Frequently Asked Questions
What image formats are supported?
PNG, JPG, JPEG, WebP, GIF, and BMP. Output is always JPEG.
Is there a maximum file size?
Images up to 25MB are supported. Everything is processed on your device, so very large images take longer on older phones.
Does resizing affect image quality?
Reducing dimensions reduces file size. The quality slider (1-100) controls JPEG compression independently of dimensions.
Are my images uploaded anywhere?
No — all processing is done entirely in your browser. Your images never leave your device.
What does the quality slider do?
Lower quality = smaller file size with more compression artifacts. 80-90% is ideal for web use.
