FAQ
How do I combine phone scan images into one PDF?
Select the page photos together, choose a cleanup mode, and build the PDF. Each image becomes one page.
What does high-contrast scan mode change?
It converts pixels to grayscale and increases contrast, which can make dark text on light paper easier to read.
Does this tool automatically crop document edges?
No. Crop and straighten photos before upload; this version fits the complete image onto each page.
Can I scan both JPG and PNG pages in one PDF?
Yes. JPG, PNG, and WebP images can be mixed in a single batch.
Will Scan Images to PDF run OCR?
No. The output contains page images and does not add a searchable text layer.
