How it works — three steps

How to compress images in 3 simple steps

Drop files in, adjust the dial, download the batch. It works the same for one image or thirty, and takes about a minute.

  1. Step 01

    Add your images

    Drag and drop up to 30 files, click to browse, or paste straight from your clipboard. JPEG, PNG, and WebP up to 50 MB each.

  2. Step 02

    Tune the settings

    Pick a quality level, an output format, and optionally cap dimensions or target an exact file size.

  3. Step 03

    Download and done

    Save files individually or grab the whole batch as one ZIP archive.

Features

A browser-based image optimizer, nothing to install

Everything you expect from a desktop tool — packed into a single page that works on any device, online and offline.

  • 100% private by design

    Compression runs entirely inside your browser using Web Workers. Images never touch a server, so there is nothing to leak.

  • Batch processing

    Drop up to 30 images at once, watch a live progress bar for each file, and grab them individually or as one ZIP.

  • Smart compression

    Set a target file size and the encoder iterates internally until your image fits the budget you need.

  • Resize while compressing

    Cap the longest edge pixel-by-pixel with sensible presets from 640 px up to 2560 px, without leaving the flow.

  • Format conversion

    Keep the original format or convert everything to JPEG, PNG, or WebP with a single switch.

  • Precise quality control

    A real quality slider from 10 to 100 instead of vague presets, so you decide the tradeoff between size and fidelity.
