Frequently Asked Questions (FAQ)
Are my images uploaded?
Not at all. All processing happens locally in your browser (using Canvas technology). Your data never leaves your device.
Which formats are supported?
Supports all modern image formats including JPG, PNG, WEBP, GIF. PNG or JPG is recommended for best results.
How is the output quality?
We export using the original resolution of the image, ensuring no quality loss like screenshots. We strive to maintain original clarity.
Why can't I download?
Please ensure you have uploaded an image. For very high-resolution images (like 4K+), the browser might need a few seconds to process.
