PNG to WebP Converter
Convert PNG images to WebP online for free. This exact converter is built for web-focused image delivery where smaller files and faster page loads matter.
Converting PNG to WEBP re-encodes the image into the WEBP container while preserving resolution and color information. The trade-off depends on the target format: lossy targets (JPG, WebP) shrink file size; lossless targets (PNG, TIFF) preserve every pixel exactly.

What to expect when converting PNG to WEBP
A 5 MB PNG typically becomes 1.5 – 2.5 MB as WebP (lossless mode) or 300 – 700 KB (lossy).
Quality: WebP supports both lossless and lossy. Lossless WebP is smaller than PNG with identical pixels. Lossy WebP is smaller still with minimal visible difference at quality 80+.
Best for: modern web — every modern browser (Chrome, Firefox, Safari, Edge) supports WebP natively.
Avoid when: you need a file that opens in older software (pre-2020 Photoshop, very old Windows), or where universal compatibility matters more than file size.
Tip: For web pages, WebP saves bandwidth without sacrificing visual quality. For email or downloads, stick with PNG/JPG for compatibility.
Switch PNG Images to WEBP in 3 Steps
Change image format for better compatibility, smaller files, transparency support, or a more web-friendly delivery format.
Drag and drop your PNG files or click to browse. Supports photos, screenshots, graphics, and images with transparency. Batch upload multiple files for bulk conversion.
Our engine converts your PNG to WEBP while preserving the original resolution and DPI. Alpha transparency and embedded colour profiles (sRGB, Adobe RGB) are retained where the target format supports them.
Download your converted WEBP images individually or as a ZIP archive. Image quality is maintained at the original resolution — no downscaling or watermarks applied.
Why Convert PNG to WEBP
WebP produces files that are 25-35% smaller than equivalent JPG images at the same visual quality. Switching to WebP can save gigabytes of bandwidth for image-heavy websites.
Unlike JPG, WebP supports alpha transparency like PNG and frame-based animation like GIF — all in a single format. One file type handles photos, graphics, and short animations.
Google developed WebP specifically for web performance. Smaller image files mean faster page loads, improved Core Web Vitals scores, and better search engine rankings for your website.
WebP offers both lossy compression for photos and lossless compression for graphics, letting you choose the right balance between file size and quality for each individual image.
Chrome, Firefox, Safari, Edge, and all modern mobile browsers now support WebP natively. Over 97% of web users can view WebP images without any compatibility issues.

About the PNG Format
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It uses DEFLATE lossless compression, meaning every pixel is preserved exactly as intended — no visual information is discarded during encoding. PNG was developed by the web community and standardized by the W3C and ISO, making it one of the most trusted and universally supported image formats available.
PNG is best suited for screenshots, graphics, logos, and any image that requires transparency. Its support for a full alpha channel allows smooth, semi-transparent edges that blend seamlessly with any background. The main trade-off is file size — PNG files are significantly larger than JPEG for photographic content because no visual data is discarded. PNG does not natively support animation; for animated sequences, APNG (Animated Portable Network Graphics) serves as its extension.
