How much smaller will the JPG be?

Photos and screenshots typically shrink by 50–80% compared with the same image as a PNG.

Will I see a quality difference?

At normal viewing sizes, no — the encoder uses a high quality setting. Fine text and sharp line art are the exception; keep those as PNG.

What happens to transparent backgrounds?

JPG has no transparency, so transparent areas are flattened onto white during conversion.

Are my images uploaded?

No. The conversion runs entirely in your browser.

How to Convert PNG to JPG (Free, Smaller Files)

How to convert PNG to JPG

PNG stores every pixel losslessly, which is why a simple screenshot can weigh several megabytes and get rejected by an upload form that a visually identical JPG would sail through.

Converting PNG to JPG is usually the single fastest way to shrink an image without touching its dimensions. Here's how to do it free in your browser, and how to know when you shouldn't.

Convert in your browser

The image is redrawn and re-encoded on your own device — no upload, no queue, no watermark.

1Open the free PNG to JPG converter.
2Drag in your PNG, or click to browse for it.
3The tool re-encodes it as a JPG instantly.
4Download the smaller file — typically 50–80% lighter.

When JPG is the right choice — and when it isn't

Convert photos, screenshots of pages or apps, and anything destined for email, forms or chat: JPG's compression is invisible at normal viewing sizes and universally supported.

Keep the PNG when the image has transparency (JPG flattens it onto white), or when it's crisp line art, a logo or text-heavy UI that must stay pixel-perfect — JPG can soften hard edges.

Need a specific file size instead?

If a form demands “under 1 MB” rather than just “JPG”, use the Image Compressor's target-size mode after (or instead of) converting — it finds the highest quality that fits under your exact limit.
