Split PDF by File Size

Many Indian government portals, university admission systems, and corporate ticketing tools reject PDFs above 2 MB, 1 MB, or even 500 KB. Split by Size divides at natural page boundaries so each part complies without arbitrarily cutting a single page in half.

Siliph Split by Size calculates cumulative file weight in the browser-backed engine and groups consecutive pages until the next page would exceed your threshold. You download a ZIP of numbered parts ready to upload sequentially or attach to separate form fields.

Splitting by size is gentler than aggressive compression when a portal checks both per-file size and minimum readable resolution for ID scans. Each part remains a valid PDF with embedded fonts intact.

Encrypted transfers protect tax returns and medical imaging packets during splitting. Auto-deletion within two hours on the free plan reduces exposure, and splitting requires no signup.

If a single page alone exceeds the cap—common with high-resolution maps—run Compress PDF on that page first, then split again; or use Extract Pages to isolate the heavy sheet.

Siliph split tools divide PDFs by range, bookmark, size, or text trigger entirely in the browser with encrypted transfers at each step. Generated parts are auto-deleted within two hours on the free plan, and splitting starts immediately without signup.
