Why resize images?
Images that are too large slow down websites, waste bandwidth, and may not meet platform requirements. Resize images for social media profiles, e-commerce product photos, email attachments, and web optimization.
Comment fonctionne le redimensionnement d'images
Our tool uses Canvas API to resize images at the pixel level. When maintaining aspect ratio, one dimension auto-calculates to prevent stretching. Choose from exact pixel dimensions or percentage scaling. Output in your preferred format — keep the original or convert to WebP for optimal web delivery.
Resize modes: exact, percentage, and fit
Choose Exact Dimensions to set specific width and height in pixels. Use Pourcentage mode to scale by a uniform ratio (e.g., 50% for half size). Fit To Box mode resizes to fit within a bounding box while preserving aspect ratio — ideal for creating thumbnails or social media profile pictures.
