When to convert WebP to JPG
Sending images via email
Many email clients display WebP as attachments rather than inline images. Convert to JPG to ensure recipients see your images properly regardless of their email app.
Printing photos from web downloads
Downloaded a WebP image you want to print? Many print services and photo kiosks require JPG. Convert before uploading to your print service.
Opening web images in older software
Older versions of Photoshop, Illustrator, and Office apps can't open WebP. Convert to JPG to work with these images in any software.

How do I convert WebP to JPG on Mac?
Open Picmal, drag your WebP files into the window, select JPG as the output format, adjust quality if needed, and click Convert.
Does converting WebP to JPG lose quality?
There is some quality reduction since JPG uses lossy compression. At 90-95% quality, the difference is invisible to the eye. Files will be larger than the original WebP.
Why can't I open WebP files in some apps?
Despite wide browser support, many desktop applications (older Photoshop versions, Office suite, some email clients) don't support WebP. JPG is the safe choice when you need the image to open everywhere.
Will the file size increase when converting WebP to JPG?
Yes. WebP is 25-35% smaller than JPG at the same quality, so the JPG comes out roughly 40-50% larger. In the examples on this page, a 420KB WebP becomes 620KB as JPG.
Can I batch convert WebP to JPG?
Yes. Drag entire folders of WebP files into Picmal and convert them all to JPG at once.
