Resize images to any width and height in your browser — no upload to servers needed
Images from smartphones and cameras are typically 3,000–6,000 pixels wide and 3–10 MB in size — far too large for web use, where page images should ideally be under 200 KB to avoid slowing page load. Resizing to the correct dimensions reduces file size dramatically and directly improves Core Web Vitals scores and user experience on mobile connections. This image resizer lets you specify exact pixel dimensions, a percentage scale, or select from common presets for social media, email, and web thumbnails. All resizing runs in your browser using the Canvas API — your images are never uploaded or stored on any server. Consider a few common scenarios where this tool earns its keep. A freelance web developer building a portfolio site needs hero images capped at 1,200 pixels wide so the page scores well on Lighthouse — dragging the original RAW exports here and outputting correctly sized JPEGs takes seconds. A small business owner preparing a product listing for an online marketplace needs images at exactly 1,000 by 1,000 pixels to satisfy the platform's upload requirements without distorting the aspect ratio. And a blogger writing a recipe post needs a consistent set of thumbnails at 800 by 600 pixels so the grid layout renders cleanly across every device without the CMS stretching mismatched originals. Bloggers, content creators, e-commerce sellers, and front-end developers will find this tool particularly useful, since image dimensions and file sizes come up in nearly every publishing workflow. Because all processing happens entirely in your browser, sensitive or confidential images — product photos before a launch, personal photos, client work under NDA — never leave your device. There is no account required, no file size limit enforced by a server, and no waiting for an upload to complete. Resize one image or a batch, download the results, and move on.
