Bulk Image Compressor

Compress up to 1000 images at once with our bulk image compressor. Perfect for optimizing entire photo libraries or web asset collections.

Up to 1,000 images in one go. Large batches take a moment because your own machine is doing the work, which is also why nothing is uploaded.

How it works

1
Add your files
Drop JPEG, JPEG, PNG or WebP files on the page, or pick them from your device. Up to 1,000 at once.
2
Set quality and size
The output is WebP. Choose a preset, or open Settings to set quality, dimensions or a target file size.
3
Download
Take files one at a time or the whole batch as a ZIP. Everything stays on your device.

Nothing is uploaded: Every step runs in your browser. Your images never touch a server, ours or anyone else's.
No waiting on a queue: There is no upload and no download, so a file is done in the time it takes your machine to redraw it.
No limits and no watermarks: Up to 1,000 files in one batch, any size your browser can open, and the output is only your image.
Works on any device: Phone, tablet or desktop, in any modern browser. Nothing to install and no account to make.
Three formats, both directions: PNG, JPEG and WebP in, and any of them out. Convert while you compress if the format should change.
One ZIP at the end: Download files one at a time or take the whole batch as a single ZIP.
