About ImageSizr.com

Our Mission

ImageSizr.com was built with a simple goal: give users a fast, privacy-first way to resize and optimize images directly in the browser. Too many image tools require account sign-ups, upload files to remote servers, or lock features behind paywalls. ImageSizr takes a different approach.

Every feature is free and available immediately — no subscription tiers, no registration walls, no hidden costs. Whether you are a photographer preparing client proofs, a designer resizing assets, a marketer creating social-media graphics, or anyone who works with images, ImageSizr is built for you.

The result is an all-in-one image toolkit that respects your privacy while delivering the resize, crop, compress, rotate, and flip capabilities you need in a single product.

Privacy-First by Design

Privacy is not an afterthought at ImageSizr — it is the foundation of the architecture. All image processing happens client-side using canvas-based operations in your browser. Your images never leave your device. No image data is stored, logged, or transmitted to any server for processing.

Even when you import images from external sources like a URL, Google Drive, Dropbox, or OneDrive, the files are fetched to your browser and processed locally. The server-side API routes under /api/import/* handle the fetch, but the actual image manipulation always runs on your machine.

For full details on how your data is handled, read our Privacy Policy. You can also learn more about the technical approach in our guide on how private browser image processing really is.

Everything You Need in One Place

ImageSizr.com combines five core image tools with flexible format controls and multiple import options:

• Resize — set custom dimensions in pixels, centimetres, inches, or millimetres. Scale by percentage with quick presets at 25%, 50%, and 75%. Lock aspect ratio to maintain proportions. Use social-media presets for Instagram, Facebook, Twitter/X, and YouTube, or device presets from HD to 4K and specific phones, tablets, and laptops. Bulk resize up to 5 images at once.
• Crop — freeform cropping or preset aspect ratios (1:1, 4:3, 16:9, 3:2, 2:3) powered by an interactive CropperJS editor.
• Compress — quality slider from 0–100% with real-time file-size preview. Export as JPEG, PNG, or WebP for optimal size control.
• Rotate — quick 90-degree increments or a fine-tune slider from -45° to +45° in 0.5-degree steps, with a grid overlay for precise alignment.
• Flip — horizontal and vertical mirroring with instant CSS-transform preview and a clear status indicator.

Export as the original format, JPEG, PNG, WebP, or ICO (multi-size icon generation at 16, 32, 48, 64, 128, and 256 px). Upload via drag-and-drop, browse, clipboard paste, URL, Google Drive, Dropbox, or OneDrive. Learn more about import options in our guide on importing images from URL, Dropbox, Drive, and OneDrive.
