Free Online Batch Image Converter
When you need to convert a whole folder of images to a single format — say, turning a mix of screenshots and photos into consistent JPGs for a report, or switching a batch of graphics to WebP for a website — doing it one file at a time gets old fast. LovePDFImg's Batch Image Converter lets you drop in any number of JPG, PNG, and WebP files together, choose one target format, and convert everything in a single pass.
Each image is processed individually using the Canvas API: drawn onto a canvas and re-exported in the format you chose, with a quality setting for JPG and WebP outputs and a background color option for any transparency lost when converting to JPG. Once every file is converted, they're bundled into a single ZIP for download. As with all our tools, nothing is uploaded to a server — your images are converted entirely on your device.
