Crop, rotate, and frame pictures with aspect ratio presets for avatars, social media posts, and banners.
The Image Cropper lets you trim, rotate, and reframe photos easily in your web browser. You can select standard aspect ratios—like 1:1 for profile pictures, 16:9 for YouTube thumbnails, or 4:3 for standard prints—or drag the crop handles freely.
Because all editing runs locally inside your browser using HTML5 canvas, your personal photos, selfies, and private scans never leave your computer or phone.
Users crop portraits into exact 1:1 squares for Instagram, WhatsApp, and Slack profile photos.
Bloggers crop landscape photography into 16:9 hero banners for blog headers and social cards.
Professionals crop background tables and clutter out of scanned receipts and documents.
Select or drag your image into the workspace.
Choose an aspect ratio preset or drag the corner handles to frame your image.

MWT Labs tools are built using modern web primitives—including WebAssembly, Web Workers, and native HTML5 Canvas / Cryptography APIs. When you process images, parse PDF documents, format JSON payloads, or calculate financial schedules, execution happens strictly within your local browser memory sandbox.
The tool loads your image into an interactive HTML5 canvas where you can drag handles to select the exact crop area, rotate the photo, or choose preset aspect ratios like 1:1, 16:9, or 4:3.
