Convert Bulk WebP to JPG in Browser
Convert one or many WebP images to compatible JPG files locally in your browser for uploads, documents, and older apps.

What happens to each file during conversion?
Each file is decoded by your browser, drawn onto a white canvas at its original pixel size and saved as a JPG at the quality you set. Partly transparent pixels are blended with the white: pure red at 50 percent opacity comes out as a light red close to RGB 255, 127, 127. JPG has no animation, so an animated WebP becomes a single still frame. The drop zone takes other image types as well, so a PNG or GIF that your browser can open converts the same way.
Conversion and ZIP packing both run in your browser, and the files are not uploaded. Camera details stored in a WebP, such as EXIF data, are not copied into the JPG.
How does the quality setting affect the JPG?
The slider runs from 50 to 100 percent and starts at 92. Each row lists the original size next to the new one, so you can compare after converting. A JPG at 92 or above is often larger than the WebP it came from, because WebP usually compresses photos more tightly. Lower the setting if the new file is too big for the place you are uploading it.
Each press of Convert all to JPG converts every file in the list at the current setting, including files already converted, so you can move the slider and press the button again to redo the whole batch. If a file in the list cannot be decoded, its row shows "Could not convert this image" and the other files still convert. Download ZIP leaves that file out.
How do batch downloads and file names work?
Each converted file gets its own Download button, and Download ZIP packs every converted file into jpg-conversion.zip. Names keep the original base with a .jpg extension, so beach.webp becomes beach.jpg. Two inputs with the same base name, such as logo.webp and logo.png, both become logo.jpg, and the ZIP keeps only one of them, so rename duplicates first. You can drop more files at any time; they join the list and wait for the next Convert all.
For screenshots and logos, especially ones with transparent areas, the WebP to PNG Converter keeps every pixel and the alpha channel. JPG compression leaves faint ripples around sharp edges such as small text, which PNG avoids. The Image to WebP Converter goes the other way.
