Free Online WebP Tools
10 quick WebP utilities — convert, compress, resize and edit modern images
WebP is Google's modern image format, and it earns its keep on the web: files are typically 25–35% smaller than the equivalent JPG or PNG at the same visual quality, and it supports both transparency and animation. The catch is that not every app opens it and not every source produces it, so the common jobs are converting into WebP to save bandwidth, or out of it when something will not cooperate. These 10 tools handle both directions plus the everyday edits.
Every tool runs locally in your browser with JavaScript and the HTML canvas — your images are never uploaded to a server. That keeps unpublished graphics and client assets private, removes any file-size cap, and leaves no watermark on the output. Convert and edit as many images as you need.
Reach for WebP when page weight matters: converting a hero image or a gallery of PNGs to WebP can noticeably speed up a site without a quality hit you would notice. The Compress WebP tool lets you push the size down further with a quality slider, while the JPG and PNG bridges move images in whichever direction you need. Because WebP keeps an alpha channel, the transparency tools here work just like their PNG counterparts. For quick format and size work, these cover the routine.

How to Choose the Right Tool
To make a site lighter, start with the converters — JPG to WebP and PNG to WebP shift images into the smaller format, and Compress WebP pushes the size down further with a quality slider. Resize WebP trims the dimensions when the source is larger than it needs to be. Rotate WebP and Flip WebP correct orientation, and Add Text labels an image. The transparency pair mirrors PNG work: Make Transparent knocks a background out, Add Background fills one in. Grayscale is there for quick black-and-white recoloring.
Frequently Asked Questions
What is WebP and why use it?
WebP is a modern image format from Google that produces files roughly 25–35% smaller than JPG or PNG at similar quality, with support for transparency and animation. It is ideal for faster-loading web pages.
Are my images uploaded anywhere?
No — every tool runs entirely in your browser. Your WebP files stay on your device.
Does WebP support transparency like PNG?
Yes. WebP keeps an alpha channel, so the Make Transparent and Add Background tools work just as they would on a PNG.
What if an app will not open my WebP file?
Some older software still lacks WebP support. Convert it to JPG or PNG using our JPG and PNG tools, and it will open anywhere.
