Why convert WebP to PNG instead of JPG
WebP to JPG loses transparency and introduces lossy compression artifacts. WebP to PNG preserves transparency and produces a lossless file. If your WebP image has a transparent background, converting to PNG is the only way to keep it.
PNG is also the better choice when you plan to edit the image further. Each time you save a JPG, it recompresses and loses quality. PNG saves are lossless. Convert to PNG for editing, convert to JPG for sharing where file size matters.
How the free WebP to PNG conversion works
The conversion uses the Canvas API in your browser. Your WebP image is loaded into a canvas element with transparency support enabled. The canvas renders the image at its original dimensions and exports it as a lossless PNG file.
If the original WebP has a transparent background, the transparency is preserved in the PNG output. If the WebP is a standard image with no transparency, the PNG output has a solid background matching the original.
The entire process runs in JavaScript on your device. No data leaves your browser. No server processes your file.
What happens to animated WebP files
WebP supports animation, similar to GIF. The Canvas API conversion captures the first frame of an animated WebP and exports it as a static PNG image. The animation is not preserved.
If you need to preserve animation, keep the original WebP file or convert to GIF using a different tool. OnlyFiles does not currently support animated format conversions.
Common questions about free WebP to PNG conversion
Does the PNG preserve WebP transparency?
Yes. If your WebP image has a transparent background, the transparency carries over to the PNG output. PNG supports full alpha transparency.
Why is the PNG file larger than my WebP?
WebP uses more efficient compression than PNG for both lossy and lossless modes. The same image will almost always be larger as a PNG. This is the tradeoff for universal compatibility and lossless quality.
Can I batch convert multiple WebP files to PNG?
Yes. Drop multiple WebP files onto the converter. Each one converts individually in your browser.
