How to Reduce PDF Size to 100KB for Application Forms

Updated 2026-02-18Verified Private

Many online portals and government application systems limit PDF uploads to 100KB or less. This can be frustrating when your scanned document is several megabytes. This guide shows you how to hit that 100KB target using Tulz.

Why is this needed?

Application portals use these limits to save server space. However, standard 'Save as PDF' from Word or Scanners creates unoptimized files that are much larger than necessary.

!Step-by-Step Instructions

1

Upload your PDF to Tulz

Go to our [PDF Compressor](/tools/pdf-compress) and drag your file into the blue box. We support files up to 50MB.

2

Select 'Strong' Compression

To reach 100KB, you'll likely need the 'Strong' compression setting. This uses advanced algorithms to strip unnecessary metadata and optimize images.

3

Download and Verify

Click compress and download the result. Our tool will show you exactly how much size was reduced before you download.

Pro Tips

  • If the file is still over 100KB, try converting it to Grayscale first.
  • Scanned documents are always larger than 'digital' PDFs. Try to use digital exports when possible.

Frequently Asked Questions

Will my PDF look blurry?

Our compression algorithm prioritizes text clarity. While images might see a slight reduction in quality, the document remains perfectly readable for official use.

Is it safe to upload my ID or passport?

Yes. Tulz processes everything in temporary memory. Your files are never saved on our disks and are deleted instantly after you finish.
