How to convert PNG to PDF
To convert PNG to PDF with ZeroUploads, tap Choose photos and pick your PNG files, or drag and drop them. Put them in order, tap Create PDF if you're on a phone, select Printing to keep full resolution and transparency, then tap Download PDF. The PDF is made on your device, and no file is uploaded.
Tap Choose photos and pick one or more PNG files. You can also drag and drop them, or paste a copied image or screenshot.
Drag the images into the order you want. Use the ⋯ button on an image to rotate, duplicate or delete it.
On a phone, tap Create PDF first. Choose what the PDF is for: Printing keeps full quality and transparency; Upload forms (pick the form's limit) and Email & chat make it smaller.
Tap Download PDF. Your browser saves one PDF with every image on its own page. On an iPhone or iPad, tap Share, then Save to Files.
Convert PNG to PDF without losing quality
With Printing selected, each PNG goes into the PDF at full resolution. The converter stores it with lossless compression, the kind PNG files use themselves, instead of turning it into a JPG, so the text in a screenshot and the edges of a logo stay sharp.
In our test, a desktop screenshot, a phone screenshot and a photo saved as PNG came out with 0 pixels changed. Each PDF was about the size of its PNG: a 4.2 MB PNG made a 4.2 MB PDF, and a 92 KB screenshot a 106 KB PDF.
With Upload forms or Email & chat, the images are compressed as JPG so the PDF fits the size limit, and quality drops.
PNG to PDF with a transparent background
Transparent areas of a PNG stay transparent in the PDF. With Printing, the converter keeps the PNG's transparency (its alpha channel) as a mask instead of filling it in, so on the page you see the white paper behind the image.
In our test with a logo on a transparent background, the transparency in the PDF matched the PNG exactly. With a size limit, the image is saved as a JPG, which can't be transparent, so transparent areas turn white.
Combine multiple PNG files into one PDF
Add your images in one go, or a few at a time with the Add button. Each PNG becomes one page, in the order you see on screen. Drag an image to move it, or sort them by name or by date. Switch to the list view to see file names and sizes.
You can mix PNG, JPG and other images in the same PDF. Use the ⋯ button on an image to rotate it, duplicate it or delete it.
PNG to PDF under 100 KB, 200 KB or 300 KB
Many upload forms accept only small files. Choose Upload forms and pick the form's limit (100, 200, 300 or 500 KB): the converter compresses and resizes the images, step by step, until the whole PDF fits. If it can't get under the limit, it tells you and shows the size it reached.
To fit, the images are saved as JPG, so a transparent background turns white. Email & chat keeps the PDF under 1 MB the same way.
Page size, orientation and margins
A4 is the default; choose Letter for the US and Canada. Fit makes each page the size of its image; with Margin set to None, there's no white border.
Orientation is set to Auto, so a landscape image gets a landscape page and a portrait image a portrait page. Choose Portrait or Landscape to use one orientation for every page; with Fit, the page always follows the image's shape. Images are never cropped or stretched: they are scaled to fit the page and centered, so A4 or Letter can leave white space when the image has another shape. Margin adds a small or big white border around each image.
Your PNG files never leave your device
The PDF is built by code running in your browser, on your phone or computer. There's nothing to install, and your images are never sent anywhere.
In our test, converting a PNG sent no request carrying any file data.
