PNG to PDF turns PNG images, such as screenshots, exported charts, diagrams, designs and scanned pages saved as PNG, into a PDF. Because PNG is lossless, this tool keeps it that way: with Original quality, each PNG goes into the PDF without any recompression, so small interface text and fine lines look exactly as they did on your screen.
Add up to 100 images (JPG files can be mixed in), order them with the arrows and watch the page preview. Choose Fit to image for pages shaped like each screenshot, or A4 or US Letter with auto, portrait or landscape orientation and an optional margin. Make one combined PDF, handy for a bug report, a tutorial or a design review, or one PDF per image as a ZIP. Transparent areas of a PNG stay transparent and show the white page behind them.
Limits: lossless pages make larger PDFs than JPEG, especially for photos saved as PNG. Choose Smaller file to store the images as JPEG (at most 2000 px on the long side); transparent areas then turn white. Text in a screenshot is part of the picture, so it can't be searched in the PDF without OCR.
