PNGPDFPNG to PDF Converter
Screenshots, scans, receipts and diagrams arrive as PNGs and have to be sent as a PDF. BizTray does that conversion on your own machine: drop in one image or three hundred, choose whether you want a PDF each or a single merged document, and get files back with nothing uploaded and nothing stamped across them.
Drop in your files — PDFs land in the folder you pick, named after the images they came from.
Why convert
Why convert PNG to PDF?
PNG is a screen format. It is excellent at sharp edges, flat colour and transparency, which is exactly why screenshots and exported diagrams use it — and exactly why it travels badly. A PDF has pages, a fixed physical size, and opens the same way on every machine that receives it.
- You have twelve screenshots of an issue and the person who needs them wants one document, in order, not twelve attachments.
- A form, a portal or an application will only accept PDF, and everything you have is a PNG export.
- You scanned a stack of receipts to PNG and want one PDF per receipt to file, or one PDF for the whole month.
- You want the images to keep a fixed page size so nobody opens them at 400% zoom and reads them out of order.
How it works
Convert PNG to PDF in a few clicks
- 1
Open Image to PDF
Pick the Image to PDF tool from the BizTray tray menu. Nothing downloads first — this conversion is built in and works with the network off.
- 2
Drop in your PNGs
Drag one file, a selection, or a whole folder onto the window. There is no file-size ceiling and no cap on how many you add at once.
- 3
One PDF each, or one merged
Choose a PDF per image, or merge everything into a single document and drag the thumbnails into the order you want them read.
- 4
Convert and check the folder
Pick where the output goes and convert. The PDFs appear beside your chosen folder immediately — no queue, no email, no account.
The details
PNG to PDF, at a glance
- Input
- PNG, including 8-bit and 16-bit, with or without an alpha channel
- Transparency
- PDF pages have no alpha, so transparent areas are composited onto white — the safe default for anything you intend to print or send
- Output
- One PDF per image, or a single merged PDF in an order you set
- Page size
- Matched to the image, or fitted to A4/Letter with the aspect ratio preserved
- Rotation
- EXIF orientation is read and honoured, so nothing lands sideways
- Limits
- No file-size cap, no page cap, no daily quota, no watermark
- Engine download
- None — this path is built in and works fully offline
