Free PNG to PDF converter

PNG to PDF, screenshots and graphics included

Drop your PNG files and get a PDF in seconds. Transparent areas become white, quality stays at 92 out of 100, and nothing leaves your browser. Up to 60 images per document, each up to 50 MB.

Pages match the exact shape of each PNG by default — a 1920 × 1080 screenshot stays 1920 × 1080. Switch to A4 or US Letter when you need a printable page.

Have a mix of formats, not just PNG? The image to PDF converter handles them all. Working with camera photos? JPG to PDF copies each JPEG in untouched.

How to convert PNG to PDF

Four steps, no upload queue, and the same result whether you brought one PNG or sixty.

  1. Add your PNG files

    Drop them on the box above, click it to browse, or paste a screenshot straight from the clipboard with Ctrl+V (Cmd+V on a Mac). Up to 60 PNG images per run, 50 MB each. Other formats like JPG, WebP and HEIC work too if you have a mixed batch.

  2. Arrange the page order

    Thumbnails read left to right, and that is the page order in the finished PDF. Arrows move one image at a time, Sort A→Z reads numbered filenames the way you count (Screenshot 2 before Screenshot 10), and Reverse flips the whole batch.

  3. Choose the page layout

    This page starts on Fit to image with no margin, so every page matches the exact shape of the PNG — ideal for screenshots and design exports. Switch to A4 or US Letter with a margin when the PDF is going to a printer.

  4. Convert and download

    Press Convert to PDF. The progress bar names each file as it is processed, then the download button shows the page count and finished size. Untick “All photos in one PDF” beforehand to get one PDF per PNG, zipped together.

How PNG transparency is handled

A PDF page carries photographic images as JPEG data via the /DCTDecode filter, and JPEG has no alpha channel. So when a PNG with transparency is converted, the alpha channel is composited onto a white background before encoding.

For screenshots with rounded corners, logos on a clear background, or design mockups with drop shadows, the white fill is usually exactly what you want on a printed or shared page. If preserving transparency is critical, a vector PDF editor that embeds PNGs natively is the right tool instead.

Frequently asked questions

How do I convert a PNG to PDF?
Drop the PNG on the box at the top of this page and press Convert to PDF — the download link appears seconds later. No account, no email, no software to install. Add more PNGs before converting and each one becomes a page of the same document.
What happens to PNG transparency?
Transparent areas are filled with white. A PDF page stores photographic images as JPEG data, and JPEG has no alpha channel, so transparency cannot survive the conversion. For most screenshots, logos and design exports, white is exactly the background you want on a printed page.
Does converting PNG to PDF lose quality?
PNG images are re-encoded as JPEG at quality 92, which is visually indistinguishable from the original for photographs and most graphics. The re-encode is capped at 16 megapixels per page by the browser's canvas. If your PNG is a simple diagram with sharp edges, you may notice very slight softening at extreme zoom — for anything else the difference is invisible.
Can I combine multiple PNGs into one PDF?
Yes — that is the default. Add up to 60 PNGs, leave “All photos in one PDF” ticked, and each image becomes one page in the order the thumbnails show. Untick it instead and you get a separate PDF for every PNG, delivered together as a single .zip download.
How do I convert a screenshot to PDF?
Copy the screenshot and press Ctrl+V (Cmd+V) anywhere on this page — it lands in the batch without being saved to disk first. The page is set to Fit to image by default, so the PDF comes out the exact shape of the screen capture with no white borders.
Is there a file size or page limit?
60 images per run and 50 MB per image. There is no daily quota, no paid tier and no waiting in a queue — the conversion runs on your own processor, not on a remote server, so the only real ceiling is your machine's memory.
Can I mix PNG with other image formats?
Yes. JPG, WebP, GIF, BMP, AVIF and HEIC (Safari only) can all go into the same batch alongside your PNGs. Each image becomes one page regardless of its format.
Are my PNG files uploaded anywhere?
No. Every step — reading the pixels, laying out pages and writing the PDF — happens inside this browser tab. No file, filename or metadata leaves your device. You can verify by watching the network panel in developer tools, or by disconnecting from the internet after the page loads and converting anyway.

Why Fit to image is the default for PNG

PNG is the format of screenshots, UI exports and graphic design output. Those images have a specific aspect ratio that means something — a 1440 × 900 screenshot is a laptop screen, not an A4 sheet. Dropping it on a standard page leaves white bars on two sides and shrinks the content.

That is why this converter opens with Fit to image and zero margin: the PDF page is built from the image's own pixel dimensions at 96 DPI, so a screenshot stays a screenshot. Switch to A4 or US Letter when the document has to be printed or submitted to a form that requires a standard page size.

Everything happens in this tab. The PNGs are never uploaded, and the only limits are your machine's memory and the 16-megapixel canvas ceiling that browsers impose when re-encoding.
