Frequently asked questions

Will resizing reduce file size?

Smaller pixel dimensions usually reduce file size, but format and quality still matter. Compress after resizing for web use.

Does resizing upload my image?

Simple resize workflows run in your browser. Check the tool’s processing label on the page for the current mode.

What size should I use for websites?

Match the display size on the page — often 1200–1600px wide for hero images and 400–800px for content images — then compress.

Can I resize for social media?

Yes. Use platform guidelines (for example 1080×1080 for square posts) and crop afterward if the framing needs adjustment.
