Compress a PDF to 100 KB
PDF Desk lowers the resolution step by step until the file is under 100 KB.
Files stay on this device. Nothing is uploaded.
How many pages fit in 100 KB?
At readable quality, 100 KB holds 1–3 scanned pages in black and white, or a few pages of plain text. Photos and colour backgrounds take more space than plain text.

Questions
Are my PDFs uploaded?
No. PDF Desk opens and writes the file with JavaScript inside your browser tab. Nothing is sent to a server, so it is safe for contracts, IDs and bank statements.
My PDF will not go under 100 KB. What can I do?
Choose black and white, split the PDF into parts with Split PDF, or remove pages you do not need with Delete pages.
Will the PDF still be readable?
Normal text stays readable down to about 60 DPI. Small print and fine drawings need higher limits.
