How it works

Turn a PNG into a much smaller JPEG with a quality slider, entirely in your browser. Nothing gets uploaded.

PNG is lossless, which is why screenshots and exported graphics balloon to several megabytes. Re-encoding as JPEG typically cuts photos and screenshots by 70-90% with little visible difference at quality 80+. One real trade-off to know before you convert: JPEG has no alpha channel, so any transparent areas in your PNG become a solid white background. If you need to keep transparency, convert to WebP instead. The conversion happens on a canvas in your browser — the file never touches a server, so it's safe for private screenshots, IDs, and documents. Adjust the quality slider (40 to 100), watch the output size, and download. The filename keeps the source name with a .jpg extension.

Frequently asked questions

Will my PNG's transparency survive?

No. JPEG doesn't support transparency, so transparent pixels become white. Use PNG to WebP if you need to keep the alpha channel.

How much smaller will the JPG be?

Photos and screenshots typically shrink 70-90%. Flat graphics with few colors shrink less, and text-heavy images may show slight JPEG artefacts around letters.

What quality setting should I use?

80-90 is visually indistinguishable for most images. Drop to 60-70 for thumbnails where a smaller file matters more than fine detail.

Is my PNG uploaded anywhere?

No. The conversion runs on a canvas in your browser. The file never leaves your device.
