This page resizes Image Online files specifically. The Image Online format is decoded, scaled and re-encoded entirely inside your browser, so the file never travels anywhere and the output stays in Image Online.
How it works
- Select one or more Image Online files.
- Enter the width or height you want, in pixels or as a percentage.
- Keep the aspect ratio locked unless you specifically need to distort the image.
- Download the result as Image Online.
Good to know
Resizing a Image Online file re-encodes it, which means the compression is applied again. Going down in size usually shrinks the file considerably; going up will make it larger without adding real detail.
Frequently asked questions
Does resizing Image Online lose quality?
Scaling down looks clean because you are discarding pixels you no longer need. Scaling up cannot add information, so a Image Online enlarged well beyond its original size will look soft.
Can I resize several Image Online files at once?
Yes — select as many Image Online files as you like and the same dimensions are applied to all of them.
