After entering the Speedpdf page, you can see all PDF functions in the middle, including PDF to Word, Excel, PPT, PPT, JPG (or vice versa), PDF merging, PDF splitting, PDF encryption and decryption, PDF compression, etc. Click on the function you want to use, and you can use it without registering.

In addition to PDF, if you have JPG image compression needs, this one is also available, but it also has a limit on the number of times, which is a little more troublesome:
