IMAGE PDF SETTINGS
Choose settings that match the output
Use DPI and page size together. Decide whether you want an image-sized page or a standard sheet, then check the preview and export.
Set DPI and page size
Use Auto when physical size should follow the selected DPI, or choose A4/A5/Letter/Legal for a fixed page. Adjust orientation and margins.
Create and inspect
Export the PDF and check the result at the intended physical size. A higher DPI cannot restore detail absent from the source image.
DPI & PRINT SIZING
Set DPI and page sizing for an image PDF
A good print PDF depends on both the source image's pixel dimensions and the size at which it will be placed on a physical page. Pic2PDF offers DPI choices and fixed paper formats, but these settings solve different parts of the job: Auto page size uses DPI to calculate physical page dimensions, while A4, A5, Letter and Legal fix the page and fit the image inside it.
DPI is a sizing choice
With Auto page size, the selected DPI maps source pixels to a physical page dimension. A higher DPI makes that auto-sized page physically smaller for the same image.
Fixed paper formats
Choose A4, A5, Letter or Legal when the document must use a known sheet size. The image is fitted inside the page while keeping its aspect ratio.
Source pixels still matter
DPI cannot recreate detail missing from a small or blurry source. For print, begin with the largest and clearest original image available.
Check orientation and margins
Choose Auto, Portrait or Landscape and set margins to control the available image area on the page before exporting.
FAQ
Image PDF quality and DPI questions
Does 600 DPI make a low-resolution image sharper?
No. DPI does not invent source detail. When Auto page size is selected, it changes the physical dimensions calculated from the image's pixels; it does not increase those pixels.
What does Auto page size do?
Auto calculates the page dimensions from the source image's pixel width and height and the selected DPI. This can create a page with a different physical size for each image.
What if I need an A4 PDF?
Choose A4 as the page size. The page stays A4 and the image is fitted within it; orientation and margins control the available space.
Which DPI should I choose for printing?
It depends on the original pixel dimensions and the physical print size. Higher DPI is useful only when the source has enough pixels for the size you need; review those two values together rather than treating one DPI number as a quality guarantee.
