How to Convert JPG and PNG Images to PDF
Putting images into a PDF is useful for scanned paperwork, receipts, illustrated notes, and photo-based instructions. A single PDF gives the recipient one document to open and print instead of a folder of separate pictures. PDFSwan Images to PDF accepts JPG and PNG files and places each image on its own PDF page.
Open Images to PDF ↗When to use Images to PDF
Use Images to PDF when your starting files are JPEG or PNG images. You can combine those two formats in the same task, arrange their sequence, and choose page size and margins. The tool embeds images; it does not recognize printed words with OCR, turn a photograph into editable text, or accept Word documents and HEIC files.
Step-by-step instructions
Prepare JPG or PNG files
Open your pictures first and check that they are upright, readable, and cropped as you want them. This workspace does not offer image cropping or rotation controls. If your phone produced HEIC files, export copies as JPG or PNG before adding them.
Add and arrange the images
Open Images to PDF. Choose images from your device or drag them into the drop area. Use the up and down arrows beside each filename to set the sequence. Every file becomes one page, so the first image in the list becomes the first PDF page.
Choose the page size
Under Page size, select A4 portrait, US Letter, or Fit to image. A4 and Letter use fixed portrait pages and scale each picture proportionally to fit. Fit to image bases each page on that picture’s dimensions plus the selected margin, so pages can vary in shape and size.
Set margins
Choose Small, None, or Generous. Small uses a 24-point inset and Generous uses 48 points around the available image area. None removes that inset. With fixed page sizes, an image can still leave empty space because its proportions differ from the page; removing margins does not crop it to fill the page.
Create and download the PDF
Set File name, select Create PDF, then Download PDF. Open the result and check that each picture is clear, in sequence, and fully visible. If you intend to print it, review the print preview and paper size before printing the whole document.
A practical example
To turn four receipt photos into a single expense document, export the images as JPG, add all four, and move them into date order. Choose A4 portrait with Small margins for a consistent page size. Create the PDF and confirm that it has four pages. A very wide receipt may look small on a portrait page; crop or rotate the source image beforehand if necessary.
Tips for a better result
Choose print-friendly or image-sized pages
A4 and US Letter are useful when a recipient expects standard paper sizes. Fit to image is useful when preserving different image proportions matters more than consistent paper. An image’s pixel dimensions do not by themselves guarantee a particular physical print size; inspect the resulting page setup.
Protect readability
A low-resolution or blurry source cannot become sharper simply by converting it to PDF. Start with a readable image and avoid unnecessary resizing before conversion. The tool fits the entire picture, so unwanted borders and background areas in the source remain visible.
Stay within the limits
Use at most 60 files, 50 MB in total, and 300 output pages per task. Each image must be below the 40-megapixel limit. Since there is one page per image, the 60-file cap is the practical page cap for this tool. Resize oversized pictures before trying again.
Troubleshooting
Why is my image rejected?
The supported formats are JPG and PNG. Renaming a HEIC or WebP extension to .jpg does not convert its contents. Export a genuine JPG or PNG copy and add that copy.
Why is there white space with no margins?
The picture keeps its proportions. On an A4 or Letter page, a different aspect ratio leaves spare space. Choose Fit to image with None, or crop the source image to match your intended page shape.
Why can I not select text in the result?
The PDF contains embedded pictures. There is no OCR step, so photographed words do not automatically become selectable or searchable text.
File limits, privacy and keeping your originals
PDFSwan processes document bytes locally in your browser without a document upload. The task limits are 50 MB total input, 60 files, and 300 PDF pages. Actual performance depends on your device and browser memory. Encrypted PDFs are rejected; choose an unlocked copy you are authorized to edit. Keep your originals, because page operations and edits may change bookmarks, forms, links, annotations, and existing digital signatures.
The home page includes Google Analytics and DeanonX site-tracking scripts. Local document processing does not mean the website has no third-party tracking. Download the result before closing the tab, and use Clear workspace to remove files from the active workspace when finished.
Frequently asked questions
Can I combine JPG and PNG files into one PDF?
Yes. Add both supported formats and arrange them with the file arrows before creating the PDF.
Can I put several images on a single page?
The current tool creates one page per image. It does not provide a collage or contact-sheet layout.
Can I convert a PDF back to images?
Yes. Use PDF to JPG or PDF to PNG to export one image per page in a ZIP archive.
Will conversion compress my photos?
This is a conversion tool, not a compression workflow. Output size depends on the source images, and a smaller file is not guaranteed.
