The .pdf format is ideal for accurate transfer of textual information, including formatting and other elements. Another obvious plus to PDF is document protection with a password. But there is one drawback – sometimes files with a weight of 200 KB in transfer to this format expand to 1.2 MB, and this is not always convenient when transferring.

How well does the Quartz filter compress the image? In the test example, a file with scans of pages in A4 format with a size of 6 MB was compressed to 800 kb (with inevitable, but not fatal, quality losses). In general, the degree of compression here depends on the source – if it was a document converted from Word to PDF, its size will decrease 10 times.

Conclusion

If the quality of the image obtained after filtering does not suit you, there is a sense of a more powerful PDF editor, such as PDF Expert, which, among other things, has tools for compressing the file. But, again, in general, for most operations of this kind, the Quartz filter is quite enough.
