How It Works
Simple steps to get your converted file
Upload your PNG files
Drop one or more .png files. Transparent PNGs — logos, icons, UI screenshots — are all fully supported.
Set the background colour
Choose what fills the transparent areas: white (default), black, or any custom colour. Non-transparent PNGs are unaffected.
Download your PDF
Get a lossless PDF with one page per image. No quality degradation, no watermarks on the free plan.
Transparency, Handled Your Way
Choose a background colour for transparent PNG areas — or go full-bleed. Each image becomes a lossless PDF page.

Built for Lossless Images
Logos, screenshots, icons, UI designs — PNG is the format for pixel-perfect images, and our converter treats it that way.
Transparency Support
PNG transparency (alpha channel) is handled gracefully. Choose a background fill — white, black, or any custom colour — or preserve transparent regions where possible.
Lossless Quality
PNGs are lossless by design, and we keep them that way. Images are embedded at their original pixel resolution with no re-compression applied.
Batch Merge
Upload multiple PNG files and merge them into a single PDF — each image gets its own page. Drag to reorder before converting.
Page Size Control
Fit images to A4, US Letter, or keep the PDF page at the image's native pixel dimensions. Portrait and landscape pages are handled automatically.
Background Fill Options
Set a solid background colour for transparent areas — white for documents, black for dark-mode designs, or any custom hex colour you choose.
PNG & APNG Supported
Works with standard .png files including 24-bit RGBA, 8-bit indexed, and grayscale variants. Animated PNGs (APNG) are converted using the first frame.

Frequently Asked Questions
Everything you need to know about this tool
PDF doesn't natively support full transparency the way PNG does. Our tool lets you choose a background fill colour (white is the default) that replaces transparent regions in the output PDF. You can pick white, black, or any custom hex colour.
No — PNG is a lossless format and we preserve that. Images are embedded into the PDF at their original resolution without re-compression. What you upload is exactly what appears in the PDF.
Yes — upload as many .png files as you like. Each becomes a page in the PDF. You can drag to reorder them before converting. Pro users can combine unlimited images.
The main difference is transparency handling. PNGs can have transparent backgrounds; JPGs cannot. If your image has a transparent background (common for logos and icons), use this tool — it lets you control what colour appears behind your image in the PDF.
Free users can upload PNG files up to 10 MB each, with up to 20 images per batch. Pro users can upload files up to 50 MB each with no batch limit.
