Yes! Files are processed on our server and automatically deleted after 30 minutes. We don't store or analyze your documents.
How large files can I compress?
Maximum file size is 100MB per file. You can upload up to 10 files at once.
How much space can I save?
Typical compression is 50-90% size reduction. Files with many images give the best results. Already optimized files may not shrink significantly.
Does compression affect document quality?
We use Ghostscript's 'ebook' mode which is visually lossless. Images are optimized to 150 DPI - perfect for screen viewing and home printing.
What PDF files are supported?
We support all standard PDF files. Encrypted or password-protected files must be unlocked before compression.
