Why convert JPG to WebP?
JPG and WebP serve different purposes. Converting between them lets you use whichever format works best for your situation.
What is a JPG file?
Joint Photographic Experts Group: JPEG is the default format for photographs. If you've taken a photo with your phone or downloaded an image from the web, chances are it was a JPEG. It uses lossy compression to keep file sizes small while maintaining reasonable visual quality.
Created by: Joint Photographic Experts Group (ISO/IEC), first published in 1992
Used for: Photographs, web images, email attachments, social media uploads
Technical details: Lossy compression with adjustable quality. Higher quality means bigger files. Does not support transparency. Works best for complex images with lots of color variation like photos.
Compatibility: Universally supported on every device, browser, and platform.
What is a WebP file?
Web Picture format: WebP is Google's image format built specifically for the web. It produces smaller files than both JPEG and PNG while keeping similar quality. Most modern browsers support it, though older software sometimes does not.
Created by: Google, first released in 2010
Used for: Web images, page speed optimization, anywhere file size matters
Technical details: Supports both lossy and lossless compression, plus transparency and animation. Typically 25-35% smaller than JPEG at comparable quality.
Compatibility: All modern browsers (Chrome, Firefox, Safari, Edge). Some older image editors may not open WebP files.
