Dimensions tool

Change image dimensions by exact width and height.

When a form asks for a specific size, use the dimensions tool to crop the source image and export it at the required pixel width and height. It is useful for application photos, ID uploads, certificates, and profile images.

Pixel-perfect output

Enter the exact width and height required by the portal. The canvas output uses those values directly, so the downloaded file has the dimensions you selected.

Crop before resizing

Cropping first avoids stretched faces, cut-off signatures, and wasted blank margins. Use drag crop or numeric crop values for more control.

Choose format and size

Export as JPG, JPEG, PNG, or WebP and combine the dimension setting with a maximum file size or compression percentage.

Common questions

Can I resize to 300x300, 800x600, or any custom size?

Yes. The width and height inputs accept custom pixel values, so you can create square, portrait, or landscape output.

Will the output stretch the image?

The selected crop is drawn into the target dimensions. Crop the important area first to avoid unwanted stretching.

Can I preview the final dimensions?

Yes. The output preview shows the processed image and reports the final pixel dimensions.
