How to convert WebP to JPG on Windows

Short answer: right-click → Open with → Paint and Save as JPEG works for one file if your Windows is new enough — for a batch, a quality-preserving or offline job, use a free tool like WebP Converter: WebP → PNG/JPG and JPEG/PNG → lossless WebP, all locally, no uploads.

Why you keep meeting .webp

WebP is what the web actually serves now: sites convert images to it automatically because it is dramatically smaller than PNG and JPEG at similar quality. When you save one of those images, the browser writes .webp — and then Windows tooling stumbles: older Photos viewers refuse it, half the editors cannot import it, messengers and upload forms with format checks reject it.

The reverse case is just as common: you need images for a site or app and want the smallest files.

Method 1: built-in (one file at a time)

On current Windows 10/11 the Photos app and Paint can open WebP. In Paint: Open the file → File → Save as → JPEG picture. Two catches: strictly one file per round of clicks, and Paint re-compresses — quality settings are broad and there is no batch.

Method 2: WebP Converter — batch, lossless, offline

Download free — WebPConverter-Setup.exe

1. Add images. WebP files for conversion back, or JPEG/PNG/BMP/GIF to convert to WebP.
2. Pick the direction. “Convert from WebP” → PNG (pixel-perfect) or JPG with a quality slider. “Convert to WebP” is lossless — no quality slider needed.
3. Press Convert. Each row shows the before → after sizes and the percentage saved. Files are written next to the originals; nothing is overwritten.

Why this beats the online converters that fill the search results: your files are never uploaded anywhere (client mock-ups, documents and photos stay on your PC), the app works offline, and the batch is unlimited. And unlike “save as webp” in editors, the To-WebP direction here is lossless — the pixels are stored exactly, so a round trip WebP → PNG → WebP never accumulates quality loss.

Reading the result rows

• PNG → WEBP · 412 KB → 96 KB · −77% — graphics and screenshots usually shrink dramatically.
• JPG → WEBP · 2.1 MB → 2.3 MB · +10% — normal for photos: JPEG is already lossy, and lossless WebP can be slightly bigger. For publishing photos, a lossy WebP encoder would win — that is a different tool's job; this converter never sacrifices quality.
• When in doubt, keep both: originals are never touched.

FAQ

Does converting lose quality?

To WebP: no — the encoder is lossless. From WebP: PNG keeps every pixel; JPG depends on the quality slider you choose.

Is there a built-in Windows batch converter?

No. Windows can open and re-save individual WebP files in Paint or Photos; batch conversion requires a third-party tool.

Can I convert WebP to PNG instead of JPG?

Yes — pick PNG in “Convert from WebP” and the output is pixel-identical to the decoded source.
