Turn screenshots, scans and graphics into a PDF with every pixel kept, on your own device.
PNG is what you get from screenshots, design tools and many scanner apps, and it is lossless: text edges and thin lines stay crisp. This converter keeps it that way. Each PNG becomes a PDF page stored losslessly, so a screenshot of a bank statement, a chat, a chart or a ticket reads exactly as on screen. Transparent areas stay transparent in the PDF and show as white paper in viewers. You can mix in JPG and WEBP images and merge everything into one document; the work happens in your browser without uploading anything.
How to convert PNG to PDF
- Add the PNG files (screenshots, exported slides, scans), then drag them into page order and rotate any that need it.
- Choose “Fit” to make each page the exact size of the screenshot, or A4 or Letter if the PDF will be printed; set a margin if needed.
- Keep “One PDF” to merge, or pick “One PDF per image”, then convert and download.
What happens to quality, size and metadata
PNG pages are stored with lossless compression, the same kind PNG uses itself, so the PDF shows exactly the pixels of your file: no blur around text, no colour shifts. Transparency is kept as a mask, which PDF viewers draw on a white page. The size of the PDF stays close to the PNGs together; it can be a bit larger because PNG and PDF use the compression slightly differently. Large photos saved as PNG make large PDFs; if you need the PDF smaller, save those photos as JPG first (PNG to JPG) or use a JPG to PDF size target, which accepts PNG and compresses it. Text in screenshots is a picture, not selectable text.

PNG PNG is a lossless image format published by the W3C in 1996 and later as ISO/IEC 15948. Every pixel is kept exactly, and it supports full transparency, which makes it ideal for screenshots, logos and text. Photos saved as PNG are usually several times larger than as JPG.
PDF PDF is a page-based document format created in 1993 and an open ISO standard (ISO 32000) since 2008. Each page keeps its exact layout, fonts and images, so it looks the same on every device. A PDF can hold scanned photos, text, vector drawings and forms.

Without this site
Mac: open the PNGs in Preview, select all thumbnails in the sidebar, then File › Print › PDF › Save as PDF; or select them in Finder and use Quick Actions › Create PDF. Windows: select the files, right-click › Print, choose “Microsoft Print to PDF”. iPhone: screenshots can be saved as PDF directly: take a screenshot of a web page in Safari, tap the preview, choose “Full Page” and Done › Save PDF to Files. Android: Google Photos › ⋮ › Print › Save as PDF, one image at a time.
Troubleshooting
- Long screenshots look tiny on A4. A scrolling screenshot is very tall; on A4 it is scaled down to fit. Use “Fit” so the page has the screenshot’s own shape.
- The PDF is larger than expected. PNG photos are big by nature. Convert photos to JPG first, or use a JPG to PDF size page for upload limits.
- A dark or checkered background shows in some viewers. A few viewers draw transparent areas on their own background colour. If that matters, flatten the PNG on white first (PNG to JPG with a white background).
- Text is not searchable. A screenshot is an image; the PDF contains pictures, not text. Use the original document’s “Save as PDF” if you need selectable text.
Questions and answers
How do I convert a PNG to PDF without losing quality?
Use a converter that embeds the PNG losslessly, as this one does. Each page keeps the exact pixels, so text in screenshots stays sharp. Choose “Fit” as the page size if you don’t want the image scaled to a paper format; with A4 or Letter it is scaled to the page, which changes its printed size but not its pixels.
Can I combine PNG and JPG images in one PDF?
Yes. Add PNG, JPG and WEBP files together, arrange them and keep “One PDF”. PNG pages are stored losslessly, JPG pages go in unchanged, and WEBP images are converted to high-quality JPG. The result is one PDF with pages in the order you set.
Does PNG transparency stay in the PDF?
Yes, as a transparency mask. Most PDF viewers draw the page white, so transparent areas look white on screen and in print. A logo with a transparent background therefore appears on white paper, which is usually what you want for printing and sharing.
How do I turn screenshots into a PDF on my phone?
Open this page in your phone’s browser, tap “Add files” and select the screenshots from your gallery. Put them in order and convert: the PDF is saved to Downloads (Files app on iPhone). The screenshots are processed in the browser on the phone and never uploaded.
