How it Works: Browser-Based Compression

Traditional online compression tools require you to upload your images to a remote server, which can be slow and risky for privacy.

This tool uses modern Canvas API and WebAssembly technologies built into your browser to decode, redraw, and compress images directly on your device.

Use Cases

1

Website Performance

Convert large PNG/JPG headers to WebP to reduce file size by 30-70%, significantly improving load times and SEO.

2

Registration Forms

Many systems limit upload size (e.g., under 200KB). Use this tool to fine-tune quality to meet strict requirements.

3

Save Space

Phone photos are often massive (5MB+). Batch compress your backups to save GBs of storage space.

4

Faster Sharing

Sending original photos via email or messaging apps is slow. Compress them first for instant delivery with minimal quality loss.

Frequently Asked Questions

What is WebP and why use it?
WebP is a modern image format by Google. It provides superior lossless and lossy compression for images on the web, often 25-34% smaller than comparable JPEG images.
Why doesn't changing quality affect PNG?
PNG is a "lossless" format. The browser's standard Canvas API uses a fixed compression level for PNGs. To reduce size, consider converting to WebP or JPEG (lossy).
Are my images uploaded?
Absolutely not. All processing happens locally in your browser via JavaScript. You can even use this tool offline.
Can I batch compress?
Currently, we support single file processing to ensure browser stability. Batch processing features are coming soon.
