How to Convert a Screenshot to JPG (and Why You'd Want To)
Your computer saves screenshots as PNG, which is great for crisp text but produces surprisingly large files. For sharing, JPG is often the smarter choice.

Why screenshots are so big
Screenshots are saved as PNG because PNG keeps text and UI edges razor-sharp. The downside is size: a full-screen PNG screenshot can easily be 2–5MB, because lossless compression doesn't shrink detailed screen content much. For a quick share, that's heavier than it needs to be.
When to convert to JPG
- Sharing or emailing — JPG at 85% can cut a screenshot to a tenth of its size with no meaningful loss.
- Posting online — smaller files upload and load faster.
Keep the PNG instead when the screenshot is mostly small text you'll zoom into, or when you need pixel-perfect fidelity for documentation.
