Image Cropper

Cropping removes unwanted areas from an image to focus on the subject, change the aspect ratio, or meet specific platform dimension requirements. It's one of the most common image editing tasks, trimming a photo to a square for Instagram, removing a distracting background edge, cutting a wide panoramic into a 16:9 banner, or extracting a specific region from a screenshot. This tool gives you a visual drag-to-crop interface that runs entirely on your device with no upload required. Your cropped image saves to your device the moment you're done.

How to use

1. Open your image. Drop a JPG, PNG, or WebP file onto the tool or click to browse. The image loads in the crop interface immediately.
2. Choose an aspect ratio (optional). Select Free for a freeform crop, or pick a preset such as 1:1, 4:5, 3:2, 2:3, 16:9, or 9:16, and a crop box appears centered on the image automatically. Select Custom to enter any ratio, such as 5:7 or 7:5. On mobile, the preset box is ready to use immediately without drawing.
3. Draw or adjust the crop area. In Free mode, drag anywhere on the image to draw the crop box. With a ratio preset active, draw to set the box size while the ratio stays locked. The box is shown as a blue overlay. Once drawn, drag any corner or edge handle to resize it, or drag inside the box to reposition it.
4. Download the crop. Click Crop, then Save to download the selected region. The output matches the pixel dimensions of your selection at the original image resolution.

Adjusting the crop box

Once you have a crop box on the image, you can refine it without starting over. Drag any of the four corner handles to resize the box, and when a ratio preset is active, the opposite corner stays fixed and the ratio is maintained. Drag any of the four edge handles (top, bottom, left, right) to resize a single side, and in constrained mode the perpendicular dimension adjusts automatically to maintain the ratio, centered on the opposite axis. Drag anywhere inside the box to reposition it without changing its size. On desktop, the cursor changes to indicate which operation is available: crosshair outside, move inside, resize arrows on handles.

Tips for best results

• Use aspect ratio presets for social media. Instagram square posts use 1:1, portrait posts use 4:5, Stories and Reels use 9:16. All are direct preset buttons. For photography, 3:2 is standard DSLR landscape and 2:3 is portrait. Twitter/X headers (~3:1) and any other ratio not in the list can be entered using Custom. Tap a preset and the centered box appears immediately. No manual drawing required.
• Crop then compress. After cropping to the region you need, run the image through the image compressor to reduce file size. Compressing a cropped image is more efficient than compressing the full-size original.
• Crop then resize for exact output dimensions. The cropper outputs at the original image resolution for the selected area. If you need a specific pixel dimension (like exactly 1200×630 for Open Graph), crop first to get the right proportions, then resize to the exact pixel size needed.
• Check the crop preview before downloading. The preview shows you exactly what the downloaded file will look like. Take an extra moment to verify edges and composition before clicking Crop and Download.

Frequently asked questions

What is the difference between cropping and resizing?

Cropping removes parts of the image, it selects a region and discards everything outside it. Resizing scales the entire image up or down without removing any content. Cropping changes what's visible; resizing changes the overall scale. For changing platform dimensions, you often need to do both: crop to the correct ratio, then resize to the exact pixel dimensions with the image resizer.

What aspect ratio should I use for Instagram?

Instagram supports three aspect ratios: square posts at 1:1 (1080×1080 px), portrait posts at 4:5 (1080×1350 px), and landscape posts at 1.91:1 (1080×566 px). For Instagram Stories and Reels, use 9:16 (1080×1920 px). The 1:1, 4:5, and 9:16 presets are all available as direct preset buttons. Click one and the crop box appears centered, then click Crop and Save.

Does cropping reduce image quality?

Cropping itself does not reduce quality, it simply removes pixels outside the selected region. The remaining pixels are unchanged. Quality reduction occurs when the output is then resized up (adding pixels the original doesn't have) or when a lossy format like JPG applies a second round of compression. Cropping and saving to PNG preserves perfect quality for the cropped region.

Can I crop to an exact pixel dimension?

The cropper outputs the selected region at the original image resolution. To get an exact output size in pixels, crop to the correct aspect ratio first, then use the image resizer to scale the cropped result to your exact target dimensions. This two-step process gives precise control over both composition and output size.

What formats are supported?

JPG, PNG, and WebP are accepted as input. The output format matches the input, a PNG crop produces a PNG output, preserving any transparency. If you need to change the format after cropping, use the image converter on the cropped result.

Can I crop multiple images at once?

The cropper is designed for one image at a time since each crop requires an individual visual selection. For batch-cropping multiple images to the same dimensions, the most efficient approach is to process them one at a time here, or to use image editing software like Photoshop's batch processing or ImageMagick for automated bulk operations.
