Frequently Asked Questions
Will cropping reduce the image quality?
No! Cropping simply trims unwanted outer pixels from your image without re-compressing the selected pixels unless you lower the export quality setting.

Yes! We provide built-in aspect ratio presets for 1:1 (Instagram/Avatar), 16:9 (YouTube/Banner), 9:16 (Stories/Reels), 4:3, and 3:2.
Is my photo uploaded to your server?
No! ConverterMaster processes all images 100% locally in your web browser using HTML5 Canvas. Your photo is never sent to any server.
