About PNG files
PNG is a lossless image format used for screenshots, diagrams, charts and scanned pages. It keeps text and sharp lines clean.
People convert PNG to PDF to send screenshots as one document, attach diagrams to a report, or meet an upload form that accepts PDF only.
How we convert PNG to PDF
- Page size
- The page matches the image by default. A4, Letter, Legal and A3 are available.
- Placement
- On a fixed page size, the image is fitted inside the page without distortion, centered on white, at 300 DPI.
- Layout options
- Margin and landscape orientation.
- Combine
- Several PNG files can become one multi-page PDF.
- Measured
- A 212 KB PNG became a one-page PDF of 212 KB in about 3.6 seconds.
Common problems and fixes
A wide screenshot looks tiny on a portrait page.
Turn on landscape orientation so the page matches the shape of the screenshot.
The pages are in the wrong order.
Add the images in the order you want them to appear, one image per page.
The image touches the edge of the page.
Set a margin when you choose A4, Letter, Legal or A3.
Hur man konverterar
Upload one or more PNG images.
Optionally pick a page size, margin, or transparency handling in the settings — and with several files, switch on Combine into one PDF and drag rows to set the page order.
Click Convert and download your PDF — one multi-page file with the combine toggle on, or one PDF per image with it off.
Om PNG to PDF
PNG to PDF conversion creates professional documents from PNG images while preserving their unique features including transparency, lossless quality, and sharp edges. PNG's strengths in handling graphics, screenshots, and designs translate perfectly to PDF format.
Unlike JPEG conversion which may alter image data, PNG to PDF embedding preserves the exact pixel-perfect quality of your original images. Transparency in PNG files is maintained in the PDF, allowing for sophisticated document layouts with overlapping elements. This makes PNG-to-PDF ideal for design work, technical documents, and presentations.
Designers compile graphic work into presentation portfolios. Technical writers convert diagrams and screenshots into documentation. Software companies create user guides with clear interface captures. Architects compile plans and drawings into comprehensive packages. Marketing teams assemble branded graphics into shareable documents.
Several PNGs can become one document: switch on Combine into one PDF in the settings panel and every image lands on its own page of a single PDF, in the order shown in the file list — drag rows to reorder before converting — and the whole batch counts as one conversion against your quota. By default each page matches its image's exact pixel dimensions; pick A4, A5, Letter, Legal, or A3 instead to scale the image onto a standard page (aspect ratio preserved, centered), with a Landscape toggle and a millimeter margin setting. A Transparent Areas selector decides what happens to alpha regions: keep the transparency in the PDF for digital viewing, or flatten to white (best for printing) or black.

Så fungerar det
PNG images are embedded with lossless Flate compression — never re-encoded to JPEG — and alpha channels are written as PDF soft masks (SMask), so transparency renders correctly in standard viewers. There is deliberately no quality slider: the embedding is always exact. Optional placement controls scale the image onto a named page (A4, A5, Letter, Legal, A3) with landscape orientation and millimeter margins; the Transparent Areas option can instead flatten alpha onto a white or black background. With Combine into one PDF enabled, all selected PNGs are assembled into one multi-page document in a single job.
