Flexible Image Compression for Every Need

Instantly compress your passport photo and scanned IDs for the German uni-assist portal. Avoid upload errors and ensure your university application is processed on time.

Use Case

Crucial for international students applying to German universities via uni-assist who need to shrink heavy document scans or profile photos to meet strict portal limits.

How It Works

Applying to universities in Germany through uni-assist can be a highly stressful process, and missing a deadline because of a 'File Size Exceeds Limit' error is a nightmare. The uni-assist portal requires clear, legible uploads of your passport photo and ID documents, but it frequently rejects the heavy, high-resolution photos taken by modern smartphones. Our specialized uni-assist compressor is built to solve this. By intelligently reducing your image width to 800 pixels and applying a balanced 60% JPEG quality, we shrink your multi-megabyte files into lightweight, portal-friendly kilobytes. Your text remains crystal clear for the admissions team to verify, and because processing happens locally in your browser, your sensitive passport data never leaves your device.

What You Get

Optimized images that balance quality and file size for faster uploads.
