WEBP to PNG Converter
A free online WEBP to PNG converter that works directly in your browser without uploading files to a server. Convert any number of WEBP images to lossless PNG in a single click, preserve full transparency, keep the original pixel dimensions, and download the result instantly. No registration, no watermarks, no software to install — your photos and graphics never leave your device, which makes the tool safe for sensitive design assets, product mockups and screenshots that you cannot afford to expose online.
How to use
- 1
Add your WEBP files
Drag and drop one or many WEBP images into the upload area, or click to pick them from disk. Everything stays on your device.
- 2
Wait for the conversion
The converter decodes each file with the browser engine and re-encodes it as PNG. Large batches show a progress bar.
- 3
Download your PNGs
Save each file individually, or download the whole batch as a ZIP archive. Original filenames are preserved.
Technical details
WEBP is a modern image format developed by Google that supports both lossy and lossless compression with an alpha channel. PNG is a universally supported lossless format used everywhere — from email signatures and Word documents to social networks, presentations and printable mockups. Converting WEBP to PNG removes compatibility risks for environments where WEBP is not yet accepted.
Under the hood the converter decodes each WEBP file with the native browser image decoder, paints the bitmap onto an offscreen HTMLCanvasElement of the same dimensions, and exports the canvas as a PNG byte stream using the standard `canvas.toBlob("image/png")` API. PNG uses the DEFLATE algorithm: it is mathematically lossless, so every pixel — including those with partial transparency — is preserved bit by bit.
Because the conversion is lossless on the PNG side, the output is typically larger than the WEBP source: PNG cannot reach the same compression ratio. If file size matters more than perfect fidelity, consider the PNG to JPG tool for opaque photos, or our image compression tool to keep PNG output small without altering pixel data structure.
Browser support for WEBP is now universal in Chromium, Firefox and Safari, but legacy CMS plugins, photo printing services, courtroom evidence systems and some PDF generators still expect PNG or JPG. Converting once and storing both formats is a pragmatic compatibility strategy.
