⚙️ Understanding the Options

Unit Selection

Pixels (px): Best for digital use like websites, social media, and screen display. One pixel equals one dot on your screen.

Inches (in): Ideal for printing. Combined with DPI setting, ensures your image prints at the exact physical size you need.

Centimeters (cm): International standard for print dimensions. Perfect for passport photos and official documents.

Aspect Ratio

When enabled, changing width automatically adjusts height (and vice versa) to maintain the original image proportions. Disable this to create custom dimensions that may stretch or compress the image.

Image Quality

Controls JPEG compression level. 100% is maximum quality (larger file), while lower values reduce file size at the cost of some detail. For web use, 70-85% often provides the best balance.

DPI (Dots Per Inch)

Only relevant when using inches or centimeters. Standard DPI values: 72 for web, 150 for draft prints, 300 for professional printing, 600 for high-end commercial printing.

Preset Sizes

Passport (600x600 px): Standard passport photo size for most countries.

Thumbnail (150x150 px): Small preview images for websites and galleries.

HD (1920x1080 px): Full HD resolution for monitors and video thumbnails.

Instagram (1080x1080 px): Perfect square format for Instagram posts.

❓ Frequently Asked Questions

Is my image uploaded to a server?
No! All image processing happens directly in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
The tool supports all common image formats including JPG/JPEG, PNG, GIF, WebP, and BMP. The output will be in JPG format for optimal compression.
Why should I use pixels vs. inches or centimeters?
Use pixels for digital purposes (websites, social media, screens). Use inches or centimeters when you need to print the image at a specific physical size. The DPI setting connects these units - at 300 DPI, a 3-inch width equals 900 pixels.
What quality setting should I use?
For web use, 70-85% provides a great balance. For printing or archival, use 90-100%. For thumbnails or previews, 50-70% is often sufficient. Higher quality means larger file sizes.
Can I batch resize multiple images?
Currently, the tool processes one image at a time. For batch processing, you can resize each image individually using the same settings for consistency.
Will resizing reduce image quality?
Enlarging images can reduce quality as pixels are interpolated. Reducing size generally maintains quality well. The quality slider controls compression, not scaling quality. For best results, avoid enlarging images beyond their original size.
What is the maximum image size I can process?
The tool can handle most standard images up to 20-30 megapixels. Very large images may take longer to process depending on your device capabilities.
How do I create a passport size photo?
Simply click the "Passport (600x600)" preset button, or manually enter 2x2 inches (or 51x51mm) with 300 DPI. Most countries accept this standard size for passport photos.
