Free online bulk image compressor
If you need to compress multiple images online, Bulk Image Compressor provides a convenient way to process a complete group of files at once. Instead of opening a separate image compressor for every photograph, you can select multiple images and apply the same target file-size workflow to the entire batch.
You can use the tool as a bulk JPG compressor, bulk PNG compressor or WebP compressor depending on the output format you choose. It can help reduce image file size before publishing images to websites, uploading product photos, sharing files or preparing digital assets.
Reduce image file size without complicated software
Traditional desktop image optimization software can be useful, but it may require installation and individual file processing. An online bulk image compressor simplifies this workflow by allowing multiple images to be selected together and processed directly in a modern browser.
Choose a target such as 100 KB, 200 KB or 500 KB, select the preferred output format, review the resulting file sizes and download the optimized images. The actual output can vary by image because photographs and graphics respond differently to compression.
