Will resizing an image reduce its file size?

Yes. If you are shrinking the physical pixel dimensions of an image, it will naturally significantly reduce its overall file size in megabytes.

Can I scale images using percentages?

Yes! We have built-in quick scale buttons for 25%, 50%, 75%, and 200% dimensions, allowing you to resize without doing pixel math.

Yes! Our resizing engine fully respects and preserves alpha channels, meaning transparent backgrounds in PNGs will remain perfectly transparent.
