imgsize is a free, browser-based image resizer and cropper built for online sellers, content creators, marketers and developers who need correctly sized photos for marketplaces and social platforms.
How it works
1. Drop or select a photo in your browser — no file upload to a server.
2. Pick a platform preset or enter a custom width and height.
3. Crop, zoom and adjust the frame, then export as PNG or JPEG with one download.
Built-in presets cover more than 85 common formats across 26 platforms, including Amazon product images, Etsy listings, Shopify store photos, Instagram posts and stories, TikTok videos, YouTube thumbnails, LinkedIn posts and banners, Facebook, Pinterest, X (Twitter) and eBay. You can also set any custom dimensions manually.
Privacy-first design
Every image is decoded, resized and exported locally in your browser using the Canvas API. The original photo never leaves your device, so there is no account to create, no upload queue, no watermark and no privacy risk from sending images to a third-party server. It works on desktop and mobile browsers.
