Drop PNG images, download one PDF. Each image becomes its own page, pages follow the order the files arrive in, and a single PNG makes a single-page document.
Built for screenshots and diagrams. PNG is what screens produce: screenshots, exported charts, scanned line drawings, whiteboard captures. This tool binds a set of them into one file that email attachments and printers treat kindly.
Lossless in, lossless in the PDF. PNG embeds without re-encoding, so text in a screenshot stays as sharp in the PDF as it was on screen. Transparency renders on white, as paper would have done anyway.
Pages are sized to the images. No A4 squeeze and no margins: an 1170×2532 phone screenshot becomes an 1170×2532 page. Print menus handle paper-fitting better than a converter guessing at your paper size.
Mixing photos in? The JPG to PDF tool takes JPG and PNG together; this door exists for the pure-PNG job, which is most often screenshots bound into evidence, a guide or handover notes.
Pages follow the order the files arrive in; for a different order, number the filenames (01, 02, 03) and select them together.
