Frequently Asked Questions
What quality setting should I use?
For web use, 70-85% offers a good balance between quality and file size. For print or professional use, use 90-100%. For thumbnails or previews, 50-70% is sufficient. Experiment with the slider to find your ideal balance.
Will compression reduce image quality?
Yes, compression involves some quality loss, but it's often imperceptible at higher quality settings (70%+). The preview lets you check quality before downloading. Lower settings will show visible artifacts.
What image formats are supported?
This tool supports JPG/JPEG, PNG, and WEBP formats for input. The compressed output is saved as JPEG for maximum compatibility and compression efficiency.
Are my images uploaded to a server?
No. All image compression happens locally in your browser using HTML5 Canvas API. Your images never leave your device, ensuring complete privacy and security.
Can I compress multiple images at once?
Currently, this tool processes one image at a time. After downloading your compressed image, click "Upload New Image" to compress another photo with the same or different quality settings.
