关于Form Recognizer支持PBM文件及转TIF格式的技术问询

Hey Michael, thanks for reaching out with this question! Let's cover both parts of what you're asking:

Azure Form Recognizer PBM File Support #

Right now, the official Form Recognizer documentation doesn't list PBM (Portable Bitmap Image) as a supported file type. As for whether it'll be added in the future, Microsoft typically evaluates new format support based on user demand and real-world use cases. Your best bet to push this forward is to submit a feature request through Azure's built-in feedback channels (like the feedback option in the Azure Portal) — the product team actively reviews these requests to prioritize updates. That said, there's no public timeline for when PBM might be added to the supported list.

Easy Ways to Convert PBM to TIF #

If you need a workaround right now, there are plenty of simple tools (both GUI and command-line) to handle this conversion quickly:

GUI Tools #

• GIMP: This free, open-source image editor makes conversion straightforward. Just open your PBM file, go to File > Export As, select TIFF as the output format, and adjust any compression settings you need before exporting.
• IrfanView: A lightweight, fast image viewer that supports batch conversion. Open the app, go to File > Batch Conversion/Rename, add all your PBM files, set the output format to TIF, and hit start to process them all at once.

Command-Line (For Automation/Batch Jobs) #

If you need to automate the process or handle large batches, ImageMagick is a great cross-platform option. Once installed, you can convert a single file with:
convert input.pbm output.tif
For all PBM files in a directory:
convert *.pbm -format tif %d.tif
