Frequently Asked Questions
What quality setting should I use?
For web images, 70-80% quality is usually optimal - it provides significant file size reduction with minimal visible quality loss. For email attachments, 60-70% works well. For archival purposes, keep it at 90%+.
Is my image uploaded to a server?
No! All compression happens directly in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy.
Why does the file get larger sometimes?
This can happen when compressing already-optimized images or when converting from a more efficient format. PNGs with few colors may actually be more efficient than JPEG. Try the original format if this occurs.
Does compression affect image dimensions?
No, this tool only reduces file size, not dimensions. The width and height remain the same. To resize images, use our Image Resizer tool.
