Where you need a PDF under 100KB
- Job and exam application forms that allow only 100KB for certificates or ID proof
- Government and scholarship portals with strict upload limits
- Mark sheets, Aadhaar, PAN, ID cards and other one-page documents
- College admission portals
100KB is small, so it works best for 1 to 3 pages. A one-page certificate usually fits easily and still looks clear. For a long document, first remove pages you don’t need with Split a PDF, or turn on Black & white — scanned pages become much smaller and often look cleaner too.
How to reduce PDF size
Questions people ask
How do I compress a PDF to 100KB?
Choose your PDF above. 100KB is already selected, so just press “Make my PDF smaller”. We try the clearest settings first and keep the best result that fits under 100KB.
My PDF still won’t go under 100KB. What can I do?
Turn on “Black & white”, or remove extra pages first. A PDF with many photos or pages may need a bigger limit, like 200KB.
Will the text still be readable?
For 1–3 pages, yes. We show you a preview and the new size before you download, so you can check it first.
Is it safe for my documents?
Yes. Your PDF is processed inside your own browser and is never uploaded to any server.
