Tweetkar Advanced Image Resizer 3.5cm x 4.5cm

The standard size for passport photos varies by country, but 3.5cm x 4.5cm is one of the most common dimensions used worldwide. This size is accepted for passports, visas, and other identification documents in many countries including the United States, Canada, and most European nations. Tweetkar tool is specifically designed to meet these standard requirements, ensuring your photos will be accepted for official use.

DPI (Dots Per Inch) determines the resolution and print quality of your image. For digital use, 72 DPI is typically sufficient, but for printed documents like passports, 300 DPI is the standard recommended resolution. Higher DPI values result in better print quality but larger file sizes. Tweetkar tool allows you to select from common DPI presets or set a custom value to meet specific requirements.

Tweetkar tool uses advanced algorithms to minimize quality loss during resizing. When you select the “Auto Resize” option, we maintain the original aspect ratio to prevent distortion. The compression quality slider allows you to balance between file size and image clarity. For optimal results, we recommend starting with high-quality source images and using Tweetkar default settings, which are optimized for official document photos.

Absolutely! Privacy and security are Tweetkar top priorities. All image processing happens directly in your browser using JavaScript – we never upload your images to any external servers. This means your photos never leave your device, ensuring complete confidentiality. We don’t store, collect, or have access to any of your images or personal information. Once you close the browser tab, all processed data is permanently removed from your device’s memory.

Tweetkar tool supports all common image formats including JPG/JPEG, PNG, GIF, WebP, and BMP. You can upload images in any of these formats, and the resized images will be saved in high-quality JPEG format, which is the standard for most official document photos. This ensures compatibility with virtually all systems and applications while maintaining excellent image quality and reasonable file sizes.
