PNG to PDF について
PNG files carry their pixels without loss, and this conversion keeps it that way. Each PNG is decoded and written into the PDF with lossless compression, so screenshots of code, spreadsheets, chat threads and user interfaces stay razor sharp, and a diagram's thin lines and flat colours come through untouched. Transparent areas remain transparent inside the PDF, which shows them over the white page; a logo with a soft shadow keeps its smooth edge instead of picking up a black or checkered box.
Screenshots rarely match a paper size, so the page layout matters more here than with photos. Same as image makes each page exactly the screenshot's shape at 96 pixels per inch, which reads well on screen and avoids white borders, though a wide 2560-pixel capture becomes a page more than 26 inches across when printed. A4 or Letter with Fit keeps a uniform document for printing or for a portal that checks the paper size, and Auto orientation turns pages landscape for wide captures.
Typical jobs are bundling a sequence of screenshots for a support ticket or a how-to guide, collecting scanned forms saved as PNG into one file, and handing in diagrams as a single attachment. Because nothing is recompressed, a PDF of many large PNGs is about as heavy as the PNGs themselves; run it through a PDF compressor afterwards if an email size limit gets in the way. Any other image format can be mixed in, and JPG, WebP or HEIC files dropped alongside are handled too.
プライバシー
The PNG files are read in this tab and the PDF is assembled by pdf-lib in a Web Worker on your device, so the screenshots, which often show private messages or account details, are never uploaded anywhere. The page doesn't keep a copy after you close it.
