Frequently Asked Questions
Is my image data safe?
Yes! All image processing happens entirely in your browser. Your images never get uploaded to any server.
What's the difference between JPG and PNG compression?
JPG uses lossy compression (some quality is lost), while PNG uses lossless compression. JPG is better for photos, PNG is better for graphics with transparency.
What quality level should I use?
For web use, 70-85% quality provides a good balance between file size and visual quality. Higher values preserve more quality but result in larger files.
Can I compress multiple images at once?
Currently, the tool processes one image at a time. Simply compress each image and download the results individually.
