Why are PNG screenshots so heavy — and how does changing them to JPG help?

When you press the screenshot button on a Mac or Windows computer, the system saves it as a PNG image. PNG is great for logos and graphics with see-through backgrounds, but for a regular picture of your screen, all that extra data just makes the image way bigger than it needs to be. That's often why your email bounces back — the attachments are simply too heavy to send.

The fix is simple: change your PNG to JPG. The JPG format is designed for everyday pictures and photos. It drops the unnecessary see-through-background data and can shrink the image by up to 80% — without making it look blurry. Got a bulk load of PNG screenshots piling up? Drop them all in at once and we'll convert every one, packaging the JPGs into a single ZIP download. And because our free online image converter is safe and runs entirely inside your browser, your private screenshots, work documents, and personal photos are never sent to any server. Nobody else sees your pictures. Ever. It's completely free with no limits, no watermarks, and no sign-up required.

Frequently Asked Questions

What happens to the transparent background when I convert PNG to JPG?

JPG doesn't support transparency, so any see-through areas in your PNG will become solid white in the JPG. If you need to keep a transparent background, consider converting to WebP instead — it supports transparency and is much lighter than PNG.

Will this ruin my original PNG image?

No — we simply create a brand-new JPG copy. Your original PNG picture stays completely safe and untouched on your computer.

I don't know what PNG or JPG means. Can I still use this?

Absolutely! You don't need to understand any technical details. Just pick the picture your boss or coworker asked you to change, drop it here, and we'll handle everything. It's really that easy.

Why does my boss or coworker want a JPG instead of a PNG?

JPG files are much smaller than PNGs, which makes them easier to email, upload to forms, and use in documents. Many systems and portals only accept JPG. If someone asked you for a JPG, it's probably because the PNG was too large for their needs.

Which is better for email attachments — PNG or JPG?

For photos and screenshots, JPG is almost always the better choice for email — the files are typically 5–10x smaller than PNG. This means faster sending, no bounced emails from size limits, and quicker downloads for the person receiving them.
