Why Use Our Images to PDF Converter?
A PDF page is a canvas with things placed on it, and an image is one of the things it can hold. That is the whole operation: make a page, embed the image, place it. No rendering, no re-encoding, no quality decision to make.
Which is why this conversion is lossless in a way most are not. The JPEG bytes that went in are the JPEG bytes that come out, wrapped in a PDF container. A tool that re-encoded them would be making the file worse for no reason.
The only real choice is the page. Fit gives each page the exact pixel dimensions of its image, treating a pixel as a point — the right answer when the images are already the shape you want and you never intend to print. A4 or Letter puts every image on the same sheet, scaled to fit inside the margins and centred, which is what you want when the file is going to a printer or into a document set.
Scaling always contains and never crops. An image wider than the sheet is made smaller until it fits; it is never cut off to fill the page. Losing the edge of a receipt to make it fill an A4 page is not a trade anybody wants.
How it compares
Most image-to-PDF sites upload your files. Photographed documents are usually the ones you would least like sitting on a stranger's disk — receipts carry card details, scanned letters carry addresses. This page never sends them anywhere.
Desktop apps do the job well and cost an install for something you may need twice a year. Going the other way, PDF to Image turns PDF pages back into JPG or PNG, and PDF Merger joins the result to other PDFs.
Images to PDF Tips
- Fit gives a page exactly the size of each image, which is right when the images already have the shape you want.
- A4 and Letter centre each image on a fixed sheet and never crop it — the image is scaled to fit inside the margins.
- Images are embedded as they are and never re-encoded, so nothing is lost and the PDF is about as large as the images were.
- JPG and PNG only. The format is read from the file's own bytes, so a mislabelled extension still works.
- An image the tool cannot read is named under the result rather than dropped silently.
