Contain retains every image edge. Cover takes a centred crop before scaling so the output fills the shape naturally.
Open the downloaded file and check dimensions, crop, colors, transparency, size, and the destination's requirements.

No. The selected image, preview, and downloaded output remain in the active browser. Rigid Apps does not receive the source file.
Yes. Enter centimetres and a PPI value. The tool calculates pixels as centimetres divided by 2.54, multiplied by PPI.
Pixels per inch describes print density. It converts a physical width or height to a pixel target; it does not guarantee printer quality.
Contain preserves every part of the image and its proportions. It may leave unused space around the resized image.
Cover uses a centred crop to fill the requested shape. It preserves proportions but removes edge content when needed.
No. Cover mode crops first, then scales. The separate stretch option is only available in the resize tool and asks for confirmation.
The last unit, dimensions, PPI, fit mode, format, and quality are stored in this browser only. Image files are not saved.
JPG, PNG, and WebP. JPG does not preserve transparency; PNG is lossless; WebP support depends on the browser.
A smaller pixel target or lower JPEG/WebP quality often reduces size, but the result depends on the source image and format. Use Image Compressor to compare actual bytes.
Use the Batch Image Resizer for up to 20 local images and a ZIP download.
Cropping, format conversion, transparency, quality, and browser encoding can affect appearance. Inspect the downloaded output before replacing an original.
Check the destination's current image dimensions, aspect ratio, format, and file-size requirements. This tool creates your requested output but cannot validate every platform.
