How to Combine JPG and PNG Images into One PDF

Prepare the source images first

Collect only the images that belong in the final PDF. JPG is common for photographs; PNG is useful for screenshots, line art, and images that need transparency before they enter the PDF. The current Images to PDF interface accepts JPG/JPEG and PNG, so convert HEIC, SVG, TIFF, or WebP files in a separate step before starting.

Check rotation and crop before assembly. The tool places each image on its own page but does not rotate, crop, add captions, or normalize every page to Letter or A4. If one image is sideways or has a different aspect ratio, that difference will remain visible in the result.

1. Remove accidental duplicates and unwanted files.
2. Rotate or crop each source image as needed.
3. Use simple filenames such as 01-cover.jpg, 02-introduction.png, and 03-page.jpg to make the intended sequence easy to inspect.

Select files in the final reading order

Open Images to PDF and choose the files in the order in which readers should see them. The current version preserves the order supplied by the file picker or drop action. It does not provide a separate drag-and-drop reorder screen after selection, so ordering is a preparation step rather than a later editing step.

Operating systems can present selected files differently, especially when names contain unpadded numbers such as page-1, page-2, and page-10. Numbering with leading zeros gives you a simple visual check. If the file picker does not return the intended sequence, cancel, rename the sources, and select again.

1. Open the Images to PDF tool.
2. Select every required JPG and PNG in final order.
3. Review the selected-file count before processing.

Create one PDF and verify the output

Start the local process and wait for the PDF download to become available. Each image becomes one PDF page. The output is a new file, so the original images stay unchanged. The PDF page dimensions follow the embedded image dimensions used by the current assembly engine rather than a paper-size layout chosen by the user.

Open the download in a PDF viewer. Check the first and last pages, then move through every transition where the source file changes. Confirm page count, sequence, orientation, cropping, and whether any source looked unexpectedly soft. A successful download proves that a file was created; it does not prove the document is ready for a printer or publisher.

1. Create and download the PDF.
2. Confirm that the PDF page count equals the number of selected images.
3. Inspect every page at normal view and any text-heavy pages at 100% zoom.

Plan for printable and shareable results

For a screen-only review copy, consistent order and readable images may be enough. For printing, start with the required physical page size and pixel dimensions. An image can look large on screen yet be insufficient for a chosen print size. Use the DPI / Print Checker on representative sources when sharpness matters.

Images to PDF does not add bleed, safety margins, color profiles, searchable text, bookmarks, encryption, or printer marks. If a print provider requires those features, build the final layout in software designed for print production and treat this tool as a quick assembly step or proofing workflow.
