how to convert png to pdf
Drop your PNG file
Drag your PNG file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs jsPDF on your device to decode the Portable Network Graphics and encode it as Portable Document Format. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the PDF file
When the conversion finishes, the PDF file is ready to download. Save it anywhere on your device.
FAQ
common questions
Can I combine multiple PNGs into one PDF?
Yes — drop several PNG files in and the converter packages them as a multi-page PDF, one image per page, in the order you provided. Each page sizes to its image's dimensions, keeping the source aspect ratios intact.
Does transparency in my PNG survive in the PDF?
Yes. PDF supports transparency natively (it's been part of the spec since PDF 1.4 in 2001), and the converter passes your PNG's alpha channel through cleanly. The PDF page background is white by default, so transparent PNG regions will composite against white — but the transparency information itself is preserved, which matters if the PDF will be used in design workflows that layer pages over backgrounds.
Why use PNG → PDF instead of PNG → ZIP?
PDF guarantees identical rendering on every device — every reader opens it the same way, page-by-page navigation is built in, and printing works predictably. ZIP is a delivery mechanism; PDF is a presentation format. For documents (contracts, design hand-offs, image portfolios) PDF wins. For raw asset bundles (image sets that designers will re-open and edit), ZIP makes more sense.
Will the PDF be searchable?
No — the PDF embeds PNGs as page images. The text rendered inside those images isn't selectable or searchable text in the PDF. If you need searchable content from screenshot PNGs or document scans, run OCR on the PDF output afterward (Acrobat, ABBYY FineReader, or Tesseract).
How does the file size compare to the source PNGs?
Roughly the sum of the input PNGs plus minimal PDF wrapper overhead. PNG data is stored compressed inside the PDF (no re-encoding), so three 1 MB PNGs typically become a 3.0–3.1 MB PDF. The PDF is no smaller than the sum of inputs — for transparency-heavy assets where PNG is already the right format, that's expected.
