Your images never leave your device. Everything runs locally — fast and private.
What This Tool Actually Does
This converter builds a PDF from your PNG images using jsPDF, entirely in your browser. Each image becomes one page. Reordering happens through hover-revealed up/down arrows on each thumbnail, not drag-and-drop.
One detail worth knowing before you convert a PNG specifically: every image is embedded as a JPEG, and JPEG has no transparency channel. If your PNG has a transparent background — a logo, an icon, a graphic — that transparency will be flattened to a solid background in the PDF rather than staying see-through. For photos and screenshots without transparency, this has no effect at all.
How to Convert PNG to PDF
- Upload your PNG images. Open the converter above and drop in one or more PNG files, or click to browse.
- Reorder if needed. Hover over a thumbnail and use the up/down arrow buttons to change its position — there's no drag-and-drop reordering.
- Choose layout options. Pick a page size (A4, Letter, or Fit to Image), orientation, and margin.
- Convert to PDF. Click Convert to PDF. Each PNG becomes its own page, scaled and centered based on your settings.
- Download. The finished PDF downloads automatically.
Tool Limitations
- Transparent PNG backgrounds are flattened — not preserved as transparent.
- Reordering is hover-and-click, not drag-and-drop.
- Images are re-encoded as JPEG during embedding, which can affect very fine detail.
- Fit to Image assumes 96 DPI when converting pixel dimensions to a physical page size.

Frequently Asked Questions
Can I convert multiple PNG images to one PDF?+
Yes. Upload several PNG images and the tool combines them into a single PDF, one image per page, in the order shown in the list.
Does converting PNG to PDF keep transparency?+
No. Every image is embedded into the PDF as a JPEG, and JPEG has no alpha channel, so a transparent PNG's see-through areas will be flattened to a solid background instead of staying transparent. This mainly matters for logos or graphics with a transparent background — check the output before relying on it for anything design-sensitive.
Can I reorder my PNGs before converting?+
Yes, but only through hover-revealed up/down arrow buttons on each thumbnail — there is no drag-and-drop reordering.
Can I mix PNG and JPG images in the same PDF?+
Yes. This converter accepts JPG, PNG, and WebP, so you can combine formats in a single batch even on this PNG-focused page.
Can I choose the PDF page size?+
Yes. Choose A4, Letter, or Fit to Image page size, plus portrait or landscape orientation for A4/Letter.
What does "Fit to Image" do?+
It creates a PDF page sized to match each image's own pixel dimensions (assuming 96 DPI), instead of placing it onto a standard A4 or Letter page.
Is the PNG to PDF conversion free?+
Yes. The tool is completely free with no signup, no watermarks, and no upload to any server.
Does converting PNG to PDF reduce image quality?+
Every image is re-encoded as JPEG when it's embedded, which is a lossy format. For photos and screenshots this usually isn't visibly noticeable, but a PNG with sharp edges, transparency, or fine detail can show some change from the original.
Does this tool upload my images to a server?+
No. Images are assembled into a PDF locally in your browser using jsPDF.
Can I use this for screenshots saved as PNG?+
Yes. Combining several screenshots into one PDF is a common use case — add them in order, choose a page size, and convert.
