Why Use Our Image Compressor?
Local compression, total privacy
Unlike most online tools, we compress your images right in your browser using the Canvas API. Nothing is ever uploaded to any server. Open DevTools → Network and see for yourself.
Compress without losing quality
At 80% quality, most JPEG images show no visible degradation while achieving 50–70% file size reduction. You can fine-tune the slider for your specific needs.
Supports all major formats
Compress JPEG, PNG, WebP, and GIF. You can also convert between formats — e.g., PNG to WebP — for even smaller output files.
Works everywhere, even offline
This tool runs on standard browser APIs. Once the page loads, you can disconnect from the internet and still compress images.
When Should You Compress Images?
Large images are the single biggest cause of slow websites and failed email attachments. Here are the most common scenarios where image compression makes a real difference:
- ✓Website images — Google penalizes slow-loading pages. Compress images to keep your Core Web Vitals score high.
- ✓Email attachments — most email providers reject attachments over 25 MB. Compress photos before sending.
- ✓Social media — Instagram, Twitter, and LinkedIn all re-compress uploaded images anyway. Pre-compressing gives you better control over quality.
- ✓Cloud storage — reduce storage costs by compressing photos before uploading to Google Drive, Dropbox, or iCloud.
- ✓Confidential documents containing images — because our tool never uploads files, it's safe for sensitive or classified content.
