compress_pdf
Compress a PDF file to reduce its size. Renders pages and re-encodes as JPEG, iterating quality/resolution to hit a target size. Use this when a user wants to shrink a PDF (e.g. to 500KB, 1MB, or "smaller"). Free anonymous tier: 20 calls/day per IP, files up to 10MB. For larger files (up to 100MB) o
optimize_pdf
Lossless PDF optimization: garbage collection, stream re-compression. No quality loss. Good for PDFs with redundant data; effect is small on already-optimized files. Free anonymous tier: 20 calls/day per IP, files up to 10MB. Larger files / more calls need an API key (https://ko-fi.com/yugutou/shop)
inspect_pdf
Inspect a PDF: page count, file size, password protection. Use before deciding how to process a PDF. Free anonymous tier: 20 calls/day per IP. More calls need an API key (https://ko-fi.com/yugutou/shop).
