FAQ
Can I keep the aspect ratio?
Yes. With 'Keep aspect ratio' on, entering only a width (or height) calculates the other side automatically.
Are there social media presets?
Yes: X (1200×675), Instagram square (1080×1080) and portrait (1080×1350), and Full HD (1920×1080). Recommended sizes can change when services update their specs.
Can I enlarge an image?
You can scale up to a larger size, but quality cannot exceed the original — small images may look blurry when enlarged.
Can I resize multiple images at once?
Yes. Select multiple files to apply the same settings to all of them and download the results as a ZIP.
