Question 1

Can I resize images without losing quality?

Accepted Answer

Yes. When scaling down, we use high-quality bicubic resampling. We also preserve your original image's aspect ratio by default.

Question 2

What image formats are supported?

Accepted Answer

JPG/JPEG, PNG, and WebP are fully supported. The output preserves the original format.

Question 3

Will my files be uploaded to a server?

Accepted Answer

No. All resizing happens directly in your browser using the Canvas API. Your images never leave your device.

Question 4

Can I resize to a specific aspect ratio?

Accepted Answer

Yes. Enable "Lock aspect ratio" to resize proportionally, or uncheck it to set exact width and height independently.

Question 5

What is the maximum image size?

Accepted Answer

You can resize images up to 20MB. Output canvas is limited to 16384×16384 pixels (browser canvas limit).
