Frequently Asked Questions

How do I resize an image online for free?

Upload your image to Socera's Resize Image tool, enter the target width and height (or percentage), toggle aspect ratio lock, and download your resized image.

Can I resize an image without distorting it?

Yes. Enable the aspect ratio lock (the chain icon) to maintain the original proportions when resizing. Change one dimension and the other adjusts automatically.

Instagram square: 1080×1080px. Twitter header: 1500×500px. Facebook cover: 820×312px. LinkedIn banner: 1584×396px. YouTube thumbnail: 1280×720px.

Can I resize multiple images at once?

Images up to 50 MB per file are supported. For extremely large RAW photography files, we recommend converting to JPG or PNG first.
