Free Image Resizer – Resize to Exact Pixels or Percentage in Seconds

Resizing an image changes its pixel dimensions. This is different from compressing — resizing changes the actual number of pixels, while compression changes how those pixels are encoded. You need to resize when: a platform specifies exact pixel dimensions (Twitter header: 1500×500px, LinkedIn profile: 400×400px, Instagram post: 1080×1080px), when you need to reduce file size by reducing pixel count, or when preparing images for specific print sizes at a given DPI.

This tool resizes using the browser Canvas API with high-quality bicubic downsampling — the same algorithm used by professional image editors — to minimize quality loss during resizing. Choose exact pixels, percentage scale, or fit within a maximum dimension while preserving aspect ratio. Output as JPG, PNG, or WebP. Your image never leaves your browser.
