Portrait 9:16, lightweight
720×1280 is the vertical version of 720p: tall 9:16 for phone screens, story backgrounds and video thumbnails, at a file size that stays small. It’s a lighter alternative to 1080×1920 when you don’t need full resolution.
Fill the tall frame
A landscape or square photo needs cropping to go vertical — Fill covers the 9:16 frame, Fit pads it — and the preview shows exactly how it maps. Resizing runs entirely in your browser.
Frequently asked questions
- Does resizing happen on a server?
- No. Images are resized in your browser with high-quality step-down scaling for crisp results. Nothing is uploaded.
- Will resizing keep the aspect ratio?
- Yes by default. Enable “maintain aspect ratio” to fit within your target box without distortion, or turn it off to force an exact width and height.
- Are there presets for social media?
- Yes. There are presets for Instagram, Facebook, X/Twitter, YouTube and LinkedIn, plus common web, avatar and thumbnail sizes.
- Can I enlarge images?
- Yes, though enlarging cannot add detail that is not there. Downscaling produces the sharpest results.
- Can I resize images in bulk?
- Yes. Resize many images at once and download them together as a ZIP.
