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.

Important: what happens to transparent areas

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.

When to convert PNG to JPG vs keep as PNG

Convert to JPG when

  • The image is a photograph
  • No transparent background is needed
  • You want a smaller file for sharing or uploading
  • Maximum compatibility with all devices is needed

Keep as PNG when

  • The image has a transparent background
  • The image contains sharp text or line art
  • You plan to edit it again
  • It is a logo, icon or UI element

How much smaller will my files get?

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.

Frequently asked questions

How much smaller does PNG to JPG make files?

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.

When should I convert PNG to JPG?

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.

What happens to transparent areas when converting PNG to JPG?

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.

Will converting PNG to JPG reduce quality?

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.

Are my files uploaded to a server?

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.

Can I convert multiple PNG files at once?

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.
