Turn PNG images into a PDF

or drop them here
Choose at least one JPG or PNG image first.

Choose PNG images, put them in order, and build one checked PDF without an upload and without resampling a single image. Lossless pixels and transparency stay intact. Match each page to its image or use A4 or US Letter with no margin, a narrow margin or a standard margin. Page geometry and embedded pixel dimensions are verified before download.

How to turn PNG images into a PDF

  1. Choose PNG images

    Choose one or more .png files, or drop them on the page. Lossless pixels and transparency stay in this tab.

  2. Put them in order

    Use the arrow buttons to set the page order. Each PNG image becomes one PDF page.

  3. Choose the page fit

    Match each page to its image, or use A4 or US Letter. Add no margin, a narrow margin, or a standard margin.

  4. Read the receipt, then download

    The completed PDF is opened again. Its page count, page sizes and embedded image dimensions must match before the download appears.

What goes into the PDF

Each PNG is embedded through the PDF writer's native PNG path. The image keeps its lossless source pixels, pixel dimensions and alpha channel. The verifier then checks every page size and the raw pixel width and height of every embedded PNG.

Where PNG to PDF fits

pdfpix is a free online PNG to PDF converter with no account needed and no daily cap. The page arrives over the network, but the convert step does not use it: each PNG is read and written into the PDF inside this browser tab, so the images never reach a server and nothing waits in a queue.

PNG is a lossless format, and it stays lossless here. The image goes into the PDF through the writer's native PNG path, which keeps the exact source pixels, the pixel dimensions and the alpha channel. Nothing is resampled, re-encoded or downscaled, so a screenshot of small type stays as readable in the PDF as it was on screen. Transparency is preserved rather than flattened onto white, which matters for a logo or an interface capture with rounded corners.

Lossless also means large. A set of PNG screenshots can weigh more than the application that produced them, because no lossy compression exists anywhere in the chain. If the finished file is too big to email, run it through Compress PDF, which reduces image data without turning selectable pages into pictures, or open Size breakdown first to see which pages carry the weight.

To merge these pages into a report you already have, use Merge PDF. To reorder or delete pages after the fact, use Organize pages. For a mixed folder of PNG, JPG and HEIC files in one pass, use Images to PDF, and Combine screenshots into a PDF covers ordering a long capture set.

Questions

Are my PNG files uploaded?
No. The PDF writer and output checks run in this browser tab.
Does PNG to PDF change image quality?
No. Each PNG is embedded without resampling. Its lossless source pixels and pixel dimensions are kept.
What happens to transparent areas?
The PNG alpha channel is kept in the PDF. A PDF viewer normally shows the unpainted page beneath it as white.
Can I mix portrait and landscape PNGs?
Yes. Fixed paper sizes turn automatically for landscape images. Match image gives every page the shape of its source image.
Does it make screenshot text selectable?
No. Text inside a PNG is made of pixels. This conversion does not run OCR.
What does the PNG to PDF check cover?
It reopens the completed PDF and checks the page count, every page size, and the pixel width and height of each embedded image. A failed result is not offered for download.

The other pdfpix tools

All 30 of them run in a browser tab like this one. Each reads its own output back and checks it before offering the download, and none of them needs an account.
