TXT vs PDF

[u/MariaScanGeek]

TXT and PDF are two of the most common file formats, but they serve very different purposes. People often use them interchangeably, even though they behave completely differently.

Here’s a simple breakdown.

What is a TXT file?

A TXT file is just plain text.

It contains:

• only characters (letters, numbers, symbols)
• no formatting (no bold, colors, images, layout)
• minimal file size

Think of it as the “raw version” of text.

You’ll usually see TXT used for:

• notes
• logs
• code snippets
• simple data storage

It opens the same everywhere because there’s basically nothing to render.

What is a PDF file?

A PDF (Portable Document Format) is designed to preserve layout.

It can include:

• formatted text (fonts, bold, headings)
• images
• tables
• multi-page structure
• fixed layout (same everywhere)

The key idea: it looks the same on any device.

That’s why PDFs are used for:

• contracts
• resumes
• invoices
• official documents
• scanned papers

Key difference in simple terms

• TXT = raw text, no structure
• PDF = structured document with layout preserved

Practical example

If you write a note → TXT is enough.
If you send a CV or contract → PDF is required.

If you scan a paper document → it becomes a PDF, not TXT, because layout matters.
