Other things to consider

 

Smallpdf always tries to maintain a high quality of the file content after you use your file compression. Because of this, we do not offer the option to choose the compression rate at the moment, to preserve the quality of the output file. In the unfortunate case where the size of a PDF is still large than the capped limitations of your email service, you can try to drag it back into our tool, and we will try to compress it harder. Keep in mind that this process could impede the quality of your file, with every passing compression.

The largest PDF that our compression tool can accept is 5GB. If you have a file larger than this, we’d suggest you split it into smaller files before using our tool to compress your PDF online.

Other than splitting and how to compress a PDF for emailing, there are 17+ other useful tools that we have also created over the years, to aid you with your digital document process. Check out how to:
