Size Converter
Convert numeric sizes between pixels, inches, feet, millimeters, centimeters and meters. Use DPI/PPI when converting between pixels and physical units.
ℹ️ About Image Resizer
Image Resizer changes a photo to an exact pixel size using ready-made presets for social media (Instagram, Facebook, TikTok, LinkedIn and more), printing (A4) and ID-style photos (passport and CNIC/NADRA format), or a fully custom width and height. The entire image is resized to your chosen dimensions. Keep aspect ratio enabled to prevent stretching; turn it off only when an exact non-proportional size is required.
🛠️ How to Use Image Resizer
Upload your photo, choose a preset or enter a custom width and height, decide whether to keep the original proportions, and click "Resize & Download". The full image is resized to the target dimensions without cropping.
📌 Tips for Size Converter
Convert common digital and physical size units such as pixels, inches, feet, millimeters, and centimeters. This is useful when preparing images for print, web layouts, documents, or design specifications where the same measurement may be expressed in different units.
Remember that pixels describe digital dimensions, while inches, feet, millimeters, and centimeters describe physical measurements. Converting between pixels and physical units requires a resolution such as DPI or PPI; without that information, a pixel-to-print conversion cannot represent a single universal physical size.
