Frequently Asked Questions
Are my private photos uploaded to any external server?
No, never. The entire image editing, compression, and conversion pipeline runs 100% client-side in your web browser. No image data is ever uploaded to our servers or third parties.
How do I compress an image to a specific KB target size?
Under the export options in the right-hand panel, check the "Compress to target size" box, input your target in KB (e.g., 200 KB), and click "Find best quality for this size". Our algorithm finds the highest image quality that stays within your limit.
What image formats can I upload and download?
You can upload JPG, JPEG, PNG, WebP, GIF, and AVIF images. You can export and download your finished image as high-resolution PNG, JPG, or modern WebP format.
Will resizing or converting reduce my image clarity?
You have full control. For maximum quality, export as PNG or Lossless WebP. For smaller web file sizes, you can preview the estimated size before downloading to achieve the perfect balance of visual clarity and file size.
