If I can Paste small colored pics like this🔥on text files, why can't I paste large colored pics, like jpeg files, on text files?

The short version: a plain text file can only store text characters, not actual image data.
Those little emoji‑style pictures you can paste (🔥, 😀, 🌈) aren’t real images — they’re just Unicode characters. A JPEG is real binary image data, and a .txt file has no way to store or represent that.

🔥 Why emojis work in a text file

Emojis are Unicode characters.
That means they’re just numbers like any other letter:

A → U+0041

🔥 → U+1F525

A text file stores characters as encoded numbers (UTF‑8, UTF‑16, ASCII, etc.).
So emojis fit perfectly because they are text.

🖼️ Why JPEGs don’t work in a text file

A JPEG is binary data — thousands or millions of bytes describing pixel colors, compression tables, metadata, etc.

A .txt file is designed to hold only text, not arbitrary binary. When you try to paste a JPEG:

The OS or editor refuses because the data isn’t text

Or it tries to convert the binary to text and corrupts it

Or it pastes nothing at all

It’s like trying to store a whole photograph inside a dictionary — the format simply doesn’t support it.

📌 But you can embed images in other text‑based formats

Some formats look like text files but actually support binary or encoded data:

HTML → <img src="...">

Markdown → 

Base64‑encoded images → text representation of binary

Rich Text (RTF) → supports embedded images

Word docs (.docx) → zipped XML with media folders

But a .txt file is intentionally simple — no formatting, no images, no metadata.

🧠 The key idea

Emojis = text
JPEGs = binary image data
.txt files = text only

So you can paste emojis, but not actual pictures.

If you want, I can show you how to embed a JPEG inside a text file using Base64, which technically works but isn’t visually displayed — it just stores the image as text.
