PNG vs WEBP — What's the Difference?

PNG is lossless but produces larger file sizes. WebP can compress the same image to 30–50% smaller while still supporting full transparency. For websites, WebP is the ideal choice because it combines PNG's transparency support with dramatically smaller file sizes.

Converting PNG to WebP is especially beneficial for website logos, UI graphics, and product images with transparent backgrounds. Google recommends WebP as the next-generation image format for web performance optimization.

Frequently Asked Questions

Is PNG to WEBP conversion free?

Yes — completely free, with no sign-up, no watermarks, and no file count limits. Convert as many images as you need.

Does converting lose quality?

Converting from a lossy format (JPG) to a lossless one (PNG) won't recover lost data, but won't degrade it further. Converting PNG→JPG will apply minimal compression at high quality (90%) so results look identical to the eye. Converting to WebP is also done at high quality (92%).

Are my images stored after conversion?

No. All uploaded files are processed securely and deleted immediately after conversion. We never store your images on our servers.

What happens to transparency when converting to JPG?

JPG does not support transparency. Any transparent areas in your PNG or WebP file will be replaced with a white background in the converted JPG. If you need to preserve transparency, convert to PNG or WebP instead.

Is there a file size limit for conversion?

Fimusk supports image files up to 10MB for conversion. For larger images, consider compressing them first with our Image Compressor before converting formats.
