Compress Image

Why use Compress Image?

Compress Image lets you edit and optimise images in seconds, right in your browser — no bulky software to install and nothing uploaded to a server.

• 100% private: files are processed in your browser and never uploaded.
• Completely free, with no account, no watermarks and no usage limits.
• Handles JPEG (.jpg, .jpeg); PNG (.png); WebP (.webp).
• Drag your images onto the dropzone or pick them with the file button. You can add several at once.
• Works on any device — desktop, tablet and phone — and is fully keyboard accessible.

How to use Compress Image

1. Drag your images onto the dropzone or pick them with the file button. You can add several at once.
2. Choose a quality level. Lower quality means a smaller file; the preview shows the trade-off before you commit.
3. Optionally cap the maximum width or height to further reduce size for web use.
4. Click Compress. Everything runs in your browser using the browser-image-compression library — no upload happens.
5. Download each result, or grab them all in a single ZIP.

Examples

• A 4.2 MB phone photo compressed to around 480 KB for a blog post.
• Batch-compressing 20 product images before uploading them to a store.

Supported formats

• JPEG (.jpg, .jpeg)
• PNG (.png)
• WebP (.webp)

Limitations

• JPEG and WebP compression is lossy — very low quality can introduce visible artifacts.
• Extremely large images may be limited by your device's available memory.
• PNG size reduction is more modest than JPEG because PNG is already lossless.
