Smaller Files for Faster Pages
WebP is built for the web. Lossless WebP is often smaller than PNG, and lossy WebP can shrink photo-like PNGs much further for faster delivery.
Transparency Stays Intact
Need a transparent background? WebP supports alpha in both lossless and lossy modes, so icons, cutouts, and UI assets keep their transparency after you change png to webp.
Lossless or Lossy Output
Choose the mode that fits the image. Use lossless WebP for pixel-accurate results, or lossy WebP when file size matters more than exact reproduction.
Flexible Download Options
After you convert PNG to WebP, download files one by one, all at once, or as a ZIP archive — whatever matches your workflow.
Why convert PNG to WebP?
Smaller files without giving up transparency
PNG is dependable, but it gets heavy fast on the web. WebP keeps transparency and usually stores the same image more efficiently, which is exactly why png to webp is such a common optimization for product shots, UI assets, and overlays.
A better fit for modern web delivery
Browsers, frameworks, and CDNs all understand WebP well today. If the image is headed to a website, a png to webp converter is often the quickest way to trim bandwidth without reworking the design.
Choose lossless or lossy based on the image
This is where WebP beats PNG on flexibility. You can convert png to webp in lossless mode for screenshots, logos, and sharp interface graphics, or use lossy mode for photo-like PNGs when size matters more than mathematical pixel identity.
Batch-convert large PNG libraries quickly

Private conversion with no upload step
