A practical guide

Move a still WebP into a lossless, transparency-friendly workflow.

Converting WebP to PNG can help when a design application, document tool, or upload form does not accept WebP but does accept PNG. The browser decodes the visible WebP pixels and writes a fresh lossless PNG. Transparent pixels can remain transparent because both formats support alpha.

PNG output may be much larger, especially when the WebP contains a photograph or was encoded lossily. Lossless PNG preserves the decoded result; it does not restore color detail already discarded by the WebP source. Animation is not retained by this still-image canvas workflow. Use the conversion for compatibility and editing needs, then compare the actual byte size before distribution.

How to use it

From file to finished in four moves

Choose still WebP images and let PixelShrink decode and validate them locally.
PNG is preselected and uses the browser’s lossless encoder, so no quality choice is needed.
Convert, then inspect transparency, visible detail, and the measured increase or reduction in bytes.
Download the PNG for the workflow that needs it while keeping the WebP original.

Format notes

Know what changes—and what does not.

Transparency can remain transparent

PNG supports alpha, including soft semi-transparent edges, so no solid background is introduced.

Lossless output can be significantly larger

Detailed images often require more bytes as PNG than as lossy WebP. Compatibility may be the benefit, not size.

Decoded quality is the ceiling

PNG stores the pixels produced by the WebP decoder without another lossy step, but it cannot recreate discarded source information.

Good fits

Useful choices for real files.

A design app needs PNG

Create a transparent PNG copy for an editor that cannot import WebP, then continue work from the original when possible.

A document template rejects WebP

Convert a still diagram or logo to PNG for compatibility while keeping crisp edges and alpha.

Privacy by design

Your image does not become our file.

WebP decoding and PNG encoding happen in local browser memory, including transparent pixel data. PixelShrink never receives the selected file or result, and the generated download URL exists only within the page session.

Frequently asked questions

Answers before you start.

Will transparency be preserved?

Yes for still WebP images with alpha. PNG supports transparent and semi-transparent pixels.

Does PNG restore quality from a lossy WebP?

No. It avoids an additional lossy encode, but cannot reconstruct information already removed from the source.

Why did the PNG become much larger?

PNG stores decoded pixels losslessly. Photographic content that was compact as lossy WebP commonly needs more bytes in PNG.
