Frequently asked questions
Is it really free?
Yes. There is no sign-up, no trial and no limit on the number or size of your images. The site is paid for by a single advertisement next to the tool.
Are my images uploaded?
No. Resizing happens on your own device, inside your browser. Your images are never sent to our servers. The only thing we count is how many images were resized, as a plain number.
Which formats are supported?
You can open JPG, PNG, WebP, GIF and BMP files, and AVIF where your browser supports it. You can save as JPG, PNG or WebP.
Will resizing reduce the quality?
Making a picture smaller keeps it sharp because the tool uses a high-quality filter. Making it larger cannot add detail that is not there, so enlarged pictures look softer. For JPG and WebP you can choose the quality yourself.
How do I get an image under a size such as 50 KB?
Turn on Limit the file size, type the number and press Resize images. The tool lowers the quality and, if needed, the dimensions until the file fits. Choose JPG or WebP for the best results, because PNG cannot be reduced that way.
Does it work on my phone?
Yes. The page works in current versions of Chrome, Safari, Firefox and Edge on phones, tablets and computers. Very large photos can be limited on older phones.
