What PNG to JPG conversion does

Convert a PNG image into JPG for broad device and website compatibility. Processing stays in your browser, and you can tune JPEG quality before download.

JPG does not support transparency. Transparent PNG pixels are flattened onto white so the output stays predictable across browsers.

How to convert PNG to JPG

1. Choose a PNG file.
2. Adjust JPEG quality if needed.
3. Select Convert & download.
4. Save the .jpg file from your browser downloads.

When JPG is preferable

JPG is often a better fit for photographs and everyday sharing where transparency is not required. It does not guarantee a smaller file than PNG in every case.

What happens to transparency

Before JPEG encoding, the canvas is filled with white, then the PNG is drawn on top. Soft edges and partial alpha blend against that white background.

JPEG quality setting

The quality slider defaults to 90%. Lower values usually shrink the file and can introduce compression artifacts.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted images remain on your device.

Limits

• Inputs: PNG only, up to 25.0 MB and 8,192 px per side.
• Files must look like real PNGs (signature check) and decode successfully. Renamed or corrupted files fail safely.
• Metadata is not preserved. Orientation depends on browser decoding via createImageBitmap.

PNG to JPG FAQ

Will JPG be smaller than PNG?

Often for photographs, but not always. Complex graphics, screenshots, or already-small PNGs may not shrink. File size depends on image content and the JPEG quality setting.

What happens to transparent pixels?

JPEG has no alpha channel. Transparent or semi-transparent pixels are flattened onto a white background before encoding.

Does conversion reduce quality?

JPEG is lossy. You can raise or lower the quality slider (default 90%). Higher quality usually means a larger file.

Are images uploaded?

No. PNG to JPG conversion runs locally in your browser and does not upload your image to Looty Tools servers.

Can I choose JPEG quality?

Yes. Use the JPEG quality slider before converting. Values range from 50% to 100%.
