How to turn PNG images into a PDF
- Choose the PNG images, one or many. Each one becomes a page.
- Drag the pictures into the order you want, or move them with the arrows. Turn one with Rotate left 90° or Rotate right 90° if it needs it.
- Choose the page: the picture’s own shape, or A4 or US Letter with a margin, fitted inside the page or filling it.
- Select Create PDF, then Download to save it.
Your pictures go in without loss
PDFCheetah keeps every pixel of each 8-bit PNG, stored without loss, and every transparent one with it; a 16-bit picture is written at 8 bits per channel, and the result says so. A see-through area stays see-through inside the file, so a logo or a cut-out sits on the page rather than in a white box, and nothing is ever re-saved as a JPG. A turn you choose is written as an instruction on the page rather than by redrawing the picture. Before the download appears, PDFCheetah opens the finished file again on this device, checks its page count and draws a sample of its pages.
Paper size, margins and fit
By default every page is the same shape as its picture, with no border, so a tall phone screenshot and a wide diagram each get a page that suits them. Choose A4 or US Letter to put every picture on the same paper: Fit the whole picture keeps everything visible with a border where the shapes differ, and Fill the page covers the paper edge to edge and trims what does not fit. A margin adds white space around the picture on either kind of page. The page you see in the preview is the page in the file.
Current limitations
This tool takes PNG files; a JPG photo has a tool of its own, and a HEIC or WebP picture needs converting first. No text is read out of the pictures, so a screenshot of a page is not searchable. Larger batches than this device can place safely are refused when you choose them, before anything runs.
Common questions
- Are my images uploaded?
- No. The PDF is put together in your browser, and your pictures are never sent anywhere. Download it, or use Share on a phone.
- Is transparency kept?
- Yes. A PNG goes into the PDF exactly as it was saved, and its transparent areas stay transparent inside the file, so a logo or a cut-out sits on the page rather than in a white box. Nothing is turned into a JPEG.
- Does converting reduce the quality of my images?
- No. A PNG is stored without loss: nothing is resized, nothing is turned into a JPEG, and an 8-bit picture keeps every pixel as it was. A 16-bit picture is written at 8 bits per channel, and the result says so.
- Can I put the images in a different order?
- Yes. Every picture appears in one preview, in the order it will be written, and any picture can be moved: drag it by its grip, use the arrows on it, or move it from the keyboard. Pictures can be turned or removed, and anything you change can be undone.
- Which page size will my images be on?
- Your choice. By default every page is the same shape as its picture, with no borders. Choose A4 or US Letter to put every picture on the same paper, fitted inside the page or filling it, with or without a margin.
