How do I convert a PUB file to PNG online?

Using LetsConvert, upload your PUB file, select PNG as the output format, choose the desired DPI (e.g., 300 for print quality), and toggle transparency if needed. Click 'Convert' and each page of your Publisher document will be rendered as a separate PNG file. Download the images instantly after processing.

Why should I convert PUB to PNG instead of keeping it as a Publisher file?

PUB files are proprietary to Microsoft Publisher and often render incorrectly without that software. PNG is a universal raster format supported by every browser, social media platform, and image viewer. Converting to PNG makes your publication easy to share by email, embed in websites, or archive without compatibility issues. The trade-off is that the text becomes non-editable, but the visual layout is preserved.

Does PUB to PNG conversion preserve layers, transparency, and vector sharpness?

Conversion flattens all layers into a single raster image, so individual design elements are no longer editable. Vector graphics and text are rasterized, meaning they become pixel-based; however, at high DPI (300+), the output remains visually sharp for screen and print. We honor transparency for objects with alpha channels, so if your PUB file uses transparent backgrounds, the PNG will retain it unless you choose a solid background.
