How to Convert PNG to JPG
- Add your PNG files - Drag and drop or click to select. Batch convert multiple files at once.
- Set quality - Higher quality means larger files. 90% is a great balance for most uses.
- Choose background color - PNG transparency will be replaced with this color (default white).
- Convert & Download - Click convert, then download each file individually.
The Usual Suspect: A Photo Trapped in a PNG
Most files that arrive at this page are photographs that ended up as PNG by accident: a screenshot of a picture, an export from an app that defaults to PNG, or an edit saved with "keep quality" instincts. The result is a photo carrying several times the bytes it needs. Here is a typical phone-screenshot photo through this tool:
The saving is this dramatic only for photographic content. Flat graphics and text screenshots shrink far less and can even look worse as JPG, which is why the question is not "is JPG smaller" but "is this image a photo".
What the Background Color Actually Does
PNG can hold transparency; JPG cannot. During conversion, every fully or partially transparent pixel gets composited onto the background color you pick, exactly as if the image were laid on paper of that color. For product photos headed to a listing site, white is the standard. For a logo destined for a dark page, converting to JPG at all is usually the mistake; keep it PNG or the edges will carry a visible halo of the flattening color.
Frequently Asked Questions
Why is my PNG photo so huge to begin with?
Because PNG stores photos the wrong way for what they are. Its lossless compression was designed for graphics with flat colors and sharp edges; aimed at the noisy detail of a photograph, it finds little to compress and the file balloons. The same picture encoded as JPG, a format built for photos, is routinely 5 to 10 times smaller.
Will I lose quality converting to JPG?
A little, by design: JPG discards detail the eye is least sensitive to. At the default 90 percent quality the difference is invisible for photos at normal viewing sizes. Text-heavy screenshots are the exception, since JPG can leave faint fuzz around sharp letters; those are often better left as PNG.
What happens to transparent areas?
JPG has no concept of transparency, so transparent regions must become a color, and the background picker controls which one. White suits most documents and listings; match the destination page's background if the image will sit on a colored site.
Can I convert a whole folder of PNGs?
Select or drop as many as you like and each converts in sequence with its own download button. Every file is processed independently, so one unusual PNG cannot stall the batch.
What happens to my images after converting?
Nothing, because they never traveled anywhere. Each PNG is drawn onto a canvas in your browser and re-encoded to JPG on the spot; disconnect from the internet after the page loads and the tool keeps working, which is the plainest proof of where the work happens.
When should I keep PNG instead?
Screenshots of text or interfaces, logos, diagrams, and anything needing transparency. PNG exists for exactly those images, and converting them buys little size while costing edge sharpness. This tool earns its keep on photographs that ended up in the wrong container.
