How to Use

Upload — Click or drag PDF/images to the dashed zone. Multi-file and large files (<100MB per batch recommended) are read locally only.
Configure & process — Set pages, angle, password or quality, then hit “Calculate / Process”. Split PDF by Size runs via WebAssembly and pdf-lib in your browser — no server queue.
Preview & download — Check pages, size and thumbnails on the right, then download. Batch jobs download one by one; tweak and re-run if needed.

Tips & Notes

Page syntax: Use 1,3,5-7 or 1-10,15; empty means all. Out-of-range pages are ignored.
Privacy & size: Everything runs locally — no server upload. For large files, process in batches of 50–100 pages.
Fidelity: Fonts and vectors are preserved where possible. For scanned PDFs, run OCR/searchable PDF first, then convert.
