What PNG to JPG Converter does
PNG to JPG Converter decodes one verified PNG, paints it onto a solid background, and encodes the canvas as JPEG at the selected quality. This is useful when an app or publishing system accepts JPEG but not PNG.
JPEG has no transparency channel, so transparent and partly transparent PNG pixels must be blended with the chosen background color. Conversion changes the encoding; it does not add detail or improve a low-resolution source.
How to use PNG to JPG Converter
- Select one PNG file no larger than 20 MB.
- Choose the background color for transparent pixels and set the JPEG quality.
- Convert the image, inspect the displayed file size, and download the JPG.
Important details
Transparency becomes a solid color
Every transparent pixel is composited onto the selected background before JPEG encoding. White works for most documents, while a brand or page color can prevent an unwanted white box.
Quality controls compression, not dimensions
The quality slider changes JPEG compression but keeps the decoded pixel dimensions. Lower settings usually create smaller files and may introduce ringing or block artifacts around text and sharp edges.
Practical uses
- Prepare a transparent PNG product image for a catalog that accepts JPEG uploads.
- Reduce the transfer size of a screenshot or graphic when transparency is unnecessary.
- Choose a matching background before inserting a PNG into software with poor alpha support.
Privacy and limitations
The PNG is read and converted locally in the browser; PagesTools does not upload it for this operation.
The tool accepts one PNG up to 20 MB and applies browser canvas safety limits of 12,000 pixels per side and 40 megapixels. JPEG output cannot retain transparency, animation, layers, or PNG-specific metadata.
