How to Batch Compress Images in 4 Steps
No account, no install. Works on any device in any modern browser.
Drop all your images at once
Select multiple files or drag an entire folder onto FileCrisp. You can mix PNG, JPEG, and WebP in the same batch — the tool handles each format automatically.
No file count limitSet quality once for all files
Adjust the quality slider — 80% is the sweet spot for most web images. This setting applies to every file in the batch equally. You can also choose to convert all to WebP for maximum savings.
80% quality = best size-to-quality ratioCompress all in one click
Hit Compress. FileCrisp processes each file in your browser using WebAssembly. Files are processed in parallel — a batch of 50 images typically finishes in under 30 seconds.
Parallel processing — no queueDownload as ZIP or individually
Once done, download all compressed images as a single ZIP file. The filenames and folder structure are preserved. Or download individual files if you only need a few.
