Compress up to 50 JPG, PNG, or WebP images at once and download every result together as a ZIP — entirely in your browser, with a summary of exactly how much space you saved.
What is the Bulk Image Compressor?
The Bulk Image Compressor shrinks a whole batch of images in one pass, right in your browser tab. Drop in up to 50 JPG, PNG, or WebP files, set a single quality level, and every image is compressed using the same settings — no need to process files one at a time. Each row in the results table shows the original size, the compressed size, and the percentage saved, so you can see exactly what happened to every file. Once everything is done, a summary panel totals the original size, the compressed size, the overall bytes and percentage saved, and the average compression ratio across the whole batch. Because nothing is uploaded to a server, it works on large batches of private photos, product images, or design assets without any privacy concerns, and every result can be downloaded individually or all together as a single ZIP file.
