Batch Image Compressor
Drop dozens of images, set quality and max width once, compress them all — and download everything as a ZIP.
Bulk compression for real workflows
E-commerce sellers compress product photos before uploading to marketplaces; bloggers shrink an entire post's images in one pass; developers optimise a folder of assets; students squeeze a photo-heavy assignment under an upload limit. Same quality controls as the single-image tools, applied to every file at once — with a before/after summary at the end.
Frequently asked questions
Does compressing reduce image dimensions?
Only if the image is wider than your max-width setting — oversized images are scaled down to it (aspect ratio preserved), which is where the biggest savings come from. Images already narrower stay pixel-identical in size.
Are the images uploaded?
No — every image is compressed on your own device, and the ZIP is assembled in your browser. Nothing touches a server.
