PNG to PDF Converter

Convert a PNG file to PDF right here in your browser. Nothing is uploaded: the conversion runs on your own device, so it is private, has no file size limit set by a server and works offline once the page has loaded.

Add a file from a URL

The file is fetched by your browser straight from that website, not through our servers. It works when the site allows other websites to download its files.

    What happens when you convert PNG to PDF

    • The PNG is placed on a PDF page the same size as the image, stored losslessly.

    How to convert PNG to PDF online

    1. Press "Choose PNG files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
    2. Adjust the settings if you need to. The output is lossless, so there is no quality setting to worry about.
    3. Press "Convert to PDF". Images convert in a second or two each.
    4. Save each PDF with its download button. Close the tab and every trace of the files is gone from memory.

    Why convert PNG to PDF?

    PNG files usually come from screenshots, logos, diagrams and anything with transparency. People convert them to PDF because a PDF looks the same on every device and is what forms, portals and printers ask for.

    In short, PNG is good at what it was made for, and PDF is the more practical choice when the file has to open, upload or print somewhere else. PNG opens in every browser and image viewer, while PDF opens in every browser's built-in viewer.

    How to convert PNG to PDF on Windows, Mac, iPhone and Android

    Best settings for PNG to PDF

    Each image becomes one page sized to the image at 96 pixels per inch, so a 1200 pixel wide image makes a page 12.5 inches wide. PDF viewers and printers scale pages to fit, so the page size rarely matters on screen.

    The PNG is stored with lossless compression inside the PDF, so it is exactly as sharp as the original. Transparent areas are placed on a white page.

    About PNG and PDF files

    What is a PNG file?

    PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.

    What is a PDF file?

    A PDF fixes the layout of every page so it looks the same on any device. Converting a PDF to an image renders each page to pixels; converting an image to PDF wraps it as a page.

    PNG to PDF not working? Common problems

    • Colours look slightly different. Browsers convert images to the standard sRGB colour space when they decode them, so wide-gamut and CMYK images can shift a little.
    • A phone photo comes out upright even though it looked sideways elsewhere. That is correct: the rotation stored in the photo is applied during conversion, so the PDF is always the right way up.
    • Transparent areas turned white. PDF cannot store transparency; convert to PNG or WebP instead if you need it.

    Convert PNG to PDF from the command line

    If you work in a terminal, ImageMagick converts PNG to PDF in one line:

    magick input.png output.pdf

    To convert every PNG in a folder at once, use magick mogrify -format pdf *.png. The converter on this page does the same job without installing anything.

    PNG to PDF converter FAQ

    Will I lose quality converting PNG to PDF?

    No. PDF is written losslessly, so the result matches the PNG exactly.

    Why is the PDF a different size from the PNG?

    It depends on the settings. At the defaults, the PDF usually comes out close in size to the PNG; lower the quality for a smaller file.

    Are my PNG files uploaded anywhere?

    No. The conversion runs inside this browser tab using your browser's own image decoder, so your files stay on your device. You can disconnect from the internet after the page has loaded and it still works.

    Can I convert several PNG files to PDF at once?

    Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.

    How do I open a PDF file?

    PDF opens in every browser's built-in viewer. PDF is common for documents, forms, invoices and print-ready files.

    Is this PNG to PDF converter free?

    Yes. There is no sign-up, no watermark and no limit on how many files you convert. The site is paid for by advertising, and because conversions run on your device there is no server cost per file.

    Can I convert PNG to PDF on my phone?

    Yes. The converter works in Safari on iPhone and iPad and in Chrome on Android. Converted files are saved to the Downloads folder.
