Download🔒 Runs in your browser. Nothing you enter is uploaded or stored.
How to use it
Choose a photo, type a new width or height, pick a format, and download the result. With “keep proportions” ticked, changing one side updates the other so the image is not stretched. Quality applies to JPG and WebP; lower quality gives a smaller file.
Everything happens in your browser using the HTML canvas, so the image is never sent to a server. Resizing removes most metadata such as camera details and location, which is useful before sharing photos online.
FAQ
Can I make a small image bigger?
You can, but enlarging cannot add detail, so it will look softer.
Why does PNG make my photo file bigger?
PNG is lossless and suits graphics and screenshots. For photos, JPG or WebP are much smaller.
