100% Client-Side Privacy
Images are scaled directly inside your browser using the local HTML5 Canvas API. Your pictures are never sent to external servers.
Social Preset Profiles
Auto-generate target width and height for popular services such as Instagram post/story, YouTube channel/thumbnail, Facebook cover, and more.
Resampling Control
Choose Bilinear high-quality smoothing for smooth transitions, or Nearest-Neighbor to prevent blurring on pixel art and crisp text diagrams.
Aspect Sizing Methods
Decide whether to letterbox with margins (Aspect Fit), crop edges to match output scale (Aspect Fill), or stretch image pixels directly.
