How to Reduce PDF File Size Under 100KB – Fast & Free
Shrink your PDF files to under 100KB instantly. Use 24x7 PDF Converter to compress PDFs online – fast, secure, and completely free
Ever been blocked from uploading a file because it’s “too big”? Whether you’re applying for a visa, submitting documents on a government site, or attaching a file to an email, strict size limits can be a major roadblock. If you need your PDF to be under 100KB, you’re in the right place.
With 24x7 PDF Converter, shrinking your file is simple — thanks to our smart Split by Size tool.
Why File Size Limits Matter
Many portals, especially older or official ones, still cap uploads at 100KB. That’s tiny by modern standards — but there’s a smart way around it.
Our Split by Size feature gives you precise control over your PDF file size. Just set your size limit (e.g., 100KB), and let our tool break the file down into perfectly sized chunks — all while keeping your content intact.

Why You May Need This Tool:
🛂 Visa & Immigration Applications
Many embassies enforce strict limits — uploading even a few kilobytes over can delay your process.
🏛️ Government & Legal Portals
Still operating on outdated systems, these portals often max out at 100KB per file. Submitting court forms or ID documents? You’ll need to shrink them.
📩 Email & Older Platforms
Some email providers or legacy websites bounce attachments above a certain size — usually without warning.
Why Not Just Compress?
Compression is great — but only up to a point. If your file has images, scans, or signatures, excessive compression can ruin clarity. Worse, it might not get the file small enough.
That’s where Split by Size shines:
-
🔍 Precise control over file output size
-
✨ Zero loss in quality
-
📄 Each part looks just like the original — only smaller
-
🎯 Meet exact size limits without guessing
Tips for Best Results
-
📚 Works best with multi-page PDFs

🖼️ If your file has images, consider compressing first, then split
-
📑 Always preview your output to ensure it contains what you need
-
🚫 For 1-2 page PDFs, compression might be a better first step
