How do I convert an image to WebP?

To convert an image to WebP, drop your JPG or PNG files into this free converter, keep WebP selected (quality 80 suits most photos) and download the results one by one or as a ZIP. Up to 50 images at a time. Everything runs in your browser, so your images are never uploaded.

Procedure

How to convert images to WebP

Three steps on a phone or a computer. No account, no upload, no waiting in a queue.

  1. Step 1: Add your images

    Drop JPG, PNG, GIF, BMP, AVIF or SVG files onto the box, choose them from your device, or paste a screenshot with Ctrl+V. You can add up to 50 images at a time.

  2. Step 2: Pick a format and quality

    WebP at quality 80 suits most photos. Lower the quality for smaller files, set a max width or height to shrink large photos, and choose whether to keep transparent backgrounds.

  3. Step 3: Download the results

    Each image shows its new size and how much space you saved. Download images one at a time, or all of them together in a single ZIP file.

Why convert JPG and PNG to WebP?

WebP is an image format from Google built for the web. It does the jobs of JPG and PNG in one format, with smaller files for the same look.

Smaller files
Google’s own tests found lossy WebP files 25–34% smaller than JPGs of the same visual quality, and lossless WebP 26% smaller than PNG.
Faster pages
Lighter images load sooner, which helps Largest Contentful Paint. PageSpeed Insights flags JPG and PNG under “Serve images in modern formats”.
Transparency included
WebP keeps alpha transparency like PNG while compressing like JPG, so logos and cut-out product shots no longer need heavy PNGs.
Works everywhere
Chrome, Edge, Firefox, Opera, Samsung Internet and Safari 14+ on iPhone, iPad and Mac all show WebP: well over 95% of people online.

Figures from Google’s WebP documentation. Your savings depend on the image: busy photos and uncompressed PNG or BMP files shrink the most.

FAQ

WebP converter questions

About privacy, quality settings, transparency and which browsers support WebP.

Are my images uploaded to a server?

No. The conversion runs entirely in your browser, using the image encoder built into it. Your files never leave your device, nothing is stored anywhere, and once the page has loaded the converter even works offline.

What quality setting should I use for WebP?

For photos, 75 to 85 looks the same as the original at normal viewing sizes while cutting the file size a lot. The default is 80. For screenshots, logos or images with small text, try 90 or higher. If a file comes out larger than the original, lower the quality.

Why is my WebP file bigger than the original?

This happens when the original was already squeezed hard, such as a small JPG saved at low quality, or a simple PNG graphic with only a few colors. Re-encoding at a high quality cannot make those smaller. Lower the quality slider, or keep the original file for that image.

Does WebP keep transparent backgrounds?

Yes. WebP supports transparency just like PNG, and “Keep transparent background” is on by default. Turn it off to fill transparent areas with a solid color. JPG cannot store transparency at all, so when you convert to JPG the transparent areas are filled with the color you choose, white by default.

Can I convert iPhone HEIC photos to WebP?

Only if your browser can open HEIC files. Safari on iPhone, iPad and Mac can. Chrome, Edge and Firefox on Windows and Android usually cannot, and the converter will tell you when that happens. You can also set your iPhone to shoot JPG under Settings, Camera, Formats, Most Compatible.

Do all browsers support WebP images?

Yes, every current browser displays WebP: Chrome, Edge, Firefox, Opera and Samsung Internet, plus Safari 14 and later on iPhone, iPad and Mac. That covers well over 95% of people browsing the web today. If you need to support very old browsers, serve WebP inside a picture element with a JPG fallback.

Does converting remove EXIF data like GPS location?

Yes. The browser redraws only the pixels, so camera details, GPS location and other EXIF metadata are left out of the new file. Photo orientation is applied before converting, so pictures taken sideways still come out the right way up.

Is there a limit on file size or the number of images?

You can convert up to 50 images per batch, then clear the list and add more. There is no file size limit beyond your device’s memory, but browsers cannot handle images larger than about 16,000 pixels on a side. For huge images, set a max width or height first.

When to keep JPG or PNG

WebP is the better choice for websites and apps. A few places still expect the older formats: some email programs (older desktop Outlook in particular) don’t show WebP images, some upload forms and print services only accept JPG or PNG, and design tools may not open WebP files.

Keep your originals too. Lossy WebP throws away detail you can’t get back, so convert copies for publishing and leave the source photos as they are. If you need a JPG or PNG later, pick it in the format switch above.
