Conclusion On Email attachment size -sometime email attachments looks larger than the original size here i am providing the points how it is possible on the emailed document.
sometime ago i want to send an email which has a large size picture but i was not been able to send email the reason i am thinking is about because the file is large but i know that the file is in the below of the limit of the size of the attachment given by email provider. Can i get the exact reason why it happen to me?
Email attachment size
Here are some of the reasons which is responsible for making the size of attached file larger then the original file size.
- Packet Switching
- Binary form of file
Now We will take a look on those two reasons one by one.
Email attachments size increase because of packet switching
Packet Switching Is the technique at which transfer of data travel from one source node (computer or particular IP address) to the another destination node. When we use packet switching technique to transfer data from one source to another destination then data of file divide into the shorter form of packet and for arranging those data at the destination node source node at the time of transfer put some headers into the packets of data which make the attached file more larger then the original size of the file.
Now a days packet switching techniques used on various transfer mode of data from source node to destination node.
Here are some of the fields which used packet switching as primary technique for transferring data from one source to another.
- Email attachments
- TCP data transfer
- FTP data transfer
Email attachments size increase because of Binary form of file
As we know that data transfer on internet as a binary form. So there are some encoding techniques have been used to send any format attachments over the internet. If we are sending any attachments of jpg image then one of jpg file will look on binary form much like given below row data.

It may not be possible to arrange those files as same as it has been arranged on the source end at the time of sending the attachments, If the particular destination node decrypt the attachments with another format like it has to decrypt with 32 bit format but because the destination operating system and the processor using 64 bit format to decrypt the data then file size will increase automatically than the original file size.
