Resize

px / % / fit-to-width / fit-to-height · batch

Drop images and resize them — by pixels, by percent, or by fitting to a target width/height while preserving aspect ratio. Output keeps the same format as the source.

When to use this tool

Resize before posting to social media (which has size caps), uploading to a CMS that resizes server-side anyway (faster upload), or generating multiple sizes for responsive web design.

Modes

• Exact pixels: stretch to W×H. May change aspect ratio.
• Percent: e.g. 50 = half size.
• Fit to width: set width, height auto-calculated to preserve aspect.
• Fit to height: set height, width auto-calculated to preserve aspect.

Use cases

• Hero images for web. Fit-to-width 1920.
• Thumbnails. Fit-to-width 200, batch mode.
• Social uploads. Fit-to-width 1080 for Instagram-friendly sizes.
• Email-ready. Percent 50 to slim a stack of phone photos.
