Frequently Asked Questions
How much can I reduce the file size?
Typical JPEG compression at 80% quality reduces file size by 40-70% with minimal visible quality loss. Lower quality settings can achieve 80-90% reduction, but artifacts may become noticeable.
Are my images uploaded to a server?
No. All compression happens locally in your browser using the HTML5 Canvas API. Your images never leave your device and are not stored or transmitted anywhere.
What image formats are supported?
The tool accepts JPEG, PNG, WebP, GIF, BMP, and most browser-supported image formats as input. Output is JPEG format for optimal compression.
Can I compress images without losing quality?
At 90-100% quality, the compression is nearly lossless — the file size reduction is smaller but quality is virtually identical to the original. For most web use, 75-85% quality provides an excellent balance.
