How much room each page gets
100 KB is about 100,000 bytes for the whole file. Spread over three pages that is roughly 33 KB per page; over ten pages, about 10 KB each, which is too little for a readable scan. That is why this target suits one to three pages.
Prepare the file first
- Keep only the pages the form asks for. Split PDF can pull them out.
- Crop away empty margins and desk or table around a photographed page before making the PDF.
- A scan of a printed page compresses far better than a phone photo of it.
What the tool does to reach it
It redraws each page at lower and lower quality and keeps the first result under 100 KB, starting from the sharpest. Text becomes part of the picture, so it can no longer be selected. Keep your original.
If it stays above 100 KB
You get the smallest file it could make and its size. Remove a page, or ask whether the portal accepts a limit of 200 KB or more, which keeps text clearly readable.
