Frequently Asked Questions
Common questions about the free online batch image resizer.
Select the images, choose a target width, height or percentage, click Resize all and then
save each result from its own button.
Fit scales the whole image inside the target and can leave empty space. Fill scales it to
cover the target and crops the overflow.
The width and height are both multiplied by the percentage you enter, so 50 percent halves
the image and 200 percent doubles it.
Use PNG when the image has transparency or flat colours, and JPEG with quality around 0.85
for photos where a smaller file matters.
Usually yes, because fewer pixels means fewer bytes. The totals line shows how much the batch
shrank overall.
Six images are queued per run. Simply run the tool again for the next group using the same
settings.
No. Each image is decoded and redrawn on a local canvas in your browser, so nothing is ever
transmitted.
Yes. Scaling up invents new pixels, so the result looks softer. Keep percentage values at or
below 100 for sharp output.
Yes. The resizer is fully responsive and can select several photos from a phone or tablet
gallery.
