PDF tools

Five synchronous PDF endpoints. Each takes multipart/form-data and returns the result in the response body — no key required (rate-limited per IP, see Rate limits). Files are processed in the cloud over an encrypted connection and auto-deleted right after.

Inputs are numbered parts: file_0, file_1, … (declared order is preserved). Per-file size caps apply; oversized uploads return 413.

POST /pdf/merge

Combine multiple PDFs into one ordered document. Up to 50 files.

curl -X POST https://bastosconvert.com/api/v1/pdf/merge \
  -F file_0=@chapter1.pdf \
  -F file_1=@chapter2.pdf \
  -F file_2=@appendix.pdf \
  -o merged.pdf

POST /pdf/split

Split one PDF into individual pages, returned as a single ZIP archive.

curl -X POST https://bastosconvert.com/api/v1/pdf/split \
  -F file_0=@report.pdf \
  -o pages.zip

POST /pdf/compress

Shrink a PDF losslessly — deflates content streams, drops unused objects and rebuilds the cross-reference table; fonts and images stay bit-for-bit identical.

curl -X POST https://bastosconvert.com/api/v1/pdf/compress \
  -F file_0=@large.pdf \
  -o small.pdf

POST /pdf/rotate

Rotate every page by an angle (degrees: 90, 180, 270).

curl -X POST https://bastosconvert.com/api/v1/pdf/rotate \
  -F file_0=@scan.pdf \
  -F angle=90 \
  -o rotated.pdf

POST /pdf/jpg_to_pdf

Pack one or more JPGs into a single PDF, one image per page.

curl -X POST https://bastosconvert.com/api/v1/pdf/jpg_to_pdf \
  -F file_0=@p1.jpg \
  -F file_1=@p2.jpg \
  -o photos.pdf
