Why does “reduce pdf file size” sometimes barely change file size?

Vector text PDFs compress well; full-page photo scans may already be near their limit. Run one pass, compare MB and readability at 100% zoom, then stop.

Is online PDF compression safe for contracts?

Keep an uncompressed archive for audit. Use LovePDF Compress PDF (/ja/tools/compress-pdf) for the outbound copy only after you verify signatures and tables.

Should I merge before compressing?

Run one pass, compare MB and readability, then decide whether to split chapters instead of chasing extreme ratios.

High-demand workflow notes

Because “reduce pdf file size” carries strong search volume, teams often standardize this step in written SOPs. Document who uploads, who verifies page order, and where the authoritative PDF is stored after download.

If your portal caps attachment size, plan compress or split as a second pass instead of five blind compression attempts on scans.
