Guide

Resize images to exact dimensions online

Change width and height in pixels with optional aspect-ratio lock. This free image resizer helps you prepare thumbnails, social crops and print-ready sizes without desktop software.

Exact sizes for platforms and print

Every channel wants different dimensions: profile photos, Open Graph images, ads and marketplace listings. Resizing precisely avoids awkward platform crops after upload.

Lock aspect ratio or set custom pixels

Keep proportions when you only know one side, or unlock to force an exact frame. Export as JPEG, PNG or WebP depending on whether you need transparency or smaller photos.

  • Social profile and cover images
  • Blog thumbnails
  • Ecommerce variants
  • Presentation assets

Processed on your device

Upload stays local. Resize large assets carefully on low-memory phones; desktop browsers handle bigger images more comfortably. Download when the preview matches your target size.
