WeChat PDF is always doubled in size? My Transfer and Compression Tips

A strange phenomenon that bothers many people: a5MBright of privacyPDF, WeChat sends it out, the other party saves it as12MBor, conversely, receive aPDF, hand it over to a colleague"File too large to send". WeChat is the most commonly used transmission channel, yesPDFNot exactly friendly. After stepping on the pit many times, I summarized several practical experiences.

Understand the rules of WeChat first

WeChat has two hard limits on sending files: Normal chat file limit1GBOld version200MBHowever,When the original image mode is turned off, the image will be compressed, andPDFWill not be compressed. Another pit is that the WeChat transmission process itself will not changePDFVolume, so called"Volume doubled"ProbablyWhen the sender uses "file" and the receiver saves it as a new file, it is stored by the mobile phone storage mechanism orWPSCloud Sync Repackaging, or the original file with a large number of redundant objects. If you encounter an abnormal volume, right-click on the computer to see the original size, don't worry about WeChat.

Preparation for compression before transmission

WeChat phone is not built-inPDFCompression, My Practice by Device:

On your mobile phone：iOSUse the shortcut "CompressPDF"Processed and then sent (as detailed in the previous article); for AndroidWPSThe "CompressionPDF"function, select" Medium "file quality, the WeChat scene is fully adequate.

On your computer: Batch files are first pressed uniformly and then sent again. My customary parameter is150dpi+60%Quality, overwhelminglyPDFPressing is over10MBWithin, there is no pressure to go to WeChat.

ReceivesPDFCorrect posture for retransmission

ReceivesPDFWhen forwarding,Direct long press→ forward, WeChat transmits the original file, and it will not be inflated again. If you are afraid of "saving to your phone" and then sending it with a file manager, some Android file managers will be repackaged.iOSSave the user as before proceeding from FileAppShare sending, same size.

Extra largePDFAlternatives to

What if I finish pressing or exceed the limit? My three options:

1.       Split...with:WPSORSmallpdfGIVE!PDFSplit into upper and lower parts for splitting;

2.       Links: The file is placed on the network disk (Tencent Document, Microcloud), WeChat sends a link and extracts the code, and the other party is on its own;

3.       Convert to Format Contingency: The main content of the file, turned into a growth map to send, WeChat is friendly to the picture.

In a nutshell: WeChat is just a channel,PDFVolume management depends on the compression before sending. Cultivation"Compress before sending"muscle memory, much safer than rescuing afterwards.
