Flexible Image Compression for Every Need

Optimize your profile photo for German university enrolment portals. Quickly resize your image for your Studierendenausweis and digital Semesterticket apps.

Use Case

Crucial for incoming university students (Erstis) navigating German campus portals (like CampusNet, HISinOne, or Moodle) who need to upload a lightweight ID photo.

How It Works

Before the Wintersemester or Sommersemester begins, you must complete your Immatrikulation (enrolment) by uploading a photo for your official German Student ID card (Studierendenausweis). Many German universities use older, highly restrictive IT portals that cap image uploads at tiny sizes like 50KB or 100KB. Our campus ID photo resizer is designed specifically to help you bypass these frustrating limits. By lowering the maximum width to 500 pixels and applying a balanced 60% JPEG compression, your photo shrinks to a lightweight size that older university portals easily accept. Get your campus ID and your digital Semesterticket / Deutschlandticket processed faster without fighting with IT errors.

What You Get

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