Troubleshooting

Common issues and how to fix them.

No files found in folder

Make sure the folder contains supported files: .md, .txt, .docx, .jpg, .jpeg, .png, .webp, or .gif
Files inside subfolders are not included — only files directly in the selected folder
Check that files have the correct extension and are not hidden

Conversion fails for a specific file

Try opening the file in another app to confirm it is not corrupted
For markdown files, very unusual syntax or deeply nested structures may not render correctly — simplify the file and retry
For images, confirm the file is not truncated or in an unsupported variant (e.g. CMYK JPEG)
The app logs each file’s result in the conversion log — check there for the specific error

Combined PDF is in the wrong order

Files merge in alphabetical filename order. If the order is wrong:

Add numeric prefixes to filenames: 01_intro.md, 02_chapter.md
Use zero-padded numbers to ensure correct sort: 01, 02, 10 rather than 1, 2, 10

Images appear too small or blurry

The app scales images to fit the page width at screen resolution
For sharper output, use higher-resolution source images (at least 150 dpi at the final print size)
Try switching to Full page mode in Auto-pair settings if the image is being constrained by inline flow

Emoji or multilingual text looks wrong

Keep Windows and the Microsoft Edge WebView2 Runtime up to date
Batch Text to PDF bundles its emoji font; no separate emoji-font download is required
If a specific writing system or emoji sequence is still missing, send the exact text and the generated PDF to support

Output folder not found

The output subfolder is created automatically inside your input folder — you do not need to create it first
If you changed the subfolder name to an absolute path, change it back to a simple name like pdf
Check that you have write permission to the input folder

App won’t start or crashes on launch

Check that Windows is up to date; the app requires Windows 10 or later
Reinstall the app from the Microsoft Store if the issue persists
