Converting images to PDF for research and academic use
Researchers commonly need to convert images to PDF for figure submission, supplementary materials, protocol documentation, and grant applications. This tool converts JPG, PNG, TIFF, and other image formats to PDF entirely in your browser — no file is uploaded to any server, and there is no limit on the number of images or file size (subject to your browser's memory).
Image resolution for publication
Most journals require figures at 300 dpi or higher for print. If your images were captured at lower resolution, converting them to PDF does not increase the underlying resolution — a 72 dpi screen capture at 300 dpi is still a 72 dpi image. Always capture or export figures at the highest resolution available from your instrument or software.
Reordering and combining
This tool allows you to reorder images before converting, making it straightforward to combine multiple figure panels into a single PDF for supplementary material submission. For multi-panel figures, consider whether your journal requires each panel in a separate file or all panels in one combined file — submission guidelines vary significantly.
