Resize Settings
Choose how you want to resize your images. ByteTony preserves the image shape by default and never crops or stretches an image without your explicit choice.

With aspect ratio lock enabled, the second dimension may change automatically so the image keeps its original shape.
Aspect ratio protection is off. Using unrelated width and height values can stretch or squash the image.
px
Height is calculated automatically to preserve the original aspect ratio.
px
Width is calculated automatically to preserve the original aspect ratio.
%
100% keeps the original dimensions. Values below 100% make the image smaller. Values above 100% request an enlargement.
You requested an enlargement, but “Do not enlarge smaller images” is currently enabled. ByteTony will not silently upscale the image.

ByteTony scales each image to fit inside this box while preserving its aspect ratio. Images are not cropped to force the exact box shape.
Crop fills the exact output dimensions without stretching the image. Parts outside the selected crop area may be removed.

ByteTony scales the image proportionally until the requested area is filled, then removes only the excess edges according to your crop position.
This crop size is larger than the source image and would require upscaling. Disable “Do not enlarge smaller images” if you want to allow it.
Quick presets
Presets use “Fit within a box”. They preserve the original aspect ratio and do not crop the image.
ByteTony verifies browser support before creating a converted file so the file extension always matches the real output format.
Smaller file
Higher quality
Quality applies to JPG and WebP output. PNG uses a separate optimization process.
KB
ByteTony will try to get as close as possible to this size while respecting the resize and quality limits you selected.
ByteTony will never reduce the dimensions beyond your resize settings unless this option is enabled.
Your images are processed locally in your browser and are not uploaded to ByteTony. Resizing, cropping, or format conversion may remove metadata such as EXIF information.
Resized Images
ZIP is only used when downloading multiple resized images together. A single image is downloaded directly in its selected output format.
