Why Use Doxad PNG To PDF
Truly Lossless
PNGs are embedded into the PDF without re-encoding — a pixel-for-pixel copy, which matters for screenshots, UI captures, and line art.
Transparency Handled
Alpha channels are preserved in the document; viewers render transparent regions over the page background.
One Page per Image
Pages take each image's exact dimensions, so nothing is scaled, cropped, or padded.
100% Local Processing
Everything runs in your browser with the open-source pdf-lib library — no uploads, ever.
Frequently Asked Questions
Is the conversion really lossless?
+
Yes. PNG data is embedded into the PDF as-is, with no re-compression — the pixels in the PDF are identical to your original file.
What happens to transparent backgrounds?
+
Transparency is preserved inside the PDF. Most viewers display transparent areas over white, matching how the image looks on paper.
Can I combine several PNGs into one PDF?
+
Yes — add as many as you need (up to 15 MB each) and reorder them before converting.
Are my images uploaded to a server?
+
No. The PDF is built locally in your browser; your files never leave your device.
