How WebP to PNG conversion works
This tool reads the selected WebP file, decodes it into pixel data with the browser's Canvas API, then re-encodes those pixels as PNG through the browser's built-in encoder — from file selection to a downloadable PNG file in the same tab, without a server-side upload endpoint for this processing flow. The PNG output is always lossless; the quality slider does not apply.
Because this is browser-native, encoder speed and exact output byte size vary between Chrome, Firefox, Safari, and Edge, though the resulting pixels are visually identical across browsers since PNG has no lossy step.

WebP and PNG compatibility
PNG has some of the widest compatibility of any lossless image format: browsers, image editors, operating systems, and most desktop-publishing and print workflows accept it without exception. WebP is supported in current browsers, but some design tools, older content-management systems, and print pipelines still expect PNG or JPEG instead.
See the WebP vs PNG comparison guide for a size and transparency breakdown. The main converter's image format guide also covers JPEG, GIF, SVG, and BMP.
Quality behavior for WebP to PNG
PNG is a lossless output format, so the quality dropdown does not apply once PNG is selected. Converting a WebP file to PNG cannot recover anything the source already lost: if the WebP was saved with lossy compression, that loss is already permanent, and the PNG output simply repackages those same pixels losslessly from that point onward — typically at a noticeably larger file size than the WebP source.
The practical reason to convert WebP to PNG is compatibility rather than quality: some editing software, older upload forms, and print workflows do not accept WebP. The alpha channel carries over correctly, since PNG supports transparency the same way WebP does.
Batching WebP to PNG conversions
Expect the PNG output to be larger than the source WebP file, sometimes substantially so for photographic images, because PNG's lossless compression is less efficient than WebP's lossy or lossless modes for photo-like content. This affects download and storage size rather than conversion speed: decode memory in the browser depends on pixel dimensions, roughly 48 MB per 12-megapixel image, not on the source or output file size.
For large batches of photographic WebP files, plan for noticeably bigger downloads. Keep batches to about 50 images on desktop and 10 to 20 on mobile, and use the ZIP download for the full set.

Frequently Asked Questions
Is the conversion local?
Yes. The conversion uses browser-native image processing. File contents are not intentionally uploaded by this tool.
Can I convert multiple WebP files at once?
Yes, you can drag and drop hundreds of WebP files and convert them all to PNG in one click.
What is the limit?
There is no account-level file count limit. Practical limits depend on your device memory and browser capability.
Which version should I use for sensitive files?
