PNG vs WEBP: what changes when you convert
PNG (Portable Network Graphics) was introduced in 1996 by the PNG Development Group as a GIF replacement and is best known for logos, screenshots, ui graphics, images that need transparency. WEBP (WebP), created by Google, is the better choice when you need website images — smaller than jpg and png at the same quality.
Why convert? WEBP files are typically much smaller than PNG — expect a noticeable reduction in file size.
Upload one file or a whole batch — conversion happens over a secure HTTPS connection and finished files are automatically deleted from our servers within minutes. Some older apps, email clients, and Windows photo viewers still cannot open WebP files.

Quick answers about this PurePDF workflow.
How do I convert PNG to WEBP?
Upload your PNG files on this page. PurePDF opens the conversion workspace with WEBP preselected — click Convert and collect the finished files from the download hub.
Will converting PNG to WEBP reduce quality?
No. WEBP supports lossless compression, so every pixel of your PNG image is preserved exactly.
Is transparency preserved when converting PNG to WEBP?
Yes. Both PNG and WEBP support alpha transparency, so transparent backgrounds survive the conversion intact.

It depends on the image content, but WEBP typically produces significantly smaller files than PNG. Photographic images see the biggest savings.
Is the PNG to WEBP converter free?

Are my files private?
