PDF compression is completely safe. Only the file size changes — all content, formatting, and functionality remain identical. No data is lost or altered in the visible document.

How much can a PDF be compressed?
Typically 30-70% depending on image content. PDFs with many photos compress more than text-only documents.
Will my PDF look the same after compression?
Yes. Text and layout remain perfect. Only image quality may be slightly reduced if you choose aggressive compression.
Is there a file size limit?
You can upload PDFs up to 100MB for compression. The tool runs in your browser, so very large files may take longer to process.
