Why use this tool

  • No file size limit
  • Nothing is uploaded
  • No signup needed

WEBP was built for one job: getting images onto web pages with as few bytes as possible. It is typically 25–35% smaller than a JPG at the same visual quality, often far smaller than a PNG, and it keeps transparency, so one format can replace both on a website.

This WEBP converter takes JPG, PNG, HEIC and AVIF files and always writes a WEBP. It runs in your browser — nothing is uploaded, and there is no account, watermark or file limit.

How to convert an image to WEBP

  1. Add your image

    Drag a JPG, PNG, HEIC, AVIF or WEBP into the box, or click to browse.

  2. Convert to WEBP

    The output is fixed to WEBP. Press Convert to WEBP.

  3. Download

    The WEBP appears with its size next to the original's, so you can see the saving before downloading.

What converting to WEBP gives you

Smaller images load sooner, and on most pages the largest image decides how fast the page feels. Serving WEBP instead of JPG and PNG is one of the most direct ways to improve load time and the Largest Contentful Paint score Google measures.

Transparency is kept: a PNG logo or an AVIF cut-out converted to WEBP stays see-through. Dimensions do not change, and the image is written at a high quality setting, so photos look the same at normal size.

Converting from each format

From PNG the saving is usually largest — often 70% or more for photos and illustrations. From JPG, expect roughly a quarter to a third off. From HEIC, WEBP makes an iPhone photo web-ready in one step.

From AVIF the WEBP will usually be larger, because AVIF compresses harder still. Convert AVIF to WEBP when you need broader compatibility, not a smaller file.

When to convert to WEBP

  • Website images

    Hero images, blog photos and product galleries load faster as WEBP.

  • Online shops

    WooCommerce, Shopify and most platforms accept WEBP, and lighter product images help pages load on mobile.

  • Transparent graphics

    Logos and cut-outs stay transparent at a fraction of a PNG's weight.

  • Web apps and email builders

    Smaller assets mean faster apps and lighter bundles.

Frequently asked questions

Can I convert iPhone HEIC photos straight to WEBP?
Yes. The HEIC is decoded in your browser and written as WEBP at full size, so a photo from your camera roll is ready for a website in one step.
What quality setting is the WEBP saved at?
92 on a 0–100 scale, at the original dimensions. That is high enough that photos look unchanged; for a smaller file, give the WEBP a size target in Compress Image.
Can every browser save WEBP files?
Chrome, Edge and Firefox can. A few browsers cannot write WEBP; if yours is one, the tool tells you rather than saving a different format.
Is this the same as the JPG to WEBP converter?
It uses the same engine. JPG to WEBP is set up for photos already in JPG; this page also takes PNG, HEIC and AVIF files, and a mix of them in one batch.
Can I mix PNG, JPG and HEIC files in one go?
Yes. Add them together and each one becomes a WEBP; download them one at a time or all in a ZIP.
Do my images leave the device?
No. Converting to WEBP happens in this browser tab, so images that are not published yet, such as product photos before a launch, stay private.
