How do I convert PNG to PDF?

Drop your PNG files onto the dropzone, decide whether to combine them into one PDF or make one per image, set the page size and background, then click convert. The PDF is assembled on your device and downloads directly to you, with no upload step.

What happens to the transparent parts of my PNG?

They are flattened onto a solid background before the image is placed, because a PDF page cannot be transparent. The default fill is white, but you can pick another color. Anything that was see-through in the PNG shows that background color in the finished PDF.

Can I change the background color behind transparent areas?

Yes. The background color setting fills every transparent pixel when the image is flattened onto the page. White works for most documents, but you can set any color you like so the result matches your design or brand.

Can I merge several PNG files into one PDF?

Yes, and it is the default with more than one file. Each PNG becomes a page in the order you dropped the files, and the set saves as one combined PDF. Prefer them apart? Choose one PDF per image and each is exported on its own instead.

What page size does the PDF use?

Your choice. Pick Image so each page matches its PNG exactly, or A4 or Letter for standard pages. For A4 and Letter you also set orientation, a margin, and whether the image is contained within the page or fills it edge to edge.

Does converting to PDF improve my PNG's quality?

No. The page shows the same graphic your PNG already held; wrapping it in a PDF adds no sharpness or detail. The only thing that grows is file size, since large PNG exports carry their full resolution into the document.

Will text inside my PNG screenshots be searchable?

No. This tool places each PNG onto a page as an image and does not run OCR. Any words in a screenshot stay part of the picture, so they cannot be selected or searched in the PDF. Use a dedicated OCR tool if you need searchable text.

Are my PNG files uploaded anywhere?

No. Each file is decoded, flattened, and built into the PDF inside your browser with WebAssembly. Nothing is sent to a server, copied, or stored. Watch the Network tab in your browser's developer tools while it runs and you will see no upload.

What happens to PNG transparency in a PDF

Start with the thing that trips people up: a PDF page is opaque, so the transparent parts of your PNG cannot stay see-through. Before each image is placed on a page it is flattened onto a solid background — white by default. A logo with a clear surround will land on a white rectangle, and a screenshot with rounded, transparent corners will show those corners filled in. This is expected, not a bug. If transparency matters to your design, a PDF is simply the wrong container for it.

With that understood, PNG to PDF is a great fit for the flat, crisp graphics PNG is known for. Diagrams, wireframes, UI screenshots, charts, and exported slides all keep their sharp edges as pages of a document that opens identically everywhere. Each PNG becomes one page in the order you drop the files. Add several and the default is to combine them into one PDF; prefer separate files and you can output one PDF per image instead. A single PNG makes a clean one-page document.

You control the page too — match each image's own dimensions, or standardise to A4 or Letter with an orientation, margin, and fit that suits printing. A few honest limits: wrapping a PNG in a PDF never improves its quality, large screenshots produce a heavier file, and EXIF metadata is stripped by default. This tool lays images onto pages only — it does not run OCR, so text inside a screenshot stays part of the picture and will not be selectable or searchable.

Transparency handled predictably

Clear areas are flattened onto a solid background before they hit the page, so you always know exactly how the PDF will look — no surprise checkerboard, no half-transparent edges.

Combine or keep separate

Merge every PNG into one document, or produce a PDF per image. The combined file saves as a single download; separate files return together as a ZIP.

Processed on your device

The whole thing runs locally with WebAssembly — your PNG files never travel to a server. Check the Network tab as it converts and nothing uploads.

When converting PNG to PDF helps

Sharing UI screenshots

App and website screenshots exported as PNG bundle neatly into one PDF for a review, a spec, or a bug report the whole team can page through in order.

Delivering diagrams and charts

Flowcharts, wireframes, and exported charts keep their crisp lines as document pages, so a client or colleague opens one file instead of a scatter of images.

Turning slides into a handout

Slides or design boards exported as PNG become a paged PDF that reads like a leave-behind — easy to print or attach to an email.

Packaging a logo pack

Send brand marks as a PDF proof sheet. Set the background to match your guidelines so the flattened transparency lands on the color you intend.

Archiving design exports

Combine a project's PNG exports into a single dated PDF for your records, far tidier to store and reopen than dozens of separate files.

Submitting to a PDF-only form

Applications and portals that accept PDF only will take your PNG artwork once it is wrapped into a document with this tool.

How to convert PNG to PDF in three steps

Drop your PNG files
Add a single graphic or up to fifty. Each PNG joins the queue in the order you drop it, and that order becomes the page order in your PDF.
Choose page and background
Pick combine into one PDF or one PDF per image, then set page size (Image, A4, or Letter) with orientation, margin, fit, and DPI. The background color fills any transparent areas — white unless you change it.
Download your PDF
A combined document downloads as one PDF. Choosing one per image gives you each file separately, or the full set bundled into a single ZIP.

Tips for clean PNG-to-PDF results

Tip 1:
Set the background color before converting. It fills every transparent area, so choose white for documents or a brand color when the surround should match your design.
Tip 2:
If a transparent background actually matters, keep the PNG — a PDF page can't stay see-through, so flattening is unavoidable here.
Tip 3:
Large screenshots make large PDFs. Compress or resize wide, high-resolution PNGs first if you need a document light enough to email.
Tip 4:
Want the text in a screenshot to be selectable? This tool places the image as a picture; reach for a dedicated OCR tool to get a searchable PDF.
