Higher keeps more detail. Lower usually produces smaller files.

Leave width and height empty to keep the original size. When both are set, images scale down to fit and keep their aspect ratio.

WebP stays the default. Use original format to preserve each upload type, or specified format for a consistent handoff.

Max file size: 50 MB

How to compress images

The flow stays deliberately short: pick files, choose the output mode, compress with resize rules, then download one file or a ZIP.

01

Upload images

Select one or more local image files and keep the entry action impossible to miss.

02

Compress and resize

Apply one quality setting and one resize rule across the queue so the batch stays predictable and easy to review.

03

Download results

Grab individual files or download every compressed result as one ZIP without leaving the tool flow.

Three output modes

Keep original formats, force one specified format, or retain the WebP default before users add files.

Batch-oriented queue

The same settings apply across the batch, so compressing an entire folder still feels readable and controlled.

Local-first default flow

The default compression route runs in the browser, which keeps the privacy boundary easy to understand.

Frequently asked

Short answers to the questions people usually have before compressing production image assets.

Can I compress multiple images at once?

Yes. The queue is built for multi-file work, and ready files can be downloaded individually or as one ZIP.

Does resizing keep the aspect ratio?

Yes. Max width and max height act as a bounding box, and images only scale down to fit within it.

Will the file type always change?

No. Maintain original format preserves each upload type when the browser can export it, specified format forces PNG, JPEG, or WebP, and WebP remains the default.

Does this tool upload my images first?

The default compression flow is designed to run in the browser with Canvas APIs, so users can reduce file size without depending on a server upload.
