How to convert JPG to WEBP

  1. Add your JPG files

    Drag one or more JPG files onto the dashed area, or tap it to pick them from your device.

  2. Choose WEBP and the options

    WEBP is already selected; the options hold the settings that matter for this conversion.

  3. Convert and download

    Press “Convert to WEBP”. When it’s done, download the files one by one or all together in a ZIP archive.

Good to know. A quality between 75 and 85 is usually the sweet spot: much lighter files and no difference to the naked eye.

JPG and WEBP compared

Source format

JPG

JPEG (Joint Photographic Experts Group)

The photo format par excellence. It compresses the image by discarding details the eye barely notices, so a 12-megapixel photo weighs only a few megabytes. Any device can open it, from an old phone to a photo lab’s printer.

WEBP

WebP (developed by Google)

A format designed for the web: at the same quality it’s on average 25-35% lighter than JPG and PNG, and it also supports transparency and animation. Every modern browser shows it, but some graphics programs and online services still don’t accept it.

Questions about JPG and WEBP

How much space will I save?

It depends on the photo, but at quality 80 a WEBP is often 25-35% lighter than the original JPG.

Are my JPG files uploaded to a server?

No. The conversion from JPG to WEBP happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.

How many files can I convert at once?

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.

Does it work on iPhone and Android?

Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.

What quality should I choose for WEBP?

For photos to share or post online, a quality between 75 and 85 gives light files with no visible flaws. For print or archiving go up to 90-95.

Do I need an internet connection?

Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
