Image Resizer
Choose an image and a maximum width or height. It is scaled on this device with the aspect ratio kept, unless you turn that off, and downloaded as PNG, JPEG or WebP. Nothing is uploaded.
Frequently asked questions
Is the file uploaded?
No. The picture is decoded and scaled in this browser tab. Closing the page drops it.
Will a small image be enlarged?
Not while keep aspect ratio is on. The image only shrinks to fit inside the size you set. Turn it off to set an exact size.
Why is the file size bigger after resizing?
PNG is lossless and can be larger than the original JPEG. Choose JPEG or WebP for photos, or use Image Compressor.
