Format Details
PNG
PNG (Portable Network Graphics) is a widely-used lossless raster image format created as an open, patent-free alternative to GIF. It supports 24-bit color, full 8-bit alpha channel transparency, and highly efficient lossless compression. PNG is the preferred format for images with sharp edges, text overlays, logos, and any content where pixel-perfect lossless quality is essential, and it is universally supported in every browser and application.
imageWebP
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. It typically produces files 25-34% smaller than JPEG at equivalent quality, and up to 26% smaller than PNG for lossless images. WebP also supports animation and alpha transparency, making it a versatile single replacement for JPEG, PNG, and GIF in modern web applications.
imageConverting PNG to WEBP: what actually changes
PNG to WebP is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .PNG and .WEBP each hold
.PNG is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .WEBP is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .WEBP encodes pixels, dimensions and colour depth — not what the file is about.
Quality and file size
Both .PNG and .WEBP are lossless, so the content itself survives the trip intact. The main difference is how efficiently each format packages pixels, dimensions and colour depth — which is what changes the file size.
When this conversion is the right one
Reach for .WEBP when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .WEBP to .PNG using the same tool.
Tips for a clean PNG to WEBP conversion
Start from the original file
Convert the .PNG you started with, not an earlier .WEBP output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/png becomes image/webp. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .PNG has a transparent background or animation, confirm .WEBP supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
