Convert WebP to JPG
free, instant, private

No. This converter processes your image entirely in your browser using JavaScript and the HTML5 Canvas API. When you select a file, your browser reads it locally using the FileReader API — no network request is made and no data leaves your device. You can verify this by opening your browser's developer tools (F12) and checking the Network tab while converting — you will see zero outbound requests.

JPG is a format that does not support transparency (alpha channel). When a WebP image has transparent areas — such as a logo with a clear background — and is converted to JPG, those transparent pixels must be filled with a solid color. This converter fills them with white, which is the standard behavior and works correctly for most uses. If you need to preserve transparency, convert to PNG instead, which supports an alpha channel. For a different background color, you would need an image editor like Photoshop, GIMP (free), or Canva to fill the transparency before exporting to JPG.

Yes, to a small degree, because both WebP (in lossy mode) and JPG use lossy compression. The conversion process decodes the WebP back to raw pixels and then re-encodes those pixels as JPEG. This second round of compression introduces some additional quality loss. At the default 92% quality setting, this loss is visually imperceptible for most images when viewed on screen. At 95–100% quality, there is essentially no visible difference. At 70% or below, some degradation becomes noticeable, especially in high-contrast edges and text. For images that will be printed professionally, use 95% or higher.

There is no explicit file size limit — the practical limit is your device's available RAM. A 10MP WebP image (around 5–15MB) converts instantly on any modern smartphone or computer. Very large images (50MB+) may take a few seconds and could cause issues on older devices with limited memory. If you experience browser crashes with very large files, try reducing the browser's other open tabs to free up memory, or use a desktop image editor like Photoshop or GIMP for oversized files.

The current version of this converter handles one file at a time. For batch conversion of multiple WebP files, you have several options: on Mac, use the Terminal command for f in *.webp; do sips -s format jpeg "$f" --out "${f%.webp}.jpg"; done. On Windows, tools like IrfanView (free) support batch conversion. In Photoshop, use File → Scripts → Image Processor. A free batch converter option online is Squoosh by Google, which also handles WebP.

This converter works in any modern browser that supports the HTML5 Canvas API and FileReader API, which includes Chrome 10+, Firefox 4+, Safari 6+, Edge 12+, and all modern mobile browsers. Internet Explorer 11 partially supports the required APIs but is no longer a supported browser. Essentially any browser released after 2015 works correctly. The WebP decoding itself is handled by the browser — if your browser can display WebP images (which all modern browsers can), it can also convert them using this tool.

File size depends on the image content and the quality setting you choose, not the original size. A WebP file converted to JPG at 92% quality will typically be 1.5–3× larger than the WebP, because WebP's compression is more efficient than JPEG's. A 200KB WebP might produce a 400–600KB JPG at 92%. At 80% quality, the JPG might be 250–350KB. At 100% quality it could be 1–2MB. The physical pixel dimensions (width × height) of the image are always preserved exactly during conversion.

Yes, completely different. Renaming a file only changes the file extension label — it does not change the actual file format or the data inside the file. A WebP file renamed to .jpg is still a WebP file internally, and will still fail to open in any application that does not support WebP. Proper conversion, as this tool performs, actually re-encodes the pixel data into the JPEG format so the resulting file is a genuine JPEG that opens correctly in any application.

Web developers and Content Delivery Networks use WebP because smaller image files make pages load faster, which improves user experience and search engine rankings. Google's PageSpeed Insights tool explicitly recommends "serving images in next-gen formats" (meaning WebP or AVIF) as a performance optimization. A website serving 50 images per page can reduce total image payload by 30–40% by using WebP instead of JPG, which can significantly improve load times on mobile connections. The tradeoff is that these optimized images are less convenient for end users who want to download and use them outside a web browser.

There is no difference. JPG and JPEG refer to exactly the same image format. The JPEG acronym stands for Joint Photographic Experts Group, the committee that created the standard. Early Windows operating systems limited file extensions to three characters, so the four-character .jpeg extension was shortened to .jpg. Mac OS and Linux systems always used .jpeg. Both extensions are universally recognized by all software today, and a file named photo.jpg and one named photo.jpeg are identical formats.
