Compress PDF to 50 KB
50 KB is a very tight limit. It works best for a single page, and the result needs checking before you submit it.

What to expect at 50 KB
A single scanned page can usually be brought under 50 KB, but it will be noticeably softer. Small print and faint stamps may become hard to read, so always open the result and zoom in.
Several scanned pages rarely fit at a readable quality. Upload only the page the form asks for, or split the document first.
Text-only PDFs (not scans) are often well under 50 KB already.
Frequently asked questions
Is 50 KB enough for a scanned document?
For one page, usually, though it will look softer. For several pages, it's very hard to keep text readable at 50 KB.
How do I make a PDF smaller?
Drop the PDF in. Quikdo re-saves the pictures inside it at a lower resolution and quality, which is where most of the size is. Pick a target like 200 KB if a portal has a limit.
How do I get a PDF under 200 KB?
Choose the 200 KB target before you drop the file in. Quality is lowered only as far as needed to get under it.
How do I convert a PDF from MB to KB?
Set a target in KB, such as 500 KB or 200 KB, and compress. A 3 MB scan often ends up a few hundred kilobytes.
