Usually, we also do some documents to upload, but some platforms will remind us that the upload failed when uploading. This is because the file is too large. In this case, how do we compress the file?

1, open the pdf compression tool and click the pdf compression function on the page (fast pdf compression software), and we can add files.

2. Find the location of the pdf file, click the file to move to the compressed page, click "Select File" in the tool to find the location of the pdf file and open it.

3. After opening the file, click the compressed item on the selection page, and select the item we need to compress for compression.

4. Then click the "Start Compression" button on the page to compress the pdf file.
