Frequently asked questions

Can every PDF fit in 50KB?

No — multi-page colour scans usually can't. Single-page text PDFs and signature pages typically can.

Why is mine still over 50KB?

Embedded images are the main culprit. Try splitting the PDF and compressing each page separately, or convert images to grayscale first.

Will text remain readable?

Yes — text is left as vector. Image quality is what gets reduced.
