Why this works
Combine one or more PNG images into a single PDF \u2014 the right pick when your source images contain text, screenshots, line art, or anything with sharp edges that JPG compression would soften.
PNG and JPG are both raster image formats, but they serve different jobs. PNG uses lossless compression and preserves transparency \u2014 every pixel is exactly what you put in, and transparent regions stay transparent. JPG uses lossy compression and has no transparency \u2014 it\u2019s smaller, but every save degrades the image and any transparent areas turn into solid colour.
For PDF assembly: pick PNG to PDF when your source images are screenshots, web designs, line art, text-rendering, or anything with sharp high-contrast edges \u2014 JPG compression introduces visible artefacts on these images (fuzzy haloes around text, blocky distortion on line edges). Pick JPG to PDF when your sources are photographs \u2014 JPG\u2019s lossy compression is imperceptible on photographic content and produces much smaller files.
Drop multiple PNGs in any order; drag them into the order you want as PDF pages. Each PNG becomes its own page in the output PDF. Transparency in the source PNG is composited onto a white page background (PDF pages don\u2019t have inherent transparency the way PNG canvases do); if you need a coloured background, set it in the PNG before converting.
The original pixel data is embedded into the PDF without re-encoding \u2014 your output PDF page is bit-identical to the source PNG in image quality. File sizes can be large compared to JPG-based PDFs because PNG is uncompressed-ish; if the output is too big for your downstream use (email attachment, upload form), run it through Compress with the Recommended setting.
For multi-page documents photographed or screenshotted page by page, the workflow is: capture each page as a separate PNG (a phone screenshot, a screen-grab, an export from your design tool), drop them in upload order, convert. The combined PDF preserves the original screen-resolution sharpness across every page.

Real-world uses
Designers
Bundle a sequence of design mockups (each exported as PNG to preserve sharpness) into one client-facing PDF deliverable.
Developers
Combine application screenshots into a bug-report PDF where text remains crisp and readable.
Trainers
Slide-screenshot decks into a single PDF handout without the JPG fuzziness that would obscure code samples.
QA teams
Test-result screenshots packaged into one shareable PDF for sprint reviews.
Common questions
PNG to PDF or JPG to PDF \u2014 which should I pick?
Pick PNG to PDF for screenshots, line art, designs, anything with text or sharp edges. Pick JPG to PDF for photographs. PNG preserves every pixel losslessly; JPG compresses photographically but introduces visible artefacts on sharp edges.
Will transparent areas stay transparent?
No. PDF pages don\u2019t have inherent transparency \u2014 transparent regions in the source PNG composite onto a white page background. If you need a coloured background, set it in the PNG itself before converting.
Will the image quality drop?
No. PNG bytes are embedded directly without re-encoding. The image inside the PDF is bit-identical to the source PNG \u2014 same pixels, same colours.
Why is my PNG-based PDF so big?
PNG\u2019s lossless compression isn\u2019t as space-efficient as JPG\u2019s lossy compression \u2014 a 10-page PNG-to-PDF can be 30+ MB if the sources are high-resolution screenshots. Run the output through Compress to shrink it; the Recommended setting reduces size meaningfully without visible quality loss on screen.
How many PNGs can I combine?
No hard cap on count, only on combined size. Free accounts handle up to 25 MB of inputs; Pro lifts to 500 MB. Typical screenshots are 1\u20133 MB each.
Can the output be made searchable?
Yes \u2014 if the PNGs contain readable text (e.g. screenshots of documents). Run the converted PDF through OCR to add an invisible searchable text layer.
