How to Resize Images for University Admission Portals

Updated September 23, 2026 · 7 min read

Resizing is the single biggest lever for file size. Admission systems handle thousands of uploads and often set modest file limits for photos and supporting scans.

Recommended settings for university admission portals

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 800 px on the long edge
Quality70
File size100 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

How to Resize Images

File size scales roughly with the number of pixels. Shrinking a 4000 by 3000 photo to 800 pixels wide removes most of the data before compression even begins.

Keep the aspect ratio locked so nothing looks stretched. Our compressor scales proportionally when you set a maximum width, so you only need to enter one number: 800.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 100 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 800 and the target size to 100 KB.
  4. Press Compress, check the result and download it.

Wrapping up
