Easy ways to reduce PDF size and share large documents on WhatsApp
Sending documents via WhatsApp is one of the easiest methods of exchanging documents with friends, relatives, clients, colleagues, and customers.
It is possible to send any documents including PDF files, presentations, photos, spreadsheets, etc.
However, there may be cases where your PDF file is too big to send, takes too long to upload, and consumes too much space.
In that case, how would you send a large PDF file via WhatsApp?
One of the best solutions to that problem is to compress your PDF file. You can also divide your large PDF file into smaller files if you want to send selected pages.
It is possible to compress, split, merge, convert and manage any PDF files using AziPDF online service right in your web browser.
Why is my PDF too large to send?
PDF files can become surprisingly large when they contain:
- •High-resolution images
- •Scanned documents
- •Multiple photographs
- •Large graphics
- •Embedded fonts
- •Many pages
- •Presentation slides or other complex content
For instance, a normal text file may just take up a few hundred kilobytes, but the scanning of a 100-page file with pictures in it will result in a file of hundreds of megabytes.
A large PDF is difficult to transfer and distribute, particularly if you are working on limited mobile data or limited storage capacity.
This is why compression of the PDF file before transmitting it makes its distribution much easier.
What is the easiest way to send a large PDF on WhatsApp?
There are a number of methods available for the transfer of a huge PDF file.
You can:
- Compressing the PDF to make it smaller.
- Split the PDF file to create smaller documents.
- Uploading the file on a cloud server and sharing the link.
- Optimizing the document prior to sharing.
For most PDF files, compressing the file is the easiest way.
If all pages are not required, dividing the PDF file becomes even easier.
Method 1: Compress a large PDF before sending it
If you want to send the complete PDF, compressing it is usually the easiest solution.
A PDF compressor reduces unnecessary file data while trying to maintain good visual quality.

Method 2: Split a large PDF into smaller files
Sometimes you don't actually need to send the entire document.
For example, imagine you have a 100-page PDF but only need to send pages 20–30 to someone.
Instead of sending the complete document, you can extract the pages you need and share a much smaller file.
How to split a PDF with AziPDF
Step 1: Open the Split PDF tool
Go to AziPDF's Split PDF tool.

This method is particularly useful for invoices, reports, contracts, study materials, books, and other long documents.
Method 3: Compress the PDF after removing unnecessary pages
You can also combine both methods when your PDF is particularly large.
First, remove pages you don't need. Then compress the remaining PDF.
For example:
Original PDF → Remove unnecessary pages → Compress PDF → Send on WhatsApp
This can significantly reduce the amount of data you need to share.
Method 4: Merge multiple PDFs before sending them
what if you have several small PDFs rather than just one big PDF?
Having to send each one separately can be difficult to manage.
However, you could simply join them all into one PDF.
