Image Cropper

Keep the part of a photo that matters. Toolinet’s free image cropper lets you adjust the frame, remove unwanted edges and prepare a different image shape. Work with a live crop preview, choose an aspect ratio or enter pixel coordinates. Rotate, flip and review the composition before creating your download.

What an image cropper changes

Cropping removes pixels outside a selected rectangle or shape. It is useful when a photo includes too much empty space, a subject is off-center or a design needs a square rather than a landscape frame. It does not shrink the whole scene into a smaller canvas in the way proportional resizing does.

The tool accepts JPG, PNG and WebP, with up to 20 images and a maximum of 30 MB per image. Your selected files are processed in the browser. Keep a separate original if you may need another crop later.

How to crop an image online

1. Add an image. Choose images, drop supported files into the tool or try the built-in sample.
2. Pick an aspect ratio. Use Freeform for flexible framing or lock a ratio such as 1:1, 4:5 or 16:9.
3. Adjust the crop area. Move the box and drag its handles. You can draw a new crop or enter pixel selection values.
4. Refine the composition. Use the grid, center controls, rotate or flip when needed.
5. Check Crop preview. Confirm the subject, edges and output dimensions before processing.
6. Create the output. Run Crop & download, then save the completed image or use the ZIP option for completed files.

Freeform, fixed ratios and custom shapes

Freeform lets width and height change independently. A fixed aspect ratio keeps the selected shape while you resize the crop. A 1:1 ratio creates a square, 4:5 creates a portrait frame and 16:9 creates a wide frame. A ratio describes shape, not a guaranteed pixel count.

For example, 1000 × 1000 and 600 × 600 are both 1:1. If the destination needs a specific output size, choose the composition here and use the Image Resizer afterward. This keeps framing and final dimensions as separate decisions.

Use pixel coordinates for a precise crop

Position X and Position Y describe where the selection begins. Width and Height describe the selected area in pixels. Coordinates follow the rotated image, and the crop remains inside the source boundaries. Whole-pixel rounding can slightly change a selection when a ratio is locked.

The crop area also supports keyboard adjustments described beside the editor. The rule-of-thirds grid can help place a face, product or horizon, but it is only a guide. Moving the frame to protect important details is more useful than following a grid mechanically.

A square-crop example

During Toolinet site testing on 25 October 2026, the built-in 1600 × 1000 landscape sample was cropped to a 1000 × 1000 JPG. The exported file was checked at those dimensions. A centered square of that size keeps the source height and removes 600 pixels from the total width.

Your crop does not have to be centered. Move the frame toward your subject, keep text and logos inside the selection and leave breathing room around faces. Review all edges before downloading.

Rectangle or circle: choose the output carefully

A circular crop needs a rectangular image file to store it. If you want the corners outside the circle to be transparent, use an output format that supports transparency, such as PNG. JPG cannot preserve transparent pixels and needs a solid background.

Some websites apply their own circular mask to a square profile photo. In that case, a well-framed square can be more useful than exporting a circle yourself. Check how the receiving application displays the image.

Rotate, flip, zoom and undo

Rotate and flip controls change orientation or mirror the image. Zoom changes your editor view rather than the exported pixel dimensions. Use Fit view to see the working area, then check the reported crop size for the actual output.

Undo and redo help compare framing changes. Reset this image restores the working selection for that image. The original file on your device stays unchanged; the downloaded crop is a new file.

Crop first, then resize and compress

For a product listing or article image, crop to the right composition, resize to the required dimensions and finish with the Image Compressor if you need fewer bytes. Use the Background Remover when you need to separate a subject from its background rather than remove outer edges.

Limitations and privacy

Cropping cannot reveal parts of a scene that were never captured, restore hidden objects or sharpen a low-resolution source. A tight crop also leaves fewer pixels for a large print. Start from the original image rather than repeatedly editing compressed copies.

Cropped downloads remove EXIF metadata. Processing happens locally, while ordinary page and asset requests still reach the website host. Read the privacy information and browser help for more context. If a large batch fails, try one smaller supported image.
