About this PNG to PDF converter
Turn PNG images into PDF files. PNG to PDF supports transparency and high resolution. Merge several PNGs into one document or create a single-image PDF.
What is a PNG file?
PNG (1996) is a lossless raster image format created as a patent-free replacement for GIF. It reproduces every pixel exactly, supports an alpha channel for transparency and up to 16 bits per channel, and compresses flat-colour areas very efficiently.
Strengths
- Lossless, so text and line art stay perfectly sharp
- Transparency (alpha channel)
- Ideal for screenshots, logos, charts and UI graphics
Limitations
- Photographs become 3 to 10 times larger than as JPG
- No animation in common use (APNG is rare)
- No native colour-management metadata in older files
Typical uses: Screenshots and diagrams; Logos and icons with transparent backgrounds; Images that will be edited again.
What is a PDF file?
PDF was created by Adobe in 1993 and has been an open ISO standard (ISO 32000) since 2008. A PDF page stores the exact position of every piece of text, image and line, together with the fonts it needs, so the page looks the same in every viewer and on every printer.
Strengths
- Looks identical everywhere, on screen and in print
- Fonts are embedded, so no substitution surprises
- Supports encryption, digital signatures, forms and bookmarks
- Opens in every browser and operating system without extra software
Limitations
- Hard to edit: the structure describes positions, not paragraphs
- Scanned PDFs contain pictures of text, not text, until OCR is run
- File size can balloon when images are embedded at full resolution
Typical uses: Contracts, invoices and official forms; Final versions of reports, theses and CVs; Scanned documents and archives; Print-ready brochures and books.
What changes when you convert PNG to PDF
Each image becomes a PDF page sized to the image, with no re-encoding of the picture data. The PDF has no text layer; run OCR afterwards if the images are of documents.
