Technical note

SID to PDF: what to expect from the conversion

PDF is a page format, so each SID image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as PDF opens on any computer and any phone. reaConverter produces those from SID in batch, entirely offline.

  • Render every file in a folder to PDF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Our law firm deals with hundreds of scanned documents daily. reaConverter's OCR feature turns them into searchable PDFs, and the batch conversion saves us days of manual work. The output is flawless – even with old, low-quality scans. This is the best investment we've made for our document management.

FAQ

SID to PDF Conversion
