Why convert PNG to JPG?
PNG is lossless and large; JPG uses lossy compression that makes photos 5–10× smaller with no visible difference. For photos JPG is almost always the better format; keep PNG for logos, text and graphics with sharp edges or transparency.
Limitations
- Animated images are converted as a single still frame.
- Very large images (over 100 megapixels) are refused to protect your device’s memory.
Privacy
Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.
Frequently asked questions
What happens to transparency?
JPG has no transparency, so transparent pixels are filled with the background colour you choose (white by default).

Open this page in your phone’s or computer’s browser, choose the PNG files and click Convert to JPG. Nothing is installed and nothing is uploaded.
