Why Merge CR3 to PDF?
CR3 is Canon's current RAW photo format used by all modern Canon cameras — EOS R series (R5, R6, R7, R8, R10), EOS 90D, and PowerShot G7 X III. CR3 uses the ISO Base Media File Format (ISOBMFF) container with Canon's lossless or lossy compression. Merging CR3 files to PDF creates a shareable document from your Canon photos — ideal for client proofs, wedding contact sheets, or portfolios.
Each CR3 file is rendered and placed as one page in the combined PDF.
