Compress Images Locally Without Upload

Use this tool nowImage compression services typically require uploading your photos to remote servers. For personal photos, sensitive screenshots, or confidential images, this creates unnecessary privacy exposure. JuTasks compresses images entirely in your browser using canvas-based optimization.

Use this tool nowHow it works
How does this tool work locally?
The compression tool uses HTML5 Canvas and browser-image-compression to process your images. When you drop an image, it's decoded in your browser, resized if needed, and re-encoded with optimized quality settings. The compressed result is generated entirely in your browser's memory.
Why is local processing more secure?
Your photos may contain more than you realize: EXIF data with GPS coordinates, camera information, and timestamps. Uploading to compression services means this metadata — and the images themselves — are transmitted and potentially stored. By compressing locally, your images and their metadata stay on your device.
When should you use this tool?
- Compressing photos before sharing
- Reducing image sizes for websites
- Preparing images for email attachments
- Optimizing screenshots for documentation
- Processing personal or sensitive photos
Frequently Asked Questions
How much can I reduce my image size?
Results vary based on the original image. JPG photos typically see 40-70% reduction. PNG screenshots may see 30-50% reduction.
Does compression affect image quality?
Yes, lossy compression trades some visual quality for smaller file size. For most uses, the quality loss is imperceptible.
What image formats are supported?
The compressor supports JPG, PNG, WebP, GIF, and BMP files.
Are my images uploaded to any server?
No. All compression happens in your browser using JavaScript. Your images never leave your device.
