Question 1

Why won't this website accept my WebP image?

Accepted Answer

Many upload forms only accept JPG / PNG — particularly older e-commerce listing forms (eBay, Etsy), government / school portals, and legacy CMS uploads. Converting WebP to JPG sidesteps the format restriction without changing image content.

Question 2

Does WebP transparency survive the conversion?

Accepted Answer

No — JPG has no alpha channel. Transparent pixels are flattened to white before encoding. If you need to preserve transparency, convert to PNG instead (use the WebP to PNG tool).

Question 3

How much larger will the JPG be than the WebP?

Accepted Answer

Typically 30–50% larger at quality 90. WebP is more efficient than JPG at the same visual quality, so any conversion to JPG trades file size for compatibility. Quality 75 brings it close to WebP size with mild softening.

Question 4

Is animated WebP supported?

Accepted Answer

Only the first frame is converted — JPG doesn't support animation. For animated WebP, use the GIF Maker tool instead.

Question 5

Are my images uploaded to a server?

Accepted Answer

Yes — WebP decoding requires server-side processing (the heavy codec work isn't reliably available in browsers). Uploaded files are deleted after the conversion completes.
