About This Tool
What is Compress PDF to 100KB? It is a free browser-based tool that shrinks PDF files to 100KB or less while keeping text crisp and readable. Job applications, government forms, and scholarship portals commonly enforce a 100KB ceiling on uploads.
Generic PDF compressors leave you guessing. This tool is tuned for the 100KB target, so you can upload a resume, certificate, or signed document and hit the limit on the first attempt — every time.
How It Works
Three simple steps to get your optimized PDF.
Upload Your PDF
Select the PDF you need to shrink. Files are processed locally in your browser — never uploaded to a server.
Set the Compression Level
Use High compression for the smallest file, or Medium for a balance of size and image quality. Retry until the result reads under 100KB.
Download Under 100KB
Save your compressed PDF and upload it anywhere. The file will be under 100KB and ready to go.

Frequently Asked Questions
Can a scanned PDF really go under 100KB?
Yes. Image-heavy scans compress dramatically. For text documents, 100KB is easy. Use High compression for scanned pages and Medium for text-heavy files.
Will my text be readable at 100KB?
Absolutely. PDF text is vector-based, so it stays sharp at any size. Compression mostly affects embedded images, not readability.
Is there a limit on how many PDFs I can compress?
No. Compress as many PDFs as you need, as often as you need, completely free.
