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.
Como funciona o redimensionamento de imagens
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 Dimensões to set specific width and height in pixels. Use Porcentagem 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.
