Frequently Asked Questions

Can I resize an image without losing quality?

When scaling down (making an image smaller), quality is well-preserved. When scaling up, some blurring may occur. For best results, always start with the largest version of your image.

How do I resize an image to a specific file size like 100KB?

Reducing pixel dimensions is the most effective way to reduce file size. For fine-grained control, use the compress tool after resizing to adjust output quality.

What image formats can I resize?

JPG, PNG, WebP, GIF, HEIC, BMP, and AVIF are all supported. The output format matches your original file.

Will resizing change the image's aspect ratio?

Only if you turn off 'Keep aspect ratio'. With it enabled (default), the image is scaled proportionally so it won't look stretched or squished.

Is there a limit on image file size?

Free users can upload images up to 10MB. Pro users up to 50MB, and Ultra users up to 200MB.
