Exact dimensions in a couple of clicks
The Image Resizer changes the width and height of JPG, PNG, WebP and GIF pictures to whatever your project needs. Type an exact pixel size, keep the aspect ratio locked so nothing gets stretched, or scale by percentage — the tool resamples the image cleanly so edges stay crisp and text in screenshots stays readable.
Resizing down is also the most underrated compression trick there is. A 4000-pixel camera photo displayed on a website at 1200 pixels wastes more than 80% of its bytes; resizing first and compressing second produces dramatically smaller files than compression alone. The tool always shows the target dimensions before you process, so what you see is exactly what you get.
Everything happens on your device: the picture is decoded, resampled and re-encoded by your browser without ever touching a server. That makes the tool safe for unreleased product shots, personal documents and any other image you would rather not upload anywhere.
Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
