💬 Frequently Asked Questions
Got questions about Image Compressor? Here are the most common answers.
Will compressing my photo reduce its visual quality?▼
Our intelligent canvas compressor removes redundant metadata and applies perceptually lossless quantization. At 75-80% quality, files become 60-80% smaller with virtually indistinguishable visual difference.
Are my private photos uploaded to a cloud server?▼
No. All image compression runs 100% locally inside your browser sandbox using the HTML5 Canvas API. Your pictures never leave your computer or phone.
Does this compressor support transparent PNGs?▼
Yes. When you select PNG or Auto format, transparency channels (alpha channel) are preserved without adding black backgrounds.
