PNG to PDF without touching a pixel
PNG is the format of screenshots, diagrams, scanned line art and UI captures — anything where hard edges matter. This converter embeds your PNGs into the PDF exactly as they are: no re-encoding, no resampling, no quality loss. A PDF built from PNGs is pixel-identical to the source images.
Why bundle PNGs into a PDF at all
- One file instead of twenty. A bug report with fifteen screenshots, a scanned sketchbook, a set of design comps — as a single PDF it emails cleanly, previews everywhere, and prints in order.
- Fixed order and page size. Image attachments arrive in whatever order a mail client feels like; PDF pages don't. Auto page size gives each page its image's exact dimensions; A4/Letter puts every image on a standard sheet with your margin.
- Screenshots stay legible. JPG smears sharp text edges; PNG doesn't, and neither does this conversion. For photo batches where file size matters more than edges, [Images to PDF](/images-to-pdf) takes JPGs and mixed formats.
Things worth knowing
- Transparency flattens to white. PDF pages have a background, so transparent PNG regions render over the page. Flatten onto a chosen color first if it matters.
- Lossless in, large out. Big PNGs make big PDFs since nothing is recompressed. If the result is heavy, [Compress PDF](/compress-pdf) in smart mode will downsample the embedded images on your terms.
- Text in the images isn't searchable. Each PNG becomes a picture on a page. Run the result through [OCR PDF](/ocr-pdf) to add a selectable text layer over screenshots of text.
Related workflows
Interleaving PNGs between pages of an existing PDF is [Merge PDF & Images](/merge-pdf-images). Going the other direction — pulling pages out of a PDF as images — is [PDF to Images](/pdf-to-images) (PNG) or [PDF to JPG](/pdf-to-jpg). Files up to 100 MB each, processed over HTTPS and deleted afterward.

Frequently Asked Questions
Does converting PNG to PDF lose quality?
No. PNGs are embedded in the PDF as-is, not re-encoded — PNG is lossless and stays lossless, so screenshots, line art and text captures keep their exact pixels. That also means a large batch of big PNGs produces a large PDF; run it through Compress PDF afterward if size matters.
What happens to transparency in my PNG?
A PDF page has a background, so fully transparent regions render over the page's white. If your PNG relies on transparency for effect, flatten it onto the background color you want in an image editor before converting.
Can I combine several PNGs into one PDF?
Yes — that's the main use. Add as many PNGs as you like, drag nothing: the numbered badges show the page order, and each image becomes one page. Auto page size gives every page its image's exact dimensions; A4 or Letter puts each image on a standard sheet.
Why PNG for screenshots instead of JPG?
Screenshots are sharp-edged text and UI, which JPG compression visibly smears. PNG keeps those edges perfect, and this converter keeps the PNG data untouched inside the PDF — so a PDF of screenshots stays as crisp as the originals.
Can I mix PNGs with JPGs or existing PDF pages?
For mixed image formats use the general Images to PDF tool (JPG, PNG, WebP, GIF, BMP, TIFF). To interleave images with pages from existing PDFs, use Merge PDF & Images.
