Step-by-step instructions (English)
- Select the images and arrange their page order.
- Choose A4, Letter, or Fit image, then set orientation, margins, and Fit or Fill.
- Generate the PDF and check framing and page order before downloading.
公式与方法
Each image becomes a page in the chosen order. A4 and Letter use standard page dimensions; Fit image sizes the page from the image at a 96-pixel-per-inch reference. Fit preserves all image content; Fill crops to the page margin rectangle.
实际示例
Choose A4 portrait and a 20-point margin for a simple photo document. Reorder the images before generating the PDF.
When this tool is useful
Create a single document from photographs, scans, or screenshots for convenient sharing. Standard page sizes suit printing; Fit image is useful when you want each page to follow the source image proportions.
Common mistakes and limitations
- This creates image-based PDF pages; it does not perform OCR or make photographed text searchable.
- Fill can crop image edges, so use Fit when every part of a receipt or document must remain visible.
Practical questions about this tool (English)
Does converting photos to PDF improve their readability?
No. The PDF contains the available image detail. Start with clear, adequately sized images and inspect small text after export.
Why are there margins around my image?
Margins reserve space between the page edge and the placed image. A mismatch between page and image proportions can add further unused space in Fit mode.
