What does this image cropper do?
This tool cuts a rectangular region out of one or more images, either as a freeform selection or locked to a specific aspect ratio like 1:1 or 16:9. It runs entirely in your browser using the Canvas API, so nothing is uploaded to a server - your images never leave your device.
How to crop an image
- Drop one or more images onto the drop zone, or click Browse files.
- Pick a ratio - Freeform for any shape, a common preset like 16:9 or 9:16, or a social media preset sized for a specific platform.
- Drag the crop box to reposition it, or drag a corner handle to resize it. Rotate the active image left or right if it needs straightening or reorienting first.
- Toggle the rule-of-thirds grid or safe-area guide to help position the subject.
- Click Crop this image for the active file, or Crop all images to apply the current ratio to the whole batch at once.
- Download a single result or grab everything as a ZIP.
Freeform, preset, and social media ratios
Freeform mode lets you drag the crop box to any shape with no constraint. Preset ratios like 1:1, 4:3, 3:2, 16:9, 9:16, 3:4, 2:3, and 21:9 lock the box to that exact proportion as you resize it. The social media presets go a step further and match the dimensions specific platforms expect - an Instagram Story crop stays at 9:16, a LinkedIn banner stays at 4:1, and so on - so you don't have to look up the correct ratio yourself.
Rotation
Use Rotate left or Rotate right to turn the active image in 90-degree steps before cropping - useful for images captured sideways or upside down, or when you want a portrait crop from a landscape photo. Rotation is applied per image, so a batch can mix images that need rotating with ones that don't.
Safe-area and rule-of-thirds guides
The rule-of-thirds grid overlays two evenly spaced horizontal and vertical lines across the crop box, a classic composition aid for placing your subject off-center. The safe-area guide outlines the inner region of the crop that stays clear of the edges - useful when a platform like Instagram or TikTok overlays profile icons, captions, or buttons near the border of a Story or Reel.
Batch cropping
Drop in multiple images and each one keeps its own crop box, rotation, and position - editing one image doesn't disturb the others. Pick a ratio, adjust the active image's box, then click Crop all images to apply that same ratio (centered on each image) across every file that hasn't been cropped individually yet, and download the whole set as a ZIP.
Common uses
Social media posts
Crop a photo to the exact ratio a platform expects before uploading, so it isn't re-cropped or repositioned unpredictably by the platform itself.
Portraits and thumbnails
Tighten a crop to a square or portrait ratio for a profile picture, product thumbnail, or avatar.
Straightening and reframing
Rotate a sideways photo, then crop out unwanted background or empty space to focus on the subject.
Frequently asked questions
Does cropping reduce image quality?
No. Cropping keeps the original pixel resolution of the selected region - you're only removing what's outside the selection, not resampling what remains.
Can I crop multiple images at once?
Yes. Drop in as many images as you like, pick an aspect ratio, fine-tune the crop box on each image if needed, then click Crop all images to process the whole batch and download everything as a ZIP.
What are safe-area guides for?
Safe-area guides show the inner region of a crop that stays clear of platform overlays, like profile icons and captions on Stories and Reels, plus a rule-of-thirds grid for balanced composition.
Are my images uploaded anywhere?
No. Loading, cropping, rotating, and exporting all happen locally in your browser using the Canvas API. Nothing is sent to a server.
What file format does the export use?
Cropped images download as PNG, which preserves transparency if the original had any.
