WebP to JPG
90% looks identical to the original for most photos. Lower means smaller files.
JPG has no transparency, so see-through pixels are filled with this colour.
How to use the WebP to JPG
- Choose WebP files, or drag and drop them onto the box. You can add more at any time.
- Each file converts straight away. Adjust the JPG quality or the background colour and every file is converted again with the new settings.
- Download files one by one, or use Download all.
Examples
- A product photo saved from a website as .webp that an older app, printer or upload form won’t accept. Convert it to JPG at 90% quality and it opens anywhere.
- A logo with a transparent background. JPG can’t store transparency, so pick the background colour of the page or document it will sit on, and the transparent areas are filled with it.
- A folder of WebP screenshots for a report. Drop them all at once, then use Download all.
WebP vs JPG
WebP is an image format created by Google. It usually makes files 25 to 35% smaller than JPG at similar quality, which is why many websites now serve images as WebP. JPG (or JPEG) dates from 1992 and is supported by virtually every device, app, printer and upload form.
When to convert
- An app, website form or older device doesn’t accept WebP.
- You want to edit an image in software without WebP support.
- You are sending images to someone and want them to open everywhere.
If your images are only for your own modern website, keeping WebP is usually better, because the files are smaller.
Quality and file size
JPG is a lossy format: the quality setting trades detail for file size. Around 90% is visually identical to the original for most photos. At 70 to 80% files are much smaller, with slight softening visible on close inspection. The converted JPG is often larger than the WebP, because WebP compresses more efficiently. That is expected and does not mean quality was added. Converting cannot restore detail that the WebP compression already removed.
Privacy
The conversion uses your browser’s own image decoder and canvas. Your files are read and converted on your device, and no image data is sent to CHARTOVANA or anyone else. Converted files exist only in your browser’s memory until you download them or leave the page.
Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens in your browser, so the images never leave your device. You can check this by converting a file with your internet connection switched off after the page has loaded.
Is there a limit on file size or number of files?
There is no limit set by CHARTOVANA. Files are converted one at a time to keep memory use steady. Very large images, roughly above 16,000 pixels on a side or 250 megapixels, can exceed what some browsers can draw. iPhones and iPads have lower limits than computers.
What happens to transparent areas?
JPG doesn’t support transparency, so transparent pixels are filled with the background colour you choose. The default is white. If you need to keep transparency, convert to PNG instead.
Can I convert animated WebP files?
JPG can only hold a single image, so an animated WebP is converted to a JPG of its first frame. The file list marks animated files so this doesn’t catch you out.
Is image metadata kept?
No. Metadata such as camera details and GPS location is not copied into the JPG. That is often a privacy benefit when sharing images.
Why was my file rejected?
The tool reads the start of each file to check that it really is a WebP image, whatever its name. A PNG or JPG that was renamed to .webp is caught and explained, and a WebP saved with the wrong extension still converts.
