Batch Image Converter is a free online tool. Convert between JPG/PNG/WebP/HEIC/BMP freely, batch supported.
After uploading the image, select the target format and click Convert to download it. Supported input formats include PNG, JPEG, WebP, AVIF, BMP, GIF, TIFF, etc., and the output format covers all major image formats. You can upload multiple pictures in batches and convert them to the same format uniformly.
The conversion process is completely done locally in the browser, using Canvas as the intermediate format: first decoding the original image into pixel data, and then encoding it according to the target format. The compression quality can be adjusted for lossy formats (JPEG, WebP lossy mode). Formats that support transparency (PNG, WebP, AVIF) retain the alpha channel.
Suitable for designers to convert material formats between different projects, or solve compatibility issues that cannot be opened in some software. It is also used to batch migrate old format pictures to new formats to save storage space.
