You have a stack of screenshots, scanned pages, or photos as PNGs and you need them in a single PDF. Maybe it's for a client deliverable, a portfolio, or an insurance claim that wants one document. Here is the workflow.
How to convert PNG to PDF
- Open the PNG to PDF converter
- Drop your PNG files into the upload area (or click to browse)
- Choose your page size — A4, Letter, or Fit Image
- Pick orientation (portrait or landscape)
- Toggle margins on or off
- Hit Download PDF
That's it. The entire conversion happens in your browser — your files never leave your device.
Choosing the right settings
Page size matters more than people think.
- A4 (210 × 297 mm) — standard for most of the world. Use this for documents that might be printed.
- Letter (8.5 × 11") — standard in the US and Canada. Use this if your recipient is American.
- Fit Image — the PDF page matches the exact dimensions of your image. Use this for photos, graphics, or anything where you don't want white borders.
Margins add a small border around the image on each page. Turn them on for documents that will be printed (so content isn't cut off at the edges). Turn them off for photos or graphics where you want full-bleed.
Orientation should match your images. Landscape screenshots look wrong on a portrait page with huge white bars above and below.
Multiple images in one PDF
You can upload several PNGs at once. Each image becomes its own page in the PDF. Before downloading, you can drag to reorder the pages — useful when you're assembling a multi-page document from individual screenshots.
If your PNGs are larger than the destination allows, consider testing copies with the Image Compressor first. Compare the visual result and final PDF size before discarding the originals.
Why PDF instead of just sending the PNGs?
Three reasons:
- One file instead of many. A PDF with 12 pages is easier to share than 12 separate PNGs.
- Consistent formatting. The recipient sees exactly what you see — same layout, same page order, same sizing. PNGs in a folder can be viewed in any order.
- Broad compatibility. PDFs are widely supported and preserve page order more clearly than a folder of separate images.
For formal documents — contracts, portfolios, reports, insurance claims — PDF is the expected format. Sending raw image files looks unprofessional in contexts where a polished document is expected.
If part of the document is already a PDF, create the image-based PDF first and then use Merge PDF to combine the two files. If the finished document is still larger than its destination accepts, try the PDF Compressor and compare the before and after sizes.
Common problems and how to avoid them
Pages come out in the wrong order. Pages follow the order of your images, so check the thumbnails before you download. If you named files scan1.png, scan2.png … scan10.png, many file pickers sort scan10 right after scan1. Rename with leading zeros (scan01, scan02) or reorder by dragging in the converter.
Screenshots look tiny on a page. A 1,000-pixel-wide screenshot on an A4 page at the default margins is surrounded by white space. If the PDF is for screen reading, "Fit Image" avoids the borders; if it will be printed, keep a standard page size and accept the margins.
The PDF is much bigger than you expected. A PNG is lossless, so photographs and full-screen screenshots are large, and the PDF carries every one of them. Twelve 3 MB screenshots make a PDF of roughly 36 MB, which many email systems reject. Compress the PNGs first, or compress the finished PDF, and compare the result at the zoom level people will actually view it.
Text in the image can't be searched. A PDF made from PNGs is a set of pictures. You can't select or search the words in a screenshot unless the document goes through OCR (optical character recognition), which this converter doesn't do. If searchable text matters, export the original document to PDF instead of screenshotting it.
A quick checklist before you send it
- Open the PDF and scroll through every page, not just the first.
- Zoom to 100% on a page with small text and confirm it is still readable.
- Check the file size against the limit of wherever it is going (email attachment, upload form, claims portal).
- Keep the original PNGs until the recipient confirms they received a usable file.
PNG, JPG or PDF: which should you send?
Send a PDF when the recipient needs a document: several pages in a set order, something to print, or something to sign or file. Send the images themselves when they will be edited or reused, such as a logo or a photo for a layout. If you only have one picture and the destination accepts images, a PDF adds nothing. For photos specifically, the PNG vs JPG vs WebP guide explains which image format is the right starting point before you convert.
Can I combine multiple PNGs into one PDF?
Yes. Upload multiple PNGs and each one becomes a separate page in the PDF. You can drag to reorder pages before downloading. The practical batch size depends on image dimensions and available memory in your browser and device.
Will converting PNG to PDF reduce the image quality?
The converter preserves the source image for the page workflow, but page sizing or later compression can affect the final result. Inspect the downloaded PDF at the intended zoom and keep the source PNGs.
What page size should I use?
Use Letter (8.5 × 11") for US documents, A4 for international. Use "Fit Image" if you want the PDF page to match the exact dimensions of your image — this avoids any white borders or scaling.
