WebP Converter online
Convert images to WebP — the web's modern format that usually beats JPEG on size at the same quality — or convert WebP files back to JPG/PNG for tools that cannot read them.
How to use this tool
- Choose an image (JPG, PNG or WebP).
- Click Convert. The image is re-encoded in the target format on a local canvas.
- Download the converted file from the result.
Common uses
Modernising a site's images for page-speed scores, shrinking photo uploads for a CMS, rescuing a WebP file that an editor or office app refuses to open, and preparing images for platforms with format whitelists.
How it works
WebP compresses with a newer codec than JPEG and supports both lossy and lossless modes plus transparency — the combination that let it replace both JPEG (photos) and many PNGs (graphics with alpha). Typical photo conversions save 25–35% against an equivalent-quality JPEG. The catch is compatibility at the edges: every modern browser displays WebP, but older desktop software, some email clients and a few social pipelines still reject it — which is why this converter runs in both directions.
Worked example
A product photo at 900 KB as JPEG comes back around 600–650 KB as WebP at comparable visual quality; across a 40-image category page that is roughly 11 MB of transfer removed. In the other direction, a WebP screenshot saved from a browser converts back to a PNG that any editor opens — a 30-second detour that beats fighting a format refusal.
Privacy and browser processing
Your image is converted in your browser on a local canvas — it is never uploaded or stored.
Frequently asked questions
Is WebP supported everywhere now?
In browsers, effectively yes — Chrome, Edge, Firefox and Safari (since version 14) all display it. The holdouts are older desktop apps, some email clients and embedded systems. For the open web, WebP is a safe default; for email and office documents, JPEG remains the lingua franca.
Does converting to WebP lose quality?
The lossy mode discards a little, like JPEG does, tuned to be invisible at normal settings; the pixels a JPEG already lost are not restored either way. Converting a JPEG to WebP keeps its existing artifacts and shrinks the container around them.
Why is my WebP bigger than the original PNG?
For flat graphics with few colours, PNG's palette-style compression is extremely efficient and a lossy WebP at high quality can exceed it. Content decides the winner; the converter makes switching cheap enough to test.
Can it convert an animated WebP or GIF?
The canvas pipeline handles still images; an animated source converts using its first frame. For animation-preserving conversion, dedicated tooling (ffmpeg, cwebp with filters) is the route.
Is my image uploaded?
No. Conversion runs on a canvas in your browser; the image never leaves your device.
