PNG ↔ JPG Converter
Drop a PNG or a JPG — the tool detects which way to convert and handles transparency properly.
PNG and JPG solve different problems: PNG is lossless and supports transparency, which makes it right for logos, screenshots and graphics; JPG compresses photos into far smaller files but can't do transparency. Converting between them is one of the most common image chores there is — a form that only accepts JPG, a design tool that wants PNG, an email attachment that's 8 MB as PNG and 400 KB as JPG.
This converter keeps it simple: drop a file and it detects the direction automatically — PNG in, JPG out; JPG in, PNG out. When converting PNG to JPG, transparent areas must become a solid color (JPG has no transparency), and you get to choose which one instead of being stuck with white. A quality slider controls JPG output size, with live before/after sizes and a preview. Everything runs locally in your browser, so nothing is uploaded. Converting to or from WebP instead? Use the WebP converter.
How to use the PNG ↔ JPG Converter
- Drop a PNG or JPG file onto the tool — the conversion direction is detected from the file type.
- For PNG → JPG: pick the background color used where the PNG was transparent, and set the JPG quality.
- Check the preview and the before/after file sizes.
- Click Download.
Frequently asked questions
What happens to transparency when converting PNG to JPG?
JPG doesn't support transparency, so transparent pixels must be filled with a solid color. This tool lets you pick that color — white by default, but you can match your page background so the result blends in.
Does JPG to PNG conversion improve quality?
No — converting to PNG can't restore detail the JPG compression already discarded. It gives you a lossless copy of the JPG as it is now, useful when a tool requires PNG input or before heavy editing (so repeated saves add no further loss).
Why is my PNG so much bigger than the same image as JPG?
PNG stores photos losslessly, which is expensive for camera images with millions of subtly varying pixels. JPG is designed exactly for those, at a fraction of the size. Use PNG for graphics with sharp edges and flat colors, JPG (or WebP) for photos.
What JPG quality setting should I use?
90% (the default) is visually indistinguishable from the source for most images. Drop to 75–85% for web use if file size matters; the preview and size readout update live so you can judge.
Are my images uploaded?
No — the conversion runs entirely in your browser with the Canvas API. Files never leave your device, and there are no size limits or watermarks.
