As a Windows expert with years of experience optimizing workflows, I frequently help users manage screenshot formats. Windows 10 saves screenshots as PNG by default via Windows + PrtScn, but converting to JPG saves space due to better compression. Here are three reliable methods I've used countless times.
Quick Tip: JPG files are smaller and faster to share online, while PNG preserves transparency and quality.
Microsoft Paint is a built-in powerhouse for quick edits and format changes.
Step 1: Capture your screen with Windows + PrtScn. The screenshot saves to Pictures > Screenshots and copies to the clipboard.
Step 2: Search for and open Paint.

Step 3: Paste with Ctrl + V.

Step 4: Go to File > Save As, select JPEG, choose a location, name the file, and save.



The Snipping Tool lets you capture and save directly in JPG.
Step 1: Search for and open Snipping Tool.

Step 2: Click New, then drag to select your area.

Step 3: Save with Ctrl + S or File > Save As.

Step 4: Choose JPEG from the Save as type dropdown and save.
