Everything you need to know
Drag & Drop Upload
Click the upload area or drag an image onto it. The tool accepts PNG, JPG, WebP, and GIF files up to 50 MB. Your original image is displayed alongside its dimensions and file size.
Aspect Ratio Lock
By default the aspect ratio is locked — change the width and the height updates automatically. Unlock it to stretch or squish the image to any custom dimensions.
Quick Resize Presets
One-click presets scale the image to 25%, 50%, 75%, 100%, 150%, or 200% of its original size. Perfect for quickly shrinking large photos for web use.
Format & Quality Control
Choose between PNG (lossless), JPEG, or WebP. For JPEG and WebP, adjust the quality slider from 10% to 100% to balance file size and visual fidelity.
Client-Side Processing
All resizing happens in your browser using the Canvas API. No images are sent to any server, so your files remain completely private.
