How to convert WebP to JPG (and when not to)
Updated
Saving an image from the web increasingly gives you a .webp file, and then something refuses it — an upload form, an older photo editor, a printing service, a government portal. WebP is a genuinely better format, but support outside browsers is still patchy.
Converting to JPG solves the compatibility problem immediately. It is worth understanding what you give up, though, because the conversion is not free: WebP is smaller at the same quality, so the JPG you get back will usually be a larger file.
Step by step
Check whether you actually need to convert
Every current browser displays WebP. If the image is for a website, keep it as WebP — it is smaller and looks the same. Convert only when a specific piece of software or a form rejects it.
Choose JPG or PNG deliberately
JPG for photographs. PNG if the image has transparency or sharp text edges, because JPG has no alpha channel and will fill transparent areas with a solid colour.
Convert and check the file size
Expect the JPG to be larger than the WebP was — often 25 to 35 percent larger at comparable quality. That is the cost of the older format, not a mistake.
Compress afterwards if there is a size limit
If the destination caps file size, run the converted JPG through an image compressor rather than converting again.
Things worth knowing
- Converting WebP to JPG then back to WebP loses quality twice. Always work from the original.
- Animated WebP converts to a single still frame — JPG cannot hold animation.
- Transparency is lost when converting to JPG. Use PNG if you need to keep it.
- WebP is supported by every browser released in the last several years; the gaps are in desktop software and older upload systems.
