How to Convert WebP to PNG (Lossless)

Yes — converting WebP to PNG is the right move when you need lossless quality or transparency. PNG preserves every pixel exactly. The trade-off is a 3–5× larger file size compared to the original WebP.

Why convert WebP to PNG

WebP is great for the web. PNG is the right format for editing, design, transparency, and any workflow that needs pixel-perfect output:

You need a transparent background (logos, UI assets, design mockups)
You're importing the image into Photoshop, Figma, or Sketch and need lossless quality
You're saving the image as a master file you'll edit or re-export later
You're submitting to a system or client that requires PNG specifically

3 ways to convert WebP to PNG

1. Open in Photoshop, Affinity, or GIMP and Save As PNG

Photoshop 2020+, Affinity Photo, or GIMP (with WebP plugin) can open WebP and save as PNG. Works for individual files, but no real batch mode. Photoshop and Affinity are paid; GIMP is free but the WebP plugin setup on Windows is non-trivial. For a one-off image, fine. For 50 images, painful.

2. Use an online WebP to PNG converter

CloudConvert, Convertio, and similar sites convert WebP uploads to PNG. They work for one-off files but every image uploads to a server. Most cap file size at 25–100 MB, and PNG files are typically 3–5× larger than WebP — so files that fit the cap as WebP may not fit as PNG. Your images sit on a stranger's server during the conversion.

3. Use EasyImg (desktop, local, lossless)

EasyImg is a desktop app for Windows and Mac that converts WebP to PNG entirely on your computer. Drag in a folder of WebP images, pick PNG, click Convert. The output is bit-identical to the decoded WebP pixels — no quality loss, no compression artifacts. A typical WebP converts in about 0.4 seconds; 200 images finish in a couple of minutes. No upload, no queue, no file size cap, no internet required.

WebP to PNG — common questions

The PNG output is lossless — every pixel of the decoded WebP is preserved exactly. Note that if the source WebP was lossy (the default WebP mode on the web), the original lossy artifacts are still in the decoded pixels. PNG preserves what's there bit-for-bit. To get a truly lossless source, you'd need a lossless WebP input or a different source format like PNG directly.

WebP uses advanced compression (predictive coding, block adaptation) to keep files small. PNG uses simpler lossless compression. The result: a 100 KB WebP typically becomes a 300–500 KB PNG. If file size matters more than lossless quality, use WebP to JPG instead — JPG is the smallest universal format.

Yes — if the source WebP has an alpha channel (transparency), the PNG output preserves it. EasyImg handles both lossy and lossless WebP inputs and passes the alpha channel through to PNG.

PNG when you need lossless quality, transparency, or plan to edit further — file is 3–5× larger than WebP and 5–10× larger than JPG. JPG when you need smaller files for sharing, uploading, or non-web use — small quality drop invisible at quality 90+. Pick PNG for source files; pick JPG for everything else.

EasyImg preserves EXIF, GPS, and ICC color profiles. WebP itself supports EXIF, and EasyImg carries it through to the PNG output. Color profiles (sRGB or Display P3) are preserved as well. Most online converters strip this metadata to save bandwidth.

Yes. Drag a folder of 5,000 WebP images into EasyImg, pick PNG, click Convert. Even at 0.4 seconds per file, 5,000 files finish in about 30 minutes on a modern laptop. Duplicates skipped, conflicts auto-rename.

Bottom line

WebP to PNG when you need lossless quality, transparency, or a master file for further editing. The file is 3–5× larger than the source WebP, but the pixels are preserved exactly. For non-design use, WebP to JPG is the more practical choice. EasyImg does both locally, so your images never leave your computer.
