Saved a picture from a website and ended up with a .webp file that your program will not open? Turn it into a JPG here.

    Everything you enter is processed in your browser and is never sent to a server.

    Browsers:Chrome57+Edge79+Firefox52+Safari15+Opera44+Samsung Internet7.0+BrowsersYour browser must also be able to show WebP pictures, which the data above does not cover.

    How to use

    1. Drop your .webp files onto the box, or choose them. Up to 50 at once.
    2. Choose the quality (90 is a good start) and the background color for any transparent area.
    3. Download each JPG, or all of them as a ZIP.

    Examples

    banner.WEBP, converted to JPG
    → banner.jpg
    A WebP with a transparent background, background color white
    → The picture on white
    WebP can be transparent and JPG cannot.
    An animated WebP
    → A JPG of its first frame
    A JPG is a single picture, so only the first frame is kept.
    A WebP logo with a soft shadow, background color black
    → The logo and its shadow on black
    Partly transparent pixels are blended with the background colour, so a soft shadow that showed on white all but disappears on black.
    A 1200 × 800 WebP at quality 90, Keep original size
    → A 1200 × 800 JPG
    The size in pixels is unchanged, only the format and the file size differ.

    How it works

    This page is the image converter with WebP to JPG already chosen. Your browser decodes the WebP, and the JPG is written by MozJPEG, an open-source encoder. Transparent pixels are painted onto your background color first.

    File naming, size calculations and the encoder output are tested.

    What happens to a transparent picture

    A JPG has no way to store transparency, so the page first paints the chosen background colour and draws the WebP over it. Fully transparent pixels become that colour. Partly transparent pixels, such as the edge of a logo or a shadow, are blended with it. That is why the colour matters: it is not a fill behind the picture that you can change later, it is baked into the pixels of the JPG.

    Quality and size

    The JPG is written in the progressive form, which loads from blurry to sharp on a slow connection. It is the setting MozJPEG uses by default. Quality 90 is the default here because pictures that were saved as WebP are often meant to look clean. A JPG made from a WebP that was itself heavily compressed does not become better, so a higher quality only makes the file bigger.

    If you want Try
    A copy to send by e-mail 80 to 85, and a smaller size
    A file for a program that rejects WebP 90
    The cleanest copy you can make 95, and expect a large file

    When another format fits better

    If the picture is a logo, an icon, a screenshot or has transparency you must keep, a JPG damages it, and the WebP to PNG page is the better choice. JPG is for photographs.

    Frequently asked questions

    What is WebP?
    WebP is a picture format from Google that makes web pages load faster. Photos are usually smaller than the same photo as JPG. Every current browser shows it, but many older programs, e-mail clients, print services and upload forms do not.
    Why did I get a .webp file when I saved a picture?
    Many websites send WebP to browsers that support it, so Save Picture As gives you a WebP even if the page looked like a JPG. Converting it solves that.
    Does converting lose quality?
    A little, since the WebP is written again as a lossy JPG. At quality 90 the difference is hard to see. If the WebP was lossless and you want to keep it exact, use PNG instead, with the image converter.
    What happens to transparency and animation?
    JPG has neither. Transparent areas are filled with the background color you pick, and an animated WebP gives only its first frame.
    Which background colour should I pick?
    The one the picture will sit on. White suits documents and most web pages, black suits a dark page. If the JPG will later sit on a different colour from the one you chose, the soft edges of a logo show a thin fringe of your colour, because the edge pixels were blended with it.
    Why is the JPG bigger than the WebP?
    WebP compresses more efficiently than JPG, and Google says it typically achieves about 30% more compression than JPEG. To get a similar look, the JPG needs more bytes. Lower the quality or the size if the JPG is too large.
    What quality should I choose?
    90 is a good start, and the page shows the size of each result so you can try another value. 100 is not lossless in JPG and makes a much larger file for little visible gain, while lower values show more blocky patches on smooth areas.
    Can this page open a WebP that my browser cannot show?
    No. The browser decodes the WebP, so a very old one that cannot display WebP cannot read it here either. Browsers that support WebP are all current versions of Chrome, Edge, Firefox, Opera and Safari 14 or later on macOS Big Sur or later.
    Are my pictures uploaded?
    No. They are converted in your browser.

    Guides

    Version history
    • 1.0.4 — Adds how transparent pictures are flattened onto the background colour, how to choose the colour and the quality, browser support for WebP, and more examples and questions.
    • 1.0.3 — Puts the format and quality options and the size options on one line on a wide screen, instead of two lines with empty space beside them.
    • 1.0.2 — Makes the search title and description state the supported task, key formats and privacy benefit more clearly.
    • 1.0.1 — Reports conversion completion and failure to connected workflows, so batch runs wait for the full result and ignore cancelled or superseded work.
    • 1.0.0 — First release.
