How to convert PNG to WEBP

The PNG is decoded on your device and re-encoded as WEBP with the browser's own graphics engine. Because nothing is uploaded, even dozens of photos convert quickly and privately. WebP is typically 25-35% smaller than JPG at the same quality, which makes websites faster and improves Core Web Vitals.

Step 1: Choose your PNG file
Drag and drop a .png file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Pick the quality (optional)
Keep the recommended setting or adjust it, then the conversion runs instantly.
Step 3: Download the WEBP
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

Transparency is preserved.
WEBP is a lossy format; the quality setting balances file size and sharpness (85-92% is visually lossless for most photos).
Photo metadata (EXIF, GPS location) is removed from the converted image, which is good for privacy.

About the formats

What is PNG?

PNG (Portable Network Graphics) is a lossless image format created in the mid-1990s as an open replacement for GIF. It keeps every pixel exactly as it was and supports an alpha channel, so images can have smooth, partial transparency. Photos saved as PNG are much larger than the same photos as JPG.

Use PNG for logos, icons, screenshots, diagrams and any image with sharp edges, text or a transparent background. For photographs where file size matters, JPG or WebP are usually better choices.

What is WEBP?

WebP is an image format developed by Google and released in 2010 to make web images lighter. It supports both lossy and lossless compression, transparency and animation, so it can replace JPG, PNG and GIF in many cases. All modern browsers display it, although some older desktop programs still cannot open it.

Use WebP for images on websites and apps, where smaller files mean faster pages. If you need to send an image to someone who will edit it or open it in older software, JPG or PNG are the more compatible choice.
