PNG to JPG Converter

Portable Network Graphics (PNG) is a lossless image format used for screenshots, logos, transparency and sharp graphics. Files saved as PNG usually come from PNG Development Group / W3C. Before converting, check that the source is the highest-quality copy you have, because every later step can only preserve what is already there.

The target is JPEG Interchange Format (JPG), a lossy image format chosen for photos. You are moving from a lossless source to a lossy encoder, which usually cuts the file size sharply but permanently discards fine detail. The output keeps the original dimensions or sample rate unless you change them, so this step changes the encoding rather than the content.

JPEG output is baseline DCT with a quality setting, and any transparency is composited onto white. It is the safest format for upload forms and email. The source can carry an alpha channel but {toExt} cannot, so transparency is flattened onto a solid background during encoding. Expect a smaller output file, which is usually the reason to pick JPG.

This conversion runs locally in your browser tab through Canvas or FFmpeg.wasm. The file is read from your device, decoded, re-encoded and handed back as a download; it is not uploaded to a conversion server. That keeps private recordings, client material and unreleased artwork off shared infrastructure.

After the download, play or open the result before deleting the original. Check the first and last seconds, confirm that transparency, rotation metadata or sample rate survived, and compare file sizes. If something looks wrong, retry with a higher quality setting rather than converting the output again.
