Why convert PNG to WEBP?
Every modern browser supports WEBP, and it routinely produces noticeably smaller files than PNG at equivalent visual quality — including keeping transparency. Swapping PNG assets for WEBP is one of the most common, lowest-effort steps in page-speed optimization.
Supported formats
This page defaults to PNG in, WEBP out, but the tool itself opens PNG, JPG/JPEG, WEBP, GIF, BMP, AVIF, SVG, HEIC/HEIF, or PDF, and can convert to PNG, JPG, WEBP, ICO, or PDF — change the output format in the Convert tab any time.
Frequently asked questions
Does WEBP keep the transparent background?
Yes — WEBP supports an alpha channel the same way PNG does, so transparency carries over exactly.
Is there any downside to using WEBP over PNG?
Mainly compatibility with very old software — modern browsers, operating systems, and design tools all support it fine at this point. For anything web-facing, WEBP is generally the better default.
Are my images uploaded to a server?
No. Every conversion and edit happens locally in your browser using the Canvas API and JavaScript. Files never leave your device.
