Why JPG Is Still the Safest Format When You Don't Know Where a Photo Is Going

Newer formats trade universality for efficiency

Formats like WebP and AVIF generally compress better than JPG, but that efficiency came at the cost of being newer, which means decades less time for every piece of software in existence to add support for them. JPG had a multi-decade head start.

Where "almost everywhere" isn't quite enough

When sending a photo to someone whose device, software, or platform you don't control — a print shop, an older relative's computer, a specialized business system, or an unfamiliar upload form — "widely supported" isn't the same guarantee as "supported everywhere." JPG remains the one format with close to universal, multi-decade-proven compatibility.

The trade-off you're accepting

Converting a WebP image to JPG typically increases file size somewhat compared to the WebP original, and JPG doesn't support transparency the way WebP can. For pure photographic content without transparency needs, this trade-off is usually a fair price for guaranteed compatibility.

When to keep WebP instead

If you know the image is only ever going to be viewed in a modern web browser — on your own website, for instance — there's no compatibility reason to give up WebP's smaller file size by converting to JPG.
