Why convert PNG to PDF?

  • Share screenshots as a document — bug reports, tutorials and receipts in a single file.
  • Archive diagrams — PDF is a stable, widely supported format for long-term storage.
  • Print — fixed page sizes make printing simple.

How the conversion works

Each PNG becomes one page of the PDF, in the order you set. Images are embedded losslessly, and with a fixed page size they are scaled to fit within the margins and centred on the page.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless image format: every pixel is stored exactly, so text, lines and screenshots stay perfectly sharp. PNG also supports transparency, which makes it the usual choice for logos, diagrams and interface graphics.

Because nothing is discarded, PNG files of photos are larger than the same photo saved as JPG.

What is a PDF file?

PDF (Portable Document Format) was created by Adobe and is now an open ISO standard (ISO 32000). A PDF fixes the exact layout of every page — fonts, images and positions — so a document looks the same on every screen and printer. That makes it the standard for contracts, invoices, manuals, papers and forms.

Inside, a PDF stores each page as drawing instructions. Text written by a program is stored as real characters (a “text layer”) and can be selected and extracted. Scanned documents usually store only a picture of each page, so their text cannot be extracted without OCR.

Frequently asked questions

Is the image quality preserved?

Yes. PNG images are stored losslessly, so screenshots and text stay perfectly sharp in the PDF.

What happens to transparent areas?

Transparency is kept in the PDF. PDF viewers usually show transparent areas over a white page.

Can I combine screenshots of different sizes?

Yes. With "Same as image" each page matches its screenshot; with A4 or Letter each image is scaled to fit and centred.

Are my images uploaded?

No. The PDF is created entirely in your browser.
