Why is my PDF too large to send on WhatsApp?
PDFs with scanned images, high-resolution graphics, or embedded fonts can be very large. Compression reduces these elements while keeping the document readable, making it much easier to share.
What if my PDF is still too large after compression?
Try splitting the PDF into smaller parts with our Split PDF tool, then compress each part individually. You can also flatten the PDF or remove unnecessary pages to reduce size further.
