don’t try to edit it inside an email attachment preview). Save it first so you don’t lose progress.
  2. Open it and try clicking inside a field. If nothing happens, it’s likely non-fillable or scanned.
  3. If it’s not fillable, use a “type anywhere” tool to place text on top of the PDF. This is the fastest route to a clean result.
  4. Download/export the finished PDF. The finished file should look identical everywhere.
  5. Submit it (email, upload portal, print, etc.). Now you’re done. No weird shifting or redoing it.
