Step-by-Step: From Upload to Verified Download

1. Prepare: Export with Embed fonts off, PDF/A off. If scanned, Crop PDF white borders.
2. Upload to API Docs: drag & drop, up to 100MB.
3. Settings: pick exact target or level; for signatures keep 150 DPI, for plain text 72 DPI is fine.
4. Process: click Process — iterative binary search hits target in 3–4 passes.
5. Verify: zoom 150%, check Properties ≤ target, test print one page.
6. Chain: Delete Pages → Merge PDF → compress — order matters.

Advanced Tips: Edge Cases, Batch & API

Bulk needs filename preservation, verification and failure handling. ToolsLead web batch handles 50 files — drag all, set one target (e.g., 200KB), process, download ZIP with original names + _compressed.pdf suffix. For larger, use API: POST /v1/pdf/compress with targetSize via API Docs, retry on 413, verify via GET /v1/jobs/{id}.

Zapier: Folder new file → compress → email. n8n: webhook → compress → Drive. Check logs for Processed locally badge to keep sensitive bulk on device.
