PNG to PDF

About this tool

PNG to PDF bundles your PNG screenshots, design exports, and graphics into a single multi-page PDF document — entirely in the browser, with no server upload. It is the lossless counterpart to JPG to PDF: PNG pixel data is embedded with lossless compression, so the images keep their original quality with no JPEG artefacts. By default each page is sized to fit its image with no margin, and you can switch to A4, US Letter, or A3 pages with Auto, Portrait, or Landscape orientation and a 0–100 point margin. The result is a clean document that is ideal for packaging design assets, sharing UI screenshots with stakeholders, bundling infographics for a report, or sending multiple graphics to a client as one organised file. Drag the thumbnails to set page order before converting, and portrait, landscape, and mixed-orientation images work in the same batch.

Why use it

• Lossless PNG Quality in the Output PDF: PNG images are embedded with lossless compression, so fine lines, crisp icons, and screenshots appear exactly as they were exported.

• Mixed Orientations Supported: Portrait and landscape PNGs can coexist in the same PDF — each page is sized to its source image automatically.

• Drag-to-Reorder Before Conversion: Arrange pages visually using thumbnail drag handles so the final document reads in the right order.

• 100% In-Browser — No Server Upload: Your PNGs never leave your device — ideal for proprietary design files, sensitive screenshots, or confidential infographics.

• Ideal for Design and UI Assets: Package Figma exports, wireframes, and style-guide screenshots into a single PDF for client review or handoff.

• Free with No Signup: Convert as many PNGs as you need without an account, subscription, or watermark on the output.

How to use

1. Click the upload area or drag your PNG files into the PNG to PDF panel.
2. Add as many PNGs as you need — each becomes one page in the output PDF.
3. Drag image thumbnails to set the correct page order before converting.
4. Remove any image added by mistake using the delete button on its thumbnail.
5. Click Create PDF and let the browser assemble the document in seconds.
6. Download the PDF — no data is transmitted, all processing stays on your device.

When it helps

• When packaging a set of UI wireframe PNGs into a single PDF for a stakeholder presentation.
• When sending multiple infographic exports to a client as one organised document instead of a file dump.
• When compiling screenshot evidence for a bug report or QA review into a PDF.
• When bundling exported chart PNGs from a spreadsheet tool into a single shareable report.
• When submitting a portfolio of design work as a PDF and your files are in PNG format.
• When combining logo variants and brand assets into a single reference PDF for a brand guide.

Examples

Tips

• Name your PNG files with numeric prefixes (01-intro.png, 02-hero.png) so they load in the right order and minimise the need for manual dragging.
• If output file size is a concern, run the resulting PDF through the PDF Compress tool to reduce embedded image overhead.
• For design handoffs, export all Figma or Sketch frames as PNG and convert them here to produce a single reviewable PDF.
• If your PNGs contain transparency that matters visually, place them on a white background in your design tool before exporting.
• For very large PNG files, resize them in an image editor to 72–150 DPI before converting to keep the PDF at a manageable size.

Frequently Asked Questions

Glossary

PNG

Portable Network Graphics — a lossless raster format commonly used for screenshots, design exports, and graphics with transparency.

Raster PDF

A PDF where pages consist of embedded pixel images rather than vector paths or text layers.

Lossless

A property of image encoding where no pixel data is discarded during compression, maintaining exact visual fidelity.

Client-Side Processing

Computation that runs in the browser rather than on a remote server, keeping data private and avoiding upload delays.

Page Sizing

Automatically matching a PDF page's dimensions to the source image's pixel width and height.

Alpha Channel

The transparency layer in a PNG image; this data determines which pixels are fully or partially transparent.
