Why Won't a Text-Only PDF Get Much Smaller?
Direct answer
Text instructions are compact, so an image-focused compressor may have little to reduce. Fonts, forms, attachments, or structural data can dominate the file instead of page text.
Why this happens
A page of vector text can require far fewer bytes than one photograph. Re-encoding images therefore produces little benefit when the PDF contains no meaningful image streams.
Font programs can be the largest component in a text document, particularly with several languages, weights, or duplicated subsets. Interactive forms and attachments can also contribute size.
Avoid rasterizing the text to force a smaller file. That can harm search, accessibility, copy/paste behavior, and quality at zoom.
Better options
- Export cleanly from the source application with font subsetting.
- Remove unnecessary attachments through an approved PDF editor.
- Keep vector text rather than printing pages to images.
- Accept the original size when further reduction would damage function.
