FAQ
Why is my PDF over 25MB?
PDFs with many high-resolution images, embedded fonts, or scanned pages tend to be very large. Compression optimizes these elements.
Will the recipient see any difference?
With light to medium compression, the PDF looks virtually identical. Only aggressive compression may slightly affect image clarity.
