PNG to JPG converter
Drop a PNG and get a JPG back. The conversion runs in this tab on your own machine, so a private screenshot never leaves your device.
JPG has no transparency: see-through pixels are filled with the background colour above, white by default.
How to convert PNG to JPG
Add the PNG
Drop the file on the box above, paste it from the clipboard or pick it from your disk. Several PNGs at once are fine.
Pick the quality
Quality 92 suits photos. Lower it when the file has to be small, raise it to 100 for flat graphics where edges show compression.
Download the JPG
The converted file appears with its new size. Download it, or convert the next PNG without reloading the page.
What changes when PNG becomes JPG
PNG stores pixels losslessly and can carry an alpha channel, which is why screenshots, logos and interface graphics are saved as PNG. JPG stores a lossy approximation and has no alpha channel at all — its strength is photographs, where the discarded detail is detail the eye barely notices, and the result is a fraction of the size.
So a PNG becomes a JPG in three moves: transparent pixels are flattened onto a background colour, the image is encoded with the quality you choose, and the metadata your camera or editor wrote is dropped. Anything already lost by a previous JPG round-trip stays lost, and text or thin lines lose their crispness first — keep the PNG if the image is a screenshot you may edit later.
PNG to JPG questions
Is my file uploaded anywhere?
No. The conversion uses the canvas and encoder built into your browser, so the file is read from your disk, converted in memory and saved back to your disk. There is no server step, which also means the tool works offline once the page has loaded.
Why did my transparent background turn white?
The JPG format has no alpha channel, so transparency has to be resolved before encoding. This converter fills those pixels with the background colour you pick — white by default, or any colour you type. Pick a colour that matches the page or slide the image will sit on.
Which quality setting should I use?
92 is a good default for photos: visually identical to the source in almost every case. Drop to 80–85 when the file must be small, and go to 100 for images with sharp edges or text, where lower settings show ringing around the strokes.
Does converting PNG to JPG reduce the resolution?
No. Pixels are copied one for one unless you set a maximum width or height, which scales the image down proportionally. Nothing is ever upscaled, so a 1200-pixel PNG stays 1200 pixels wide.
