Frequently asked questions

How much can I reduce a PDF's size?

Compression results vary depending on the original content. PDFs with many images can be reduced by 50 to 80 percent. Text-only PDFs are already compact and compress less.

Will image quality be affected?

Light compression preserves quality well. Aggressive compression reduces image resolution noticeably — choose based on your needs.

Is there a file size limit?

Files up to 200 MB are supported, which covers virtually all everyday documents. Larger files may take a bit longer to process.

Can I compress a PDF that already has been compressed?

Yes, but gains will be minimal since most redundancy has already been removed.
