Image Compressor

How to use it

For website owners, sellers and marketers who need lighter product photos, banners and blog images — without uploading them anywhere.

1. 01Choose an output format and quality, and a maximum width or height (1920 px suits most websites).
2. 02Drop up to 30 images or choose them from your device; they're compressed one by one straight away.
3. 03Check the before and after size of each image. If a version comes out larger, you'll see a warning.
4. 04Save images one at a time, or download them all as a ZIP.

How results are worked out

• Images are decoded and re-encoded by your own browser using a canvas — nothing is uploaded to a server.
• Resizing keeps the aspect ratio and never enlarges a smaller image.
• Phone photos are rotated upright using their orientation tag before resizing, so nothing ends up sideways.
• Re-encoding removes EXIF metadata, including any GPS location the camera stored.
• With 'Keep the original if it's already smaller' on, the ZIP uses the original file whenever compression would make it bigger.

Limitations

• HEIC/HEIF photos can't be opened by most browsers — export them as JPEG first.
• Animated GIFs become a single still image. SVGs aren't processed (they're already vector files).
• WebP or AVIF output depends on your browser; if it can't create a format, the tool tells you which format was used instead.
• Very large images may be slow on older phones because all processing happens on your device.
