Resize Image

Change image dimensions by pixels or percentage. Maintains aspect ratio by default.

About Resize Image

Every platform wants images at a different size — profile photos, marketplace listings, email signatures, and print all have their own requirements. Resizing to the exact pixel dimensions avoids ugly automatic cropping and keeps uploads within size limits.

This resizer lets you enter exact width and height or scale by percentage, with an option to lock the aspect ratio so photos don't stretch. Resampling happens in your browser at high quality, and the original file stays untouched.

How to use Resize Image

  1. 1

    Load the image

    Drop in the photo or graphic you need at a different size.

  2. 2

    Enter target dimensions

    Type an exact width/height in pixels, or scale by percentage. Lock the ratio to prevent distortion.

  3. 3

    Resize

    The image is resampled smoothly in your browser.

  4. 4

    Download

    Save the resized copy, correctly dimensioned for wherever it's going.

Tips for better results

  • Always shrink rather than enlarge when possible — upscaling can't invent detail that was never captured.
  • Keep the aspect ratio locked for photos; unlocked resizing squashes faces noticeably.
  • Common targets: 1920×1080 for full-screen, 1200×630 for social link previews, 800px wide for blog content.
