Questions
Can every PDF be compressed a lot?
No. Text PDFs compress more predictably than scanned or image-heavy PDFs. ToolMia shows the resulting file size so you can decide whether it works.
Will compression reduce quality?
Sometimes. Stronger compression can reduce image quality. The result shows the before and after size so you can decide whether it is acceptable.
What should I do if the PDF is still too large?
Try splitting the PDF or reducing image size before creating the PDF.
