Does resizing images lower quality?

Downscaling reduces pixel count but keeps images sharp when using our high-quality bicubic smoothing filter. Upscaling beyond original dimensions will interpolate pixels.

Are my uploaded photos private?

Yes! All resizing and cropping operations execute completely in your local browser sandbox. Your images are never transmitted across the network.

Smart Image Resizer & Aspect Ratio Cropper

Resize by exact pixels, percentage scale, or social media presets with aspect ratio crop overlays.

Security Guarantee: 100% Client-Side In-Browser Execution. Computations run locally within browser RAM. Zero remote telemetry.

Technical Overview & Architecture

Resize and crop images with bicubic resampling directly in your browser. Scale by exact dimensions with aspect ratio lock, scale by percentage (25% to 200%), choose social media presets (YouTube Thumbnail, Twitter Header, OpenGraph, Instagram), or perform custom aspect ratio cropping.

The image is loaded into an in-memory Canvas element. When resizing or cropping, the canvas context applies high-quality image smoothing algorithms and extracts the selected sub-rectangle or resampled dimensions directly into your chosen image format.
