In case you need to reduce your file's size, no matter if it's for sending it out via email or just to save some space, Documents lets you optimize PDF files - you can select the desired quality and even see the size of the future file.
Note: This feature works only for the files saved locally. To reduce the size of the files saved on the cloud please save them locally first. It's not possible to undo the process.
How to reduce the file's size
- Open your file.
- Tap More ... at the top right.
- Select Reduce File Size.
- Choose the needed quality: Lossless, High, Medium, or Low. If you have some images that need to preserve the quality, you can use the Lossless option.
- Tap Reduce.
Note: Some files can't be reduced - for instance, files that do not contain any images or were created with vector graphics.
Tip: There is an alternative method for reducing the file's size in case you don't want to reduce it drastically - for this, you can create a ZIP archive of the file if you use the Compress option.
