How to compress your file to 20KB

Most online application portals, including US Visa / DV Lottery, Schengen Visa, UPSC, and SSC, specify strict file size ranges (e.g. under 240KB, 50KB, or 20KB) and precise dimensions (e.g. 600x600 pixels or 3.5x4.5 cm). Our Resize Photo tool lets you select standard presets, crop to the correct aspect ratio, adjust image dimensions, and compress files iteratively to meet these global standards securely. Large files can cause upload failures on strict portals or delay email delivery. Our advanced local processing engine ensures your file is shrunk to exactly 20KB.
