Are my files uploaded to a server?

No. This conversion runs inside your browser using your own device’s processing power, and the file is not uploaded. Once a tool has been used once (video, text recognition and background removal download their engine from this site the first time), it keeps working when your connection drops.

Why will not my WebP files open elsewhere?

WebP is a newer web format that some desktop and mobile applications still do not read. JPG is one of the most widely supported image formats, which is why converting usually fixes it.

Is quality lost in the conversion?

Both formats are lossy, so re-encoding costs a little fidelity. The quality score under the result shows how much.

Convert WebP to JPG

Runs on your device · Your file never leaves your device.

WebP images saved from websites often will not open in older photo editors, office software or on some devices. Convert them to JPG, a far more widely supported format.

Batch conversion handles a folder of saved images in one pass, with an optional size limit for uploads.

The picture is re-encoded as JPG at a high quality setting; any transparent regions become white, since JPG does not support an alpha channel.

Supported formats and limits

Input: WebP images
Output: JPG
Why convert: Older software, printers and some editors still reject WebP
Transparency: Filled with white, as JPG cannot store it
Where it runs: In your browser; nothing uploaded

Not for: Keeping transparency — convert to PNG instead if the image has a transparent background.

Animated and transparent WebP files

A WebP can hold an animation, which is common for stickers and short clips saved from websites. A JPG holds one picture, so the browser draws the first frame and only that frame is converted.

A WebP can also be transparent. Transparent areas become white in the JPG, and half-transparent edges are blended with white. For a sticker or logo whose transparency matters, /webp-to-png keeps it.

Why the JPG is often larger than the WebP

WebP files on websites are usually made to be as small as possible, and JPG cannot store the same picture in as few bytes. A converted file that is bigger than the WebP is therefore normal, not an error; the result card shows both sizes. If the JPG needs to be small, lower the slider or switch on Force a maximum file size.

Some WebP files are lossless, the kind used for screenshots, diagrams and text. Converting one to JPG makes it lossy, and sharp text can soften. /webp-to-png keeps such an image exact.

Which quality setting to choose

A photographic (lossy) WebP always stores colour at half the resolution of brightness. From 90 on the slider the JPG stores colour at full resolution, but for a lossy WebP that only adds bytes, because the extra colour detail was never in the file. The default of 85 suits these pictures.

For a lossless WebP with coloured text or fine coloured lines, 90 or above is worth the extra size, because there the colour detail does exist.

If a WebP will not open here

The picture is decoded by your browser, so a browser too old to display WebP cannot convert it either; current versions of the common browsers can. The browser recognises the picture by its content rather than its name, so a file ending in .webp that is really a JPG or PNG still converts.
