Image compressor

How to use

1. Add your images. Drag and drop one or many JPG, PNG, WebP or AVIF images, or click to browse and select files from your device.
2. Pick a compression mode. Use the quality slider for manual control, or switch to target-size mode and enter the exact file size in KB you want.
3. Keep or change format. Compress in the original format, or convert to a more efficient format like WebP or AVIF for even smaller files.
4. Compress and download. Run compression locally, review the size saved on each file, then download individually or as a single ZIP.

Features

• Strong encoders. Compress JPG, PNG, WebP and AVIF with MozJPEG and OxiPNG-class encoders that squeeze files smaller than a plain browser export.
• Compress to a target size. Enter an exact target in KB and the compressor finds the quality that hits it, a feature most competitors simply do not offer.
• Batch with before and after. Process many images at once and see the original size, new size and total percentage saved across the whole batch.
• Keep format or convert. Stay in the original format, or convert to WebP or AVIF during compression for the smallest possible files.
• Unlimited and fully private. Unlike TinyPNG, iLoveIMG or Convertio, files never leave your browser, with no upload, no sign-up and no file limits.

When to use it

• Compress a folder of JPG photos so your website loads faster and scores better on page-speed tests.
• Hit an exact upload limit, like squeezing an image under 200KB for a form or job application.
• Reduce PNG screenshots and diagrams so they fit under email or chat attachment caps.
• Batch-compress product photos before adding them to a store, keeping every file consistently small.
• Shrink oversized images for email newsletters so they send quickly and do not get clipped.

Is it private?

All images are compressed locally in your browser and are never uploaded to any server.
