How to convert images
- Drop a batch in and choose the output format: JPEG, PNG, or WebP.
- For JPEG or WebP, set the quality; PNG is lossless, so that control is hidden when you pick it. You can also convert to grayscale, or (for PNG output) make a white background transparent.
- To shrink the images at the same time, set a max width and height under resize.
- Process the batch and download the results individually or all at once.
When to use it
WebP is the usual target for the web. At similar quality it is roughly 25 to 35% smaller than the equivalent JPEG or PNG, so converting a folder of screenshots or photos to WebP trims a page’s image weight with no obvious drop in quality. Converting back to PNG or JPEG helps when an older app or upload form won’t accept WebP.
“Make white background transparent” lifts a logo or icon off a solid white backdrop into a PNG you can lay over any color, with no image editor involved. Grayscale is useful for normalizing a set of scans or preparing assets for single-color print.
Frequently asked questions
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using the canvas API. Your images never leave the page and nothing is sent anywhere.
Which formats can I convert between?
JPEG, PNG, and WebP. Drop in any image your browser can open and choose the output format.
Why is the quality option hidden when I pick PNG?
PNG is lossless, so a quality setting has no effect. Quality applies only to JPEG and WebP, where it trades file size against detail.
Can I convert several images at once?
Yes. Add multiple files and process them as a batch, then download each result or all of them together as a ZIP.
Does converting to JPEG keep transparency?
No. JPEG has no alpha channel. To keep transparency, convert to PNG or WebP instead.
