Compress PDF FAQ
Is PDF compression safe for sensitive data?
Absolutely. Docify uses 256-bit encryption for all file transfers and your documents are automatically deleted after 30 minutes.
Does compression change my layouts?
No. Our compression only targets redundant data and image resolutions. Your text formatting and layouts remain identical.
Can I compress a PDF multiple times?
Yes! You can use our 'Compress More' feature to further reduce size, though note that quality may degrade with repeated extreme compression.
Is there a limit on file size?
We support files up to 100MB for free online compression. For larger files, please split them before compressing.
