Convert PNG to WebP online free. Transparency preserved. Files up to 70% smaller. Ideal for logos, icons, and web performance. No upload needed.
WebP supports both lossless and lossy compression as well as the transparency (alpha channel) that PNG provides — making it a direct upgrade. WebP-lossless files are 26% smaller than PNG, while WebP-lossy files can be 70% smaller, all while preserving transparent backgrounds.
Convert PNG to WebP for logos, icons, product images with transparent backgrounds, and UI assets that need to be served on the web. This is one of the highest-impact optimizations for website performance.
Unlike JPG, WebP fully supports alpha channel transparency. This means converting PNG logos, icons, and illustrations to WebP gives you the best of both worlds: the transparency of PNG with the compression efficiency of modern web formats. Google specifically recommends WebP for all web images.
Drag your PNG into ImgSwift or click to browse. Transparency is automatically detected and preserved.
Select WebP format. Your transparent background is preserved in the output.
Save your smaller, web-ready WebP file immediately.
Yes. WebP fully supports transparency (alpha channel). Your transparent backgrounds, semi-transparent elements, and logos will be perfectly preserved after conversion.
In lossless mode, no — quality is identical to PNG while being ~26% smaller. In lossy mode at 85% quality, the visual result is excellent and files can be 50–70% smaller than the original PNG.
Yes, highly recommended. WebP logos load faster, support transparency, and reduce bandwidth. This directly improves your site's Google PageSpeed score. All modern browsers support WebP logos natively.
For logos and flat graphics: 90–100% for near-lossless quality. For photos saved as PNG: 75–85% gives excellent results at much smaller sizes.
