Frequently Asked Questions (FAQ)

What is the difference between resizing and cropping?

Resizing changes the actual dimensions of the entire image (e.g., shrinking a 2000px wide photo to 1000px). Cropping cuts out a specific part of the image, removing the rest. Our tool allows you to do both.

Can I make an image larger (upscale)?

Yes, you can enter dimensions larger than the original. However, please note that upscaling bitmap images (like JPG or PNG) may result in pixelation or blurriness, as the computer has to "guess" the new pixels.

What formats are supported?

We support all major web formats including JPG, JPEG, PNG, and WebP.
