FAQ
How to resize image to specific KB?
Select "File Size" mode, enter target size (e.g., 100KB), and click Resize. The tool automatically adjusts image quality to match your target file size. Use presets for common sizes like 50KB, 100KB, 200KB, or 1MB.
How to resize image without losing quality?
Use "Pixels" mode with "Lock aspect ratio" enabled. This preserves proportions and prevents distortion. For best quality, always reduce from larger to smaller dimensions. Enlarging may reduce quality.
Can I resize to exact 20KB for passport?
Yes! Select "File Size" mode, choose 20KB preset (or enter 20 in KB field), and click Resize. The tool will find the optimal quality setting to achieve approximately 20KB file size.
