PNG files are everywhere: screenshots, design exports, diagrams with transparent backgrounds. When you need to share or archive them as a PDF, most online converters force you to upload your files to a remote server. With freeimagetopdf.app, you can convert PNG to PDF free directly inside your browser. Nothing is uploaded, nothing leaves your device, and the result is a clean, high-quality PDF you can use anywhere.
PNG is the go-to format for screenshots, UI mockups, graphic designs, and any image where you need crisp edges or transparency. But PDFs are the universal standard for sharing documents across platforms. Converting PNG to PDF lets you bundle multiple screenshots into a single file, prepare design proofs for clients, or archive graphics in a format that prints reliably on any device. A PDF wrapping your PNGs preserves their quality while giving you a portable, professional-looking document.
When you drop a PNG into freeimagetopdf.app, the converter embeds the image data losslessly into the PDF container. There is no re-encoding, no compression artifacts, and no quality loss. The pixels in your output PDF are identical to the pixels in your source PNG. This makes the tool especially useful for screenshots of text, technical diagrams, and any graphic where every pixel matters. Because everything runs locally through JavaScript and the Canvas API, your files stay on your machine the entire time.
Yes. PNG supports an alpha channel that defines transparent and semi-transparent regions. When freeimagetopdf.app converts your PNG to PDF, that alpha channel is retained. If you open the resulting PDF in any modern viewer, areas that were transparent in the PNG will remain transparent in the PDF. This is critical for logos, icons, and design exports that rely on transparency to layer correctly over other content.
PNG is a lossless format. It stores every pixel without discarding data, and it often includes a full alpha channel for transparency. A JPG of the same image dimensions, by contrast, uses lossy compression that throws away detail the human eye is unlikely to notice. The result is that PNG files are typically two to ten times larger than equivalent JPGs, and that size difference carries directly into the PDF. If you are converting a batch of photographs and file size matters, JPG is usually the better source format. But if you need pixel-perfect fidelity or transparency, PNG is worth the extra kilobytes.
Choose PNG when your images contain text, sharp edges, transparency, or flat-color graphics. Screenshots, diagrams, logos, and UI exports all benefit from PNG's lossless encoding. Choose JPG when you are working with photographs or complex natural-scene images where lossy compression is acceptable and smaller file size is a priority. freeimagetopdf.app supports both formats (and WebP too), so you can mix PNG and JPG files in the same PDF if you like. Drag in your images, reorder them, pick a page size, and generate. The whole process takes seconds.
First, open freeimagetopdf.app in any modern browser. Second, drag and drop your PNG files onto the page, or tap to browse and select them. You can add as many images as you need. Third, choose your page size and orientation, then click Generate PDF. Your PDF downloads instantly. No account, no watermark, no waiting for a server.
Open freeimagetopdf.app, drag and drop your PNG files onto the page, adjust page size and orientation if needed, then click Generate PDF. Everything runs in your browser — no upload required.
Yes. freeimagetopdf.app embeds your PNG losslessly into the PDF, preserving alpha transparency exactly as it appears in the original file. Transparent regions stay transparent in the output.
PNG is a lossless format that retains every pixel and often includes an alpha channel, so it stores more data than lossy JPG. The resulting PDF inherits that larger data payload. If file size is a concern and you do not need transparency, consider using JPG source images instead.
Yes. Drop as many PNG files as you need and they will be combined into a single PDF with one image per page. You can drag to reorder and use the rotate buttons to adjust orientation before generating.
Use PNG when you need transparency, sharp text, or pixel-perfect screenshots. Use JPG for photographs where smaller file size matters more than lossless quality. freeimagetopdf.app handles both formats seamlessly.
