Plan the PDF Before Combining Images
Image-to-PDF conversion places raster images onto document pages. It is useful for scanned receipts, forms, photographed notes, evidence packets, and screenshots, but the source image quality sets the ceiling for readability.
Decide the page order, orientation, page size, margins, and whether images belong in one PDF or separate files. Rotate camera photos and remove duplicates before conversion.

Match Image Sources to PDF Page Settings
| Image source | Preparation | PDF check |
|---|---|---|
| Scanned documents | Deskew, crop borders, and confirm contrast | Text readability and consistent page size |
| Phone photos | Correct rotation and perspective | Shadows, glare, and clipped corners |
| Screenshots | Remove private UI and irrelevant areas | Pixel dimensions and text sharpness |
| Mixed portrait and landscape images | Choose whether to rotate or preserve orientation | Page consistency and viewing comfort |
| High-resolution photos | Keep originals and consider output size | Image detail versus PDF file size |

Fix Common Conversion Problems
| Problem | Likely cause | Practical check |
|---|---|---|
| Pages are in the wrong order | Files were sorted lexically rather than numerically | Rename with zero-padded numbers before adding |
| Some pages are sideways | EXIF orientation was not interpreted consistently | Rotate source copies explicitly |
| Text is hard to read | The photo is blurred, skewed, dark, or compressed | Rescan or rephotograph before conversion |
| The PDF is very large | Many high-resolution images were embedded | Use suitable image dimensions and compression for the destination |
| Search finds no text | The PDF contains page images only | Run OCR and verify recognition when searchable text is required |
Image to PDF Converter FAQ
Can I combine multiple JPG and PNG files into one PDF?
Yes. Add supported images, arrange them in the intended order, convert, and inspect the full PDF before deleting or moving the sources.
Why are PDF pages sideways?
Camera orientation metadata may be interpreted differently. Rotate prepared copies explicitly before conversion and verify portrait and landscape pages.
Will text in the images become searchable?
Not through image placement alone. Use OCR to create recognized text, then proofread names, numbers, and punctuation.
How can I reduce the PDF file size?
Use image dimensions and compression appropriate for the destination. Keep higher-quality originals separately because aggressive compression cannot be reversed.
Should I delete the source images after conversion?
No, not immediately. Keep the original images until the PDF has been reviewed, backed up, and accepted for its intended use.
