Choose a PDF: the tool shrinks the scans and photos inside step by step until the file is under 100 KB, keeping them as clear as the limit allows. Text stays text, and you see the size before you download.
Works in your browser: what you type or choose stays on your device and is not uploaded anywhere.

Questions
Will a scan still be readable at 100 KB?
A one-page scan usually is. Many pages in 100 KB get blurry: if the form allows, upload pages separately or choose 200 KB.
The tool says 100 KB is too small. What now?
The PDF has too many pages or large photos. Remove pages you don't need, or scan at a lower resolution, then try again.
