Frequently Asked Questions
How much can I compress an image without losing quality?
For JPEG images, you can typically achieve 50-70% compression with minimal visible quality loss at quality level 80-85. PNG images can be compressed 30-50%. WebP offers the best compression, achieving 25-35% better compression than JPEG at the same quality level.
Is my image data safe when using this tool?
Yes, completely safe. All image compression happens locally in your browser using JavaScript and Canvas API. Your images never leave your device and are not uploaded to any server or stored anywhere.
What image formats are supported?
The compressor supports JPEG/JPG, PNG, and WebP formats. You can compress images in these formats and optionally convert between them during compression for even better results.
Can I compress multiple images at once?
Yes! The tool supports batch compression. Upload multiple images and compress them all with the same quality settings. Download them individually or as a ZIP archive.
What quality setting should I use?
For web use, quality 80-85 is recommended for JPEG (good balance of size and quality). For PNG, quality 80-90 maintains sharp edges. WebP at 80-85 provides excellent results. Use the preview to find your ideal setting.
Will compression affect image resolution or dimensions?
No, compression only reduces file size by optimizing how the image data is stored. The pixel dimensions (width and height) remain unchanged. To change dimensions, use our Image Resizer tool.
