How to Convert WebP — JPG·PNG ↔ WebP for Free

Have you ever loaded a page full of images and watched it crawl, or been sent a .webp file that just won't open? WebP is Google's modern image format — smaller at the same quality — but some programs still can't read it. This guide covers both directions: shrinking JPG·PNG into WebP, and turning WebP back into JPG·PNG. No install, no sign-up.

What is WebP, and why use it?

• Smaller files — Created by Google, WebP is usually 25–35% smaller than JPG·PNG at the same quality. Pages load faster, and speed affects search ranking and bounce rate.
• Supports transparency — Like PNG, WebP can keep a transparent background, so it works for logos and icons too.
• The catch is compatibility — Older viewers and some office apps or messengers can't open WebP. When that happens, just convert it back to JPG·PNG.

How to convert — 2 steps

1. Upload and pick the direction — In WebP conversion, upload your image and choose "JPG/PNG → WebP" or "WebP → JPG/PNG."
2. Download — Grab the converted image and you're done. No install or sign-up.

Tools that work well together

To shrink files even more, use image compression to adjust quality and size (it can also auto-compress to a target size). If your iPhone photo is HEIC and needs converting first, run it through HEIC → JPG conversion.

Frequently asked questions

Q. Why won't my WebP file open?
Older image viewers and some office apps or messengers don't support WebP. Convert the WebP to JPG·PNG and it will open anywhere.

Q. Is the transparent background kept?
Yes. Transparency is preserved when converting between PNG and WebP.

Q. Does quality drop?
WebP holds the same quality in a smaller file. To make it even lighter, run the result through image compression to lower the quality further.

Q. Is it free? Is my file stored?
It is free, and uploaded images are used only for the conversion and are not stored on the server.
