Exam Guidelines Compliance

Resize and Compress Photos for Visas and Exam Portals

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 locally in your browser.
