How to use Compress Image
- 1Drag and drop one or more images (JPEG, PNG, WebP, etc.) into the upload area.
- 2Choose the compression mode: by quality (slider from 1 to 100) or by target size (100 KB, 500 KB, 1 MB, etc.).
- 3Pick a quick preset (Web, Balanced, High quality, Lossless) or manually adjust the slider.
- 4Optional: change the output format (WebP, JPEG, PNG) to save even more space.
- 5Click the result to show the visual Before/After comparison slider.
- 6Download the compressed image, or in batch mode, download all files as a ZIP.
Tips
- WebP format saves 25–35% more than JPEG at equivalent quality.
- Expert mode (Starter+) unlocks pro codecs: MozJPEG, AVIF, JPEG XL for maximum compression.
- Use target size mode when you have a strict file size constraint (e.g. 200 KB for an online form).
- In batch mode (Starter+), compress up to 20 images at once with a ZIP download.
