Pipeline ready: WebP → PNG (any input still accepted)
Asset Melt Studio is a WebP to PNG converter that runs entirely on your device. Decode WebP back to editable PNG when a tool, printer, or teammate cannot open WebP but you still want a lossless-from-here still.
Drop one WebP or a whole folder — the pipeline is already set to PNG using Oxipng (optional imagequant palette). That is the WebP to PNG workflow people search for: convert WebP to PNG without an upload, then resize, crop, or hit a size budget (when the codec allows) before you download.
Input is not locked to WebP: you can still open JPEG, PNG, WebP, AVIF, HEIC, GIF, and more in the same session. The WebP to PNG URL simply pre-selects PNG so webp to png jobs start in one click.

Step 1
You are already on the WebP to PNG converter. Output is pre-selected as PNG. You can still drop mixed formats — the WebP to PNG URL is a starting point, not a file-type lock.
Step 2
Drag WebP images onto the studio, click to choose, or paste. Folder drops queue nested images. Then process — WebP to PNG encoding runs in Web Workers on this device.
Step 3
Use the before/after scrubber until the WebP to PNG result looks right. Adjust quality, crop, or resize, then download one PNG or a ZIP of the batch.
| Topic | WebP | PNG |
|---|---|---|
| Web | WebP belongs here | PNG is usually heavier |
| Editors | Some still fail | PNG just works |
| Alpha | Yes if present | Kept |
| Size budget | Supported on WebP | Supported (palette search) |
| Animation | Possible | Not encoded |
WebP to PNG is an escape hatch. The PNG cannot be sharper than the WebP. It can be opened in more editors.
If the WebP had alpha, PNG keeps it. If it was a photo WebP, the PNG will be large — that is normal.
Prefer going back to the original JPEG/PNG when you have it.
| Source | Before | After | Note |

| Need small compatible | 300 KB WebP | See WebP to JPEG | Opaque photos |
Drop WebP. Oxipng. Reduce palette only for graphics.

Animated WebP: stills pipeline, not a sequence dump.
Editor/printer that rejects WebP.
Need PNG alpha from a transparent WebP.
Skip WebP to PNG for web delivery of photos.
Lossless PNG of decoded WebP pixels. Palette is extra loss. Do not expect a quality upgrade.
Resize first if the PNG does not need full resolution.
For compatibility without huge files, WebP to JPEG may be better for opaque photos.
Keep the WebP as the small web file.
Image processing is 100% client-side in your browser with WebAssembly. Your photos are not uploaded, I cannot see or recover them, and sampled session replay is UI-only and does not include image pixels (media is blocked). The site still sends usage analytics and crash reports — details are on the privacy page. That includes every WebP to PNG job — the converter never needs your files on a server.
Upload compressors send your bitmap to someone else’s API. Asset Melt keeps webp to png on this device. Session replay, if sampled, is UI-only and does not include image pixels.
