Convert a WebP image to PNG instantly, right in your browser.
Upload a WEBP file to convert it to PNG.
This tool converts a WebP image to PNG entirely in your browser -- the file is decoded, redrawn onto a canvas, and re-encoded as PNG without ever being uploaded to a server. WebP is Google's modern image format, supporting both lossy and lossless compression plus full alpha transparency in a single format -- it typically produces files 25-35% smaller than an equivalent-quality JPEG or PNG. Browser support is now near-universal, though a handful of older tools, some email clients, and some legacy CMS uploaders still expect JPG/PNG specifically.
Click the upload area and choose a WebP file. The converted preview appears immediately; click Download to save it as a real .png file.

Converting to PNG is the right move when you need a real transparent background, or lossless quality for text, logos, and sharp-edged graphics. PNG uses lossless compression -- no image data is discarded, so text, sharp edges, and flat colors (logos, screenshots, diagrams) stay perfectly crisp. It also supports a full alpha (transparency) channel. The tradeoff is file size: a lossless encode of a photograph is typically much larger than the equivalent JPEG.
A WebP file can be lossy or lossless and can carry transparency, and the browser decodes it into a plain grid of pixels before the tool touches it. That means the tool never needs to know which WebP flavor you started with; it only sees the decoded pixels.
PNG output is lossless and keeps transparency, so nothing is thrown away at the save step. The trade-off is file size, which for photographic content can end up larger than the source.
The image is drawn onto a canvas at its natural pixel size and nothing is scaled, so a WebP that measures a given width and height in pixels produces a PNG with the same width and height. Everything runs locally in your browser tab, which is why large files take longer on slower devices.
Imagine a 512 by 512 WebP sticker with a transparent background that an editor will not open. Converting to PNG keeps the transparent area, so you can place it over other artwork afterwards. The PNG will usually be larger, and that is expected.
After the preview appears, a small badge under it shows the pixel dimensions and the source size next to the output size in bytes. Use it as a quick sanity check: if the dimensions are not what you expected, the source file is the cause, not the conversion. This suits logos, screenshots, and graphics that need a transparent background or crisp edges.
Open the downloaded PNG in the program where you will actually use it. Previews in a browser tab can differ slightly from how a print shop, editor, or upload form treats the same file, so a ten second test upload is cheaper than discovering a problem after publishing.
This converter changes the container and encoding, not the picture itself. It does not sharpen, resize, recolor, or remove metadata deliberately, and it cannot recover detail that the source format already lost. Treat the original WebP as your master copy and keep it safe, since converting back and forth between lossy formats only ever makes quality worse.
No -- the whole conversion happens locally in your browser using the Canvas API. Your file never leaves your device.
There's no artificial limit in the tool itself, but very large images take longer to process since everything runs in your browser rather than on a server.
Yes. The image is drawn at its natural pixel size with no scaling, so the width and height carry over unchanged. Use an image editor first if you need a different size.
There is no quality slider in this tool. The file is encoded by your browser with its default settings, and the size badge shows the resulting file size so you can judge it for yourself.
Yes where the source has it. The transparent pixels are drawn onto an empty canvas and the PNG format can store them, so the background stays transparent.
Different formats compress differently. Moving a lossy file to a lossless one, or a well-compressed file to a lightly compressed one, can increase the size. Compare the two byte counts in the badge and pick the format that fits your goal.
Converting WebP to PNG changes more than the file extension -- WebP is best suited to web images that should load fast, both photos and graphics, while PNG is built for logos, screenshots, diagrams and anything that needs sharp edges or transparency.
