What is JPG conversion?

JPEG is the one image format every device, CMS and messenger accepts, and this tool converts PNG, WebP, GIF, HEIC and other formats to JPG right in your browser. Photos from an iPhone arrive as HEIC — great compression, terrible compatibility — and this tool handles them directly, no desktop app required.

Two options shape the output. Quality controls the compression: higher keeps more detail at a larger file size, and for photographs a value around 80 to 90 is usually indistinguishable from the original while noticeably smaller. Background color matters for transparency: JPG has no alpha channel, so transparent areas of a PNG or WebP must be filled in — white is the usual choice, but any color works for dark-mode assets.

You can convert several images at once and download the results together. Conversion uses the browser's own image decoder and canvas, which means your files are processed locally and never uploaded — no waiting on a server queue, and no reason to worry about client photos or private screenshots.

One honest limitation: JPEG compression is lossy. Every conversion re-encodes the image, so repeatedly converting back and forth slowly degrades quality. Keep the original if you plan to edit again later; convert once, at the quality you need, and use the result for sharing.
