How it helps
Reduce JPG, PNG or PDF to the KB limit shown on a form
This exact-KB document reducer is for the error messages students see on exam, admission and scholarship portals. Enter 20KB, 50KB, 100KB, 500KB or another limit, choose the image output format when relevant, and download the result without sending the original file to a conversion server.
Private local processing
The selected file is handled by code running in this browser. This page does not send the document to a conversion API. For sensitive IDs or certificates, use a personal device and delete unwanted downloads after the form is complete.
Questions
Common questions about this tool
Can I choose any target such as 30KB or 200KB?
Yes. Enter the maximum KB shown on the portal. The tool aims to stay below it while keeping the file readable.
Can I convert a photo to PDF while reducing it?
Yes. Choose PDF as the image output. One image becomes one PDF page. A PDF input stays PDF so all of its pages remain together.
Why might a file not reach an extremely small size?
Every format has overhead and readable pixels need space. For difficult limits, choose JPG or Strong compression and inspect the result before submitting.
