What to know before converting PNG to WebP
WebP keeps the same transparent background as PNG while shrinking the file by about 25 to 35 percent on average. With lossy mode, the savings can reach 60 to 80 percent without a visible drop in quality. The benefit grows the more often the image is shown on a webpage, like blog thumbnails and product photos.
WebP isn't always the right call. Tiny 16-pixel icons and flat-color graphics are already small as PNG, so the conversion barely saves anything. Master files for print or design work are safer to keep as PNG so repeated edits don't pile up compression artifacts.
Worried about where the WebP file will display? Modern Chrome, Edge, Firefox, and Safari 14 or later all support WebP natively as of 2026, and messengers like WhatsApp and Discord render it just fine. A few older photo editors still don't open WebP, so keep your originals nearby when you plan to edit later.
