Frequently Asked Questions
What image formats are supported?
We support JPG, PNG, and WebP formats. These cover virtually all common image types used online.
How many images can I resize at once?
You can upload and resize multiple images simultaneously. Practical limits depend on your device memory, but typically 20 to 50 images work smoothly.
Will resizing reduce image quality?
Making images smaller (downscaling) maintains good quality. Enlarging images (upscaling) may reduce sharpness since you are creating pixels that did not exist originally.
What does maintain aspect ratio do?
When enabled, the image proportions stay the same. If you enter only width, height calculates automatically. When disabled, images stretch to exact dimensions you specify.
Are my images uploaded to your servers?
No. All image processing happens entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy.
What are the popular preset sizes for?
Each social media platform has recommended image dimensions for optimal display. Using these presets ensures your images look perfect on each platform without cropping or quality loss.
