Process Hundreds of Images at Once
Instead of uploading, compressing, and downloading one image at a time, batch compression lets you process your entire image library in a single operation.
Download Everything as a Single ZIP
Click Download All (ZIP) to get every compressed image in one archive — keeping your original filenames and folder structure intact. No zipping manually.
See Stats for Every File
After compression, the tool shows the original size, compressed size, and percentage reduction for every file in your batch — so you know exactly how much you saved.
Mix Formats in One Batch
Compress JPGs, PNGs, and WebPs together in a single batch. Each format is compressed optimally — JPGs with JPEG encoding, PNGs with palette quantisation.
Who Uses Batch Image Compression?
E-commerce managers use batch compression to prepare hundreds of product images for Shopify or WooCommerce stores. Uncompressed product photos can slow down category pages significantly — batch compressing your entire catalogue before uploading makes a measurable difference to page load times and conversion rates.
Bloggers and content creators batch compress images before uploading to WordPress or their CMS. A single blog post typically has 5-15 images — compressing them all takes seconds with batch upload, versus minutes doing them individually.
Web developers and agencies use batch compression as part of their pre-launch checklist. Compressing all images on a site before launch is one of the fastest wins for improving PageSpeed and Core Web Vitals scores.
After compressing your images, you might also want to remove backgrounds from product photos for a professional, marketplace-ready finish.
