Reduce file size for free, no upload required
PNG files are lossless and large. Converting PNG to JPG reduces file size by 60 to 80% for photos with no visible quality loss. Adjust quality, batch convert multiple files and download instantly. Nothing is uploaded.

JPEG does not support transparency. Transparent areas in your PNG will become white.
JPEG does not have a transparency channel. When you convert a PNG with a transparent background to JPG, those transparent pixels become white. This is expected behaviour and the same result you would get in any image editor.
If you have a logo, icon or product photo with a transparent background and need to keep that transparency, convert to WebP instead. WebP supports transparency at file sizes significantly smaller than PNG.

For photographs, PNG to JPG conversion at quality 85 typically reduces file size by 60 to 80%. A 3MB PNG photo often becomes a 500 to 700KB JPG that looks identical on screen. This makes a significant difference for email attachments, website images and storage.
For graphics, screenshots and flat-colour images the savings are smaller. PNG already compresses those types of images efficiently. JPG may sometimes produce visible artefacts around hard edges in flat-colour graphics even at high quality settings.
This converter uses MozJPEG, which produces 10 to 15% smaller files than standard JPEG encoding at the same quality setting. For more on compression and format choices, the image compression guide covers the practical details.
For photographs and complex images, PNG to JPG conversion typically reduces file size by 60 to 80% at quality 85. A 3MB PNG photo often becomes a 500 to 700KB JPG that looks identical on screen. For graphics with flat colours, the savings are smaller because PNG already compresses those well.
Convert PNG to JPG when the image is a photograph and has no transparent background, when you need a smaller file for uploading or sharing, and when you are not going to edit the image again. Keep PNG for images with transparent areas, sharp text, line art, logos and anything you plan to edit further.
JPEG does not support transparency. Transparent pixels in the PNG are filled with white in the output JPG. If you need to preserve transparency, convert to WebP instead, which supports transparent backgrounds at smaller file sizes than PNG.
JPEG is a lossy format so some information is discarded. At the default quality of 85%, the output is visually identical to the original for photographs at normal viewing sizes. You can raise the slider if you need to preserve fine detail, or lower it if file size is the priority.
No. All conversion happens entirely in your browser using WebAssembly. Your PNG files never leave your device. You can verify this by disconnecting from the internet after the page loads, conversion still works.
Yes. Drop multiple PNG files at once or select them from the file picker. Each file converts independently. Download them individually or as a ZIP file.
