Batch image compressor

Shrink a whole folder of photos in one go.

Drop in as many images as you want, compress or convert them all, and download one zip. Set an exact target file size instead of guessing at a quality slider. Nothing you upload ever leaves your browser.

Drop images here, or browse files

JPG, PNG, WebP, HEIC-in-browser support varies by device — any image your browser can open

🔒 Runs entirely in your browser — your images are never uploaded anywhere
