Quick answer: To convert PNG to PDF, add the PNG files, drag them into order and press Create PDF. This page makes each page the size of its image with no margin; switch to A4 or US Letter for printable pages. PNGs are embedded without recompression, so screenshots and text stay pixel-sharp. Nothing is uploaded.
Screenshots, diagrams, slides and scans saved as PNG become one tidy PDF. Each page takes the exact size of its image, with no white border, and the PNG is embedded as it is, so text stays crisp.

How to convert PNG to PDF
- Choose the PNG files: screenshots, diagrams, slides or scans.
- Drag them into the order the pages should have.
- Keep Same as image for borderless pages, or pick A4 or US Letter for printing.
- Press Create PDF and download it.
Same as image or A4?
- Same as image (default here): every page is exactly the size of its PNG. Ideal for screenshots, slides and diagrams read on screen, and for images of different sizes.
- A4 or US Letter: each image is scaled to fit a printable page with a margin. Choose it for documents that will be printed or sent to an office.
Lossless for screenshots
PNG is a lossless format, and it is placed into the PDF unchanged: the PDF shows exactly the pixels of your screenshot, with no JPG smudges around text. Transparent areas show the white page underneath. The PDF is roughly as big as the PNGs together; for many large screenshots, shrink it afterwards with Compress PDF.
Photos and other formats
For phone photos, JPG to PDF takes JPG, HEIC, WebP and more, with A4 pages by default; iPhone photos also have their own page, HEIC to PDF. To go the other way, PDF to PNG turns pages back into images.
