Frequently Asked Questions
Does compression reduce image quality?
Yes, but imperceptibly at 70-80% quality. Modern compression algorithms are smart enough to remove data your eyes can't see. The result looks nearly identical to the original.
What's the difference between PNG and JPG compression?
PNG uses lossless compression (perfect quality, larger files), while JPG uses lossy compression (smaller files, minimal quality loss). For photos, use JPG. For graphics with transparency, use PNG.
Are my images uploaded to your servers?
No. Compression happens entirely in your browser using JavaScript. Your images never leave your device, ensuring 100% privacy.
What's the maximum file size?
Free users can compress images up to 5MB. For larger files, consider using desktop software or splitting the image.
Can I compress multiple images at once?
Currently, you can compress one image at a time to ensure browser performance. Batch compression is planned for future updates.
What quality setting should I use?
For web use: 70-80% is ideal. For print: 85-90%. For thumbnails: 50-60%. Lower quality gives smaller files but more visible artifacts.
