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.
This is especially useful for standardizing a mixed-format photo library, preparing a batch of assets for a website that requires a specific format, or converting a folder of downloaded images before archiving or sharing them.

Why Choose LovePDFImg for Batch Image Conversion?
iLoveIMG, CloudConvert, and similar tools all offer batch conversion, typically by uploading every file to a server. LovePDFImg processes each image in your browser using the Canvas API, so nothing ever leaves your device. There's no account requirement, no daily cap on usage, and the output has no added watermark.
Technical Details
Each file in the batch goes through the same conversion pipeline as our single-image converters - drawn onto a canvas and re-exported at the target format's native encoding, whether that's JPG's lossy compression, PNG's lossless compression, or WebP's more efficient algorithm. Processing files individually rather than all at once keeps memory usage manageable even for larger batches, and results are collected into a ZIP archive only after every file has finished converting.
