Resize Images Online — Free & Instant
Image Resizer Pro is a free, browser-based tool for resizing images by exact pixels, percentage scaling, or by constraining the longest or shortest side. It supports batch upload so you can process dozens of images simultaneously with the same settings — ideal for e-commerce product photos, blog thumbnails, and photography workflows.
Beyond resizing, it includes a full per-image editor: interactive crop with rule-of-thirds overlay and aspect-ratio locking, 90° rotation and custom angle, horizontal/vertical flip, brightness/contrast/saturation sliders, unsharp mask sharpening, watermark text, and a text overlay tool.
Output formats include JPEG, PNG, and WebP. The tool applies smart compression — when you significantly downscale an image, quality is automatically adjusted to produce the smallest reasonable file size. Download images individually or bundle them all in a ZIP archive.
