Why convert images to WebP
WebP is the format the modern web settled on. It compresses photographs 25 to 35 percent smaller than JPEG at matching visual quality, supports transparency like PNG at a fraction of the weight, and is decoded natively by every current browser: Chrome, Safari, Firefox, Edge, and everything built on them. Converting your JPG and PNG images to WebP is one of the highest leverage page speed improvements available, which is why performance audits keep recommending it.
JPG to WebP and PNG to WebP, batch converted
Drop both formats in together. Photographic JPGs become lossy WebP at your chosen quality, where 80 is the proven sweet spot for the web. PNGs with transparency keep their alpha channel, so logos and UI graphics arrive as transparent WebP files that are often 70 to 90 percent lighter than their PNG originals. Every conversion runs in your browser, in parallel, with a single ZIP download at the end.
When WebP is the wrong choice
A short honest list. Email newsletters: some older email clients still render WebP inconsistently, so JPG remains the safe attachment format. Print workflows: print shops want JPG, PNG, or TIFF. Very old software: a legacy tool that predates the format will not open it. For those cases, convert the other direction with PNG to JPG, or keep originals alongside the WebP versions. For everything destined for a web page, WebP wins. Already have WebP files that are heavier than they should be? The WebP compressor shrinks them without changing format.
