Tips for best results

• For text-heavy scans, save at higher resolution (300 DPI) and consider OCR later.
• For smaller file size, choose moderate compression or reduce image dimensions before converting.
• Use batch mode to merge images into a single PDF in the desired order.
• For HEIC images, convert to JPG if a tool lacks HEIC support.

Troubleshooting

• If orientation is wrong, rotate images in the app before exporting.
• If colors look off, check color profiles or export from the original app that preserves color.
• If file is too large, downsample images or use compression options.
