How to convert PNG to PDF
Add your PNGs
Drop PNG files into the box, tap to choose them, or paste a screenshot with Ctrl+V.
Order and page size
Reorder pages with the arrows and choose Fit to image, A4 or Letter.
Convert and download
Click Convert to PDF and save the document.
Best for screenshots, diagrams and designs
PNG is the format of choice for screenshots, charts, UI mockups and documents saved losslessly. Turning them into a PDF lets you send one ordered document for a bug report, design review, course assignment or invoice bundle — and the recipient can open it on any device without an image viewer.
Lossless from PNG to PDF
PDF supports lossless Flate compression — the same DEFLATE algorithm PNG uses — so Fylo carries every pixel across without artefacts. That keeps small text crisp, which matters for screenshots and forms.
The trade-off is size: large photographic PNGs stay large inside the PDF. If size matters more than pixel-perfect accuracy, convert to JPG first or run the result through Compress PDF.

Frequently asked questions
What happens to PNG transparency in a PDF?
PDF pages have a white background, so transparent areas show as white when viewed or printed. The image keeps its alpha channel inside the PDF.
Can I mix PNG and JPG files in one PDF?
Yes. Fylo accepts both — plus WebP, GIF, HEIC and other images, which are converted on the fly.
Is there a page limit?
No fixed limit. Very large batches depend on your device's memory; a hundred or more screenshots are typically fine on a laptop.
How do I make the PDF smaller?
Run it through Compress PDF using the Strong setting, which re-encodes pages as JPG.
Are my files uploaded to a server?
No. PNG to PDF runs entirely in your browser — your files are processed on your own device and never sent anywhere. Once the page has loaded, it even keeps working if your connection drops.
