How to use
Convert PNG images to JPG with a background colour. Choose your file or enter the requested content, select options, then run the tool and download the result.
What happens to transparent pixels?
JPEG does not support transparency. When a PNG with transparent areas is converted to JPG, those pixels must be replaced by a solid background colour. Check the background option before exporting, especially when the image contains a logo, icon or cut-out subject.
When JPG is a good choice
- Photographs intended for broad compatibility.
- Images where a compact file is more important than transparency.
- Uploads to services that specifically require JPEG files.
PNG may remain the better choice for diagrams, interface screenshots, logos and graphics with sharp edges or transparent backgrounds. Compare the converted output before replacing the original.
Privacy and limitations
Processing happens locally in your browser. The page loads standard analytics and, for PDF tools, a third-party PDF library. Some advanced document features may not survive conversion. Check outputs before relying on them.
Frequently asked questions
Are my files uploaded?
No. File processing runs in your browser; the selected file is not sent to a Tolvix processing server.
Will all features be preserved?
Not always. Browser-based conversion may not preserve every annotation, form, font or advanced document feature.
