How PNG to JPG Conversion Works
PNG (Portable Network Graphics) uses lossless compression and supports alpha-channel transparency. JPG (JPEG) uses lossy compression optimised for photographic content and does not support transparency. Converting PNG to JPG involves re-encoding the image data into JPEG format at your chosen quality level.
Step 1: Flatten PNG transparency → fill with chosen background colourSince JPG has no alpha channel, any transparent pixels must be replaced with a solid colour before encoding. This tool fills transparent areas with your selected background colour (default: white).
Step 2: Encode as JPEG → toDataURL('image/jpeg', quality/100)The Canvas API re-encodes the flattened image as JPEG at the specified quality (0.0–1.0). Lower quality = smaller file with more compression artefacts. Higher quality = larger file with sharper detail.
Size Reduction (%) = ((PNG Size − JPG Size) / PNG Size) × 100Typical PNG-to-JPG conversions produce 40–80% smaller files for photographic content. For flat-colour images like logos, the difference may be smaller.
Practical Conversion Examples
What is a PNG to JPG Converter?
A PNG to JPG converter is a tool that transforms image files from the PNG format into the JPEG format. These two formats serve different purposes: PNG is designed for images that need transparency, sharp edges, or lossless fidelity — such as logos, icons, and screenshots. JPG is designed for photographs and complex visual scenes where some quality loss is acceptable in exchange for significantly smaller file sizes.
Converting PNG to JPG is a common task for website owners, bloggers, online store managers, and digital content creators. A PNG file of a product photo might be 3–5MB. The same image converted to JPG at 85% quality will typically be 300–600KB — a reduction of 80–90% — with no visible difference at normal viewing sizes. This directly impacts page load speed, hosting bandwidth, and storage costs.
This tool handles the conversion entirely in your browser. There is no server involved, no file upload to a third party, and no risk of your images being stored or shared. The HTML5 Canvas API renders your PNG, applies the background fill colour to any transparent areas (since JPG does not support transparency), and encodes the output as a JPEG at your chosen quality level. The result is ready to download in seconds.

Is this PNG to JPG converter free to use?
Yes, this converter is completely free. No account, no payment, and no usage cap.
Does my PNG file get uploaded to a server?
No. The conversion happens entirely inside your browser using the HTML5 Canvas API. Your file never leaves your device.
Why does PNG to JPG conversion reduce file size?
PNG uses lossless compression and supports transparency, which increases file size. JPG uses lossy compression optimised for photographs, producing much smaller files with minimal visible quality loss.
What happens to transparent areas in my PNG?
JPG does not support transparency. Any transparent areas in your PNG will be filled with the background colour you choose in the tool. The default is white.
Will converting PNG to JPG reduce image quality?
At quality settings of 80 and above, most people cannot perceive any visible change. Lower settings will reduce file size further but may introduce slight JPEG artefacts, especially in areas with sharp edges or text.
Can I convert multiple PNG files at once?
Currently the tool converts one PNG at a time. Upload a new file after downloading to convert additional images.
What is the maximum PNG file size supported?
The tool supports PNG files up to 20MB. Very large files may take a few extra seconds depending on your device.
When should I use JPG instead of PNG?
Use JPG for photographs, product images, and any image without text or transparency. Use PNG for logos, screenshots with text, icons, and images requiring transparent backgrounds.
Does the image dimensions change during conversion?
No. The pixel dimensions of your image remain exactly the same. Only the file format and quality encoding change.
Can I use the converted JPG for commercial purposes?
Yes. Format conversion does not affect the licensing or ownership of your image. You retain all rights to your file.
Does this tool work on iPhone and Android?
Yes, the tool is fully responsive and works on modern mobile browsers including Safari on iOS and Chrome on Android.
