Convert PNG to JPG
Drop a PNG and download it as a JPG. The output is usually 5-10x smaller, which is exactly why most people make this conversion. Runs in your browser, nothing uploaded.
About the png to jpg
PNG is lossless, so a photo saved as PNG is needlessly huge. The single most common reason to convert PNG to JPG is file size: a 6MB PNG screenshot of a photo becomes a 400KB JPG with no visible difference. JPG is also accepted everywhere PNG sometimes is not (older upload forms, print labs, some email clients that choke on large attachments). The trade-off: JPG is lossy and has no transparency, so any transparent areas in the PNG become white. If your PNG is a logo, screenshot of text, or anything with sharp edges, keep it PNG. If it is a photo, JPG is the right call. Renza converts locally via the Canvas API with a quality slider, no signup, no watermark.

Tips for best results
Things that meaningfully improve the output.
Transparency turns white
JPG has no alpha channel. Any transparent pixels in the PNG are flattened to white. If you need transparency, stay on PNG.
Quality 85-92 is plenty
For most photos you will not see a difference above quality 85. Higher just means bigger files.
Keep PNG for graphics
Logos, icons, screenshots of text: JPG blurs sharp edges. Only convert photos.

Why is my JPG so much smaller?
PNG is lossless and stores every pixel exactly. JPG uses lossy compression tuned for photos, which is why a photo PNG shrinks 5-10x.
Does the file get uploaded?
No. Conversion runs in your browser. The PNG never leaves your device.
What happens to transparent areas?
They become white. JPG does not support transparency.
Will I lose quality?
JPG is lossy, but at quality 85-92 the loss is imperceptible for photos.
Need it the other way?
Use /tools/jpg-to-png for JPG to PNG.
