Screenshots and graphics, bound into a document
PNG is the format of the screen: screenshots, UI mock-ups, charts exported from analytics dashboards, diagrams, and any graphic where text must stay razor-sharp. But screens are fleeting and folders of screenshots are chaos. Binding PNGs into a PDF turns scattered captures into something durable — a bug report with reproducible steps, a design review pack, documentation of a configuration before you change it, or evidence of an online transaction. This converter builds that PDF in your browser, preserving the pixel-perfect crispness PNGs are loved for.
How to convert PNG to PDF
- Drop one or more PNG files into the tool.
- Arrange by add-order — thumbnails show the page sequence; remove any with ✕.
- Choose the layout: “Fit to image” keeps every pixel edge-to-edge, A4/Letter formats it for paper.
- Click Convert to PDF.
The screenshot-to-PDF sweet spot: “Fit to image”
For screen captures, the Fit to image page size is usually the right choice. Each PDF page adopts the exact dimensions of its PNG, so a 1920×1080 screenshot becomes a 1920×1080 page — no scaling, no margins, no resampling blur on fine UI text. The result reads like a slideshow of your screens at native sharpness. Choose A4 instead when the document is destined for paper or must sit alongside other A4 paperwork; the tool then scales proportionally and centres each image within your margin.
About transparency
PNG supports transparent backgrounds; paper doesn't. Where a PNG has transparency, the PDF page shows it against white, which is what you want for logos and diagrams 99% of the time. If a graphic was designed for a dark background and looks washed out on white, flatten it onto its intended background colour in an editor first — or use our Add Image Border / Photo Filters tools to prepare it.
Workflows where this tool earns its keep
- Bug reports: sequence the screenshots of each step, convert, attach one file to the ticket.
- Compliance and audits: capture settings screens before/after a change and archive the dated PDF.
- Design hand-off: a paged PDF of mock-ups is friendlier for sign-off than a zip of files.
- Receipts of digital life: order confirmations, transfers and bookings — screenshot, convert, file away.
Crisp in, crisp out — with the order, permanence and portability that loose PNG files never have.

Frequently asked questions
Why do my screenshots look slightly soft on A4 pages?
A4 mode scales the image to fit the paper size, which resamples pixels. For native sharpness choose “Fit to image” — each page then matches the PNG's exact dimensions and UI text stays crisp.
What happens to transparent areas of my PNG?
They appear white in the PDF, as if printed on paper. If the graphic needs a dark or coloured backdrop, flatten it onto that colour before converting.
Can I mix PNGs with JPGs in one document?
This focused page accepts PNGs only. For mixed batches use the Images to PDF tool — same engine, open input filter.
Are very tall screenshots (full-page captures) supported?
Yes. In “Fit to image” mode the PDF page simply becomes as tall as the capture. In A4 mode a very tall image is scaled down to fit one page — for readability, consider splitting extremely long captures first.
