Built for the pixel-perfect stuff
Sharp edges, no mush
PNG is a lossless format, and Penstead keeps it that way — the pixels are embedded exactly as they are, so screenshots stay crisp and thin lines don’t turn fuzzy. It’s the right choice for a UI mockup, a wiring diagram, or a chart you need to hand over as a real document.
- Screenshots stay pixel-sharp
- Diagram lines and small text stay clean
- Full resolution, no downscaling
- One PNG makes a one-page PDF
Transparency, and a whole set at once
A PDF page isn’t see-through, so any transparent areas in your PNG — the empty corners around a logo, say — sit on a plain white page, with no surprise black boxes. Each PNG becomes its own page, and you can convert several and use Merge to gather them into one PDF.
- Transparent areas land on clean white
- Convert a batch, then merge into one
- Identical output on phone or laptop

PNG to PDF questions
Is my PNG uploaded anywhere?
No. The image is embedded into the PDF inside your browser, so it stays on your device the entire time. That’s ideal for a screenshot of something private, like a dashboard or a message thread.
Is it free, and is there a watermark?
Yes — free, no login, and no watermark. You get just your image on a clean page, with no page limits.
What happens to transparent parts of my PNG?
A PDF page has a solid background, so transparent regions are placed on a white page. That matches how you’d want it to look when printed or shared.
Will the image lose quality?
No. PNG is lossless and Penstead embeds it at full resolution without re-compressing, so fine lines and small text stay sharp in the PDF.
Can I put several PNGs into one PDF?
Each PNG converts to its own one-page PDF. To combine a set — a few screenshots in a row, for example — convert each, then open Merge to order them into a single file.
About converting PNG to PDF
PNG is the format screenshots, diagrams, and exported charts usually land in, because it’s lossless and keeps sharp edges and text crisp. The trouble is that a loose .png is awkward to send as documentation — it opens in an image viewer, prints at unpredictable sizes, and can’t hold a set of related images together. Turning it into a PDF gives you a fixed page that everyone opens the same way, prints cleanly, and reads as a deliverable rather than a stray image.
Penstead keeps the PNG’s lossless quality intact and does the conversion without uploading a thing — the image is embedded into the PDF right in your browser, which matters when the screenshot shows something you’d rather not put on a stranger’s server. From there the PDF opens in the editor, so you can mark it up, add a caption, or merge several screenshots into one document before sharing it.
