Smart Crop: Resize Images to an Exact Size
Resize images to an exact size like 1280 × 640 or 1200 × 630 without cutting off titles or faces. ImgCompress finds the important part for you.
EditorGuideNew in v1.0
Social media previews, thumbnails and banners need an exact size. A plain resize either squashes the image or cuts it in the wrong place. Smart crop picks the best part for you and keeps titles, faces and other details in the picture.

Resize to an exact size#
- Drop your image into the upload area and click Edit.
- Open Size and pick a preset, e.g. GitHub preview (1280 × 640) or Link preview (1200 × 630). Or choose Custom and enter width and height.
- Under Fit to frame, choose:
- Fill frame: fills the whole frame, parts of the image are cut off. The crop box is placed for you.
- Blurred background: keeps the whole image; the free sides show a blurred, slightly darker copy.
- Solid color or Transparent: keeps the whole image on a color or on nothing.
- Check the preview. Move or resize the crop box if you like; Exact crop takes pixel values. Auto fit goes back to the automatic crop.
- Click Save, then convert.
For a batch, Auto fit all images prepares an automatic result for every file with the chosen size and mode. Open any file to check or adjust it before you convert.
From the command line#
bashdocker run --rm \ -v "$(pwd):/container/images" \ -v "$(pwd)/done:/container/done" \ karimz1/imgcompress:latest \ cli /container/images /container/done \ --format jpeg --fit 1280x640 --fit-mode crop
| Option | Values |
|---|---|
--fit WIDTHxHEIGHT | The exact output size, e.g. 1200x630. |
--fit-mode | crop (default), blur, solid, transparent |
--fit-anchor | auto (default, smart crop), center, top, bottom, left, right |
--fit-color | Fill color for solid, e.g. #ffffff |
All flags: CLI reference.
Advanced: how the crop is chosen#
It is fast and simple, and nothing leaves your container. ImgCompress tries every possible crop and keeps the one that shows the most detail and color. It avoids cutting through text or faces. If several crops are about as good, it picks the one in the middle, so a plain photo gets a plain centered crop. This takes much less than a second.
