What changes when I switch from A4 to Letter?
The PDF page dimensions change, not the original image pixels. Pick the paper standard your recipient or printer expects.
CHOOSING THE RIGHT PDF SETTINGS
Image to PDF Converter
A practical guide to the converter controls: shape your pages for printing, archiving, or sending before you create the file.
Choose images & startConverter
Your pictures are placed into the document as images; writing inside a photo remains part of that image.

Choose paper size for the destination
Start with where the PDF will be used, not only with the shape of the source picture. A4 and Letter are different paper standards; select the one a recipient or print service requests. A5 may suit a smaller reference, while Legal and custom dimensions serve less common layouts. When an image is wider than it is tall, compare landscape with portrait before settling on a page orientation.
The paper-size control changes the PDF page, not the pixel dimensions of the original file. The image is fitted inside the available page area. If its edges are important, leave enough margin to keep them clear on the page and inspect a finished sample before making a larger set.
Set margins and image quality separately
Margins change the white space surrounding an image; cropping changes which part of the source image remains. Use the crop frame to remove background clutter, then use margins to decide how the kept image sits on paper. A tighter margin can help a graphic fill the page, while additional white space can suit printed handouts and pages that will be bound.
Choose Compact, Balanced, or Best JPEG quality according to how much detail the final PDF must preserve. Smaller output may be useful for an email attachment, but it can soften text-like markings that are already inside an image. The estimated file size is a guide, not an exact promise; make a sample and inspect it at the size your recipient will use.
Add a cover and a clear download name
A group of images intended for a colleague or an archive benefits from a recognizable first page. Open the optional cover controls to add a title, subtitle, date, or a separate cover picture. The cover appears ahead of the image pages; it is not required for a quick one-picture PDF. Leave those fields collapsed when you only need the main document.
The output name can use a source name, a name-and-date pattern, or your own safe filename. Choose a name that identifies the set after it leaves your downloads folder, particularly when you produce several versions with different paper sizes or quality levels. File naming and the content shown on a cover are independent choices.
Prepare a batch for print, archive, or email
For printing, match the requested page size, leave practical margins, and prefer quality that keeps fine details legible. For a personal archive, prioritize a stable page order and a descriptive filename; an optional dated cover can help distinguish a packet from other files. For email, review the estimated output size and consider Compact or Balanced when the attachment limit matters.
The workbench accepts up to 25 images in one queue. Arrange them before creation, check that every intended thumbnail is present, and split larger groups into separate PDFs. After the progress indicator finishes, the file downloads automatically; a second download link remains available if your browser blocked the first attempt.
FAQ
Is cropping the same as changing page margins?
No. Cropping chooses which part of the image is kept; margins control the white space around that image on the PDF page.
How do I make a smaller PDF for email?
Choose Compact or Balanced JPEG quality, review the estimated size, and inspect the result. A smaller file can lose some fine image detail.
Can I use a cover title without uploading a cover picture?
Yes. An optional text cover can use a title, subtitle, or date without a separate cover image.
Can the file name include the date automatically?
Yes. Select the name-and-date template, or enter your own filename pattern in the file settings before creating the PDF.
