PNG to WebP Converter
Short answer
Convert PNG, JPEG and other images to WebP, JPEG or PNG and resize them, right in your browser.
For WebP and JPEG. Lower values give smaller files with more visible artifacts.
Leave both empty to keep the original size. Images are scaled down to fit, never enlarged, and keep their proportions.
What It Does
Converts images to WebP, JPEG or PNG and can scale them down to a maximum width or height. It reads PNG, JPEG, WebP, GIF, BMP and AVIF files, several at a time, and does all the work in your browser: the images are never uploaded.
Why It Matters
Images are often the heaviest part of a page. WebP files are usually smaller than JPEG or PNG files of similar visual quality, and scaling an image down to the size it is displayed at saves even more. Smaller images load faster, which helps Largest Contentful Paint when an image is the largest element on the page.
How It Works
-
Choose images or drop them on the page
-
Pick WebP, JPEG or PNG, set the quality and, if you like, a maximum width or height
-
Your browser decodes each image, scales it down if needed and saves it in the new format
-
Compare the sizes before and after, then download each file

Frequently Asked Questions
Are my images uploaded?
No. Decoding, resizing and saving all happen in your browser, and the files never leave your device.
Why did I get a PNG instead of a WebP file?
Some browsers, Safari among them, cannot create WebP files and return a PNG instead. The tool tells you when that happens; a current Chrome, Edge or Firefox creates WebP.
Does converting keep EXIF data?
No. Saving the image again removes metadata such as camera details and GPS location. The image is first rotated according to its EXIF orientation, so it still shows the right way up.
Which quality setting should I use?
Start around 80 and compare the result with the original. Lower values give smaller files with more visible artifacts. The setting does not apply to PNG, which is lossless.
Can it convert to AVIF?
Not yet. Browsers can display AVIF, but none can create AVIF files from a web page, so the tool offers WebP, JPEG and PNG.
