Documentation
Image Resizer lets you quickly scale one image by pixels, percentage, or presets with real-time comparison for web, social, and document workflows.
Resize Modes
- Stretch: force output size directly, fastest but can distort.
- Fit: keep aspect ratio and fit inside target area, may leave blank space.
- Crop: keep ratio and cover target area, trims edge content.
- Fill: keep ratio and fill remaining area with background for cover layouts.
Use Cases
- Standardize ecommerce product image dimensions
- Prepare social media covers, avatars, and post images
- Match upload size constraints for IDs, forms, and portals
Tips
- Enable lock ratio to avoid shape distortion in portraits.
- Use PNG when transparent background should be preserved.
- Start from a preset and then fine tune width and height.
- Heavy upscaling may reduce sharpness, compress if needed.
Privacy
All resizing is performed locally in your browser and source files are not uploaded to the server.
