📖How to Use the Image Cropper

  1. 1
    Upload your image

    Drag and drop an image or click to browse. The image loads into the interactive crop canvas where you can drag a selection rectangle, drag its corners to resize, or drag it to reposition. The selection shows live dimensions in pixels.

  2. 2
    Set crop dimensions or aspect ratio

    Drag the crop handles freely, or lock to an aspect ratio (1:1 for square, 4:3, 16:9, A4 portrait, A4 landscape). For pixel-precise crops, type exact Width and Height values directly. The crop overlay highlights the selected area and grays out what will be removed.

  3. 3
    Crop and download

    Click Crop to apply. For bulk mode, set the crop settings once — aspect ratio and position relative to the image — and they are applied to all uploaded images. Download as JPG, PNG, or WebP, or ZIP in bulk.

Frequently Asked Questions

What is aspect ratio lock and when should I use it?

Aspect ratio lock constrains the crop selection so its width-to-height proportion stays fixed as you resize. Use 1:1 for Instagram profile pictures and square posts, 4:3 for standard photo prints and presentations, 16:9 for YouTube thumbnails and widescreen displays, 3:2 for standard DSLR photo proportions and 6×4 inch prints, and 9:16 for Instagram Stories and TikTok verticals. Custom lets you enter any ratio like 5:4 or 7:3.

Can I enter exact pixel dimensions for the crop?

Yes — switch to Pixel mode and type the exact width and height in pixels. The crop box snaps to those dimensions. If you type a dimension larger than the image, the crop box is limited to the maximum available. This mode is ideal when images need to meet exact size requirements for social media platforms, print shops, or CMS uploads.

Does cropping reduce image quality?

No — cropping removes pixels from the edges; it does not scale or compress the remaining area. The cropped portion retains full original quality. A slight quality reduction may occur if you download as JPEG (standard compression), which is avoided by choosing PNG or WebP output.

How does bulk crop mode work?

In bulk mode, you set a crop preset (aspect ratio plus position: centre, top-left, top-right, bottom-centre, etc.) which is then applied to every uploaded image. This applies a consistent crop to all images — for example, cropping every photo to a centred 1:1 square for a social media grid. Individual preview and adjustment is available before downloading the ZIP.

What is the minimum/maximum crop size?

The minimum crop is 10×10 pixels to prevent accidentally creating a single-pixel output. There is no maximum — you can crop the full image (which returns the original). The crop coordinates are stored as pixel values and applied to the original full-resolution image, not to the scaled preview.

Can I undo a crop?

The Reset button restores the crop selection to full image size, effectively undoing any crop before you apply it. Once you click Crop and download, the crop is permanent in the downloaded file. The original upload is not modified, so you can re-crop by adjusting the selection and clicking Crop again.
