Image Cropper
Drag an image here, or pick one to start. It never leaves your device.
Drag the box to move it, or drag a handle to resize. Pick an aspect ratio to lock the shape. Everything runs in your browser, so your image is never uploaded.
Crop any image to the exact region you need. Drop in a photo, drag the box or its handles to frame the shot, and snap to a preset aspect ratio like 1:1 or 16:9 when you want a fixed shape. The live overlay shows the pixel coordinates and aspect ratio as you adjust. Export to PNG or JPEG and see the file size before you download. Everything runs locally in your browser, so your image is never uploaded.
How to use
- Select or drop an image file. Most common formats including PNG, JPEG, WebP, and GIF are accepted.
- Drag inside the box to move the crop region, or drag any of the eight handles on the corners and edges to resize it.
- Pick an aspect ratio preset (Free, 1:1, 4:3, 16:9, 9:16, or 3:4) to lock the shape, or stay on Free to crop to any size.
- Watch the overlay for the live width, height, position, and aspect ratio in pixels as you adjust.
- Choose PNG or JPEG, click Crop image, then Download to save the result. The output file size is shown next to the preview.
Examples
- A 4000 by 3000 photo cropped to a centered 1:1 square gives a clean profile picture you can download as PNG.
- A wide landscape shot snapped to 16:9 and exported as JPEG at 90 quality produces a banner sized image with a small file.
- A 9:16 crop turns a horizontal photo into a vertical frame suited to phone wallpapers and stories.
FAQs
- Does my image get uploaded to a server?
- No. The crop runs entirely in your browser using the canvas element. The file is read locally and never sent anywhere, so private images stay private.
- What do the eight handles do?
- The four corner handles resize the width and height together from that corner. The four edge handles resize a single side. Dragging inside the box moves the whole region without changing its size.
- How do the aspect ratio presets work?
- Choosing a preset such as 1:1 or 16:9 locks the crop box to that shape, so resizing keeps the ratio fixed. Pick Free to crop to any width and height you like.
- Which output formats can I save?
- You can export PNG for a lossless result or JPEG for a smaller file. For JPEG a quality slider lets you trade detail for size. The final file size is shown before you download.
- Will cropping reduce the image quality?
- Cropping keeps the original pixels inside the selected region at full resolution, so PNG output has no quality loss. JPEG re encodes the result, and lower quality settings make smaller files with some detail loss.
- Is there a size limit?
- Files over roughly 25 MB or images larger than about 16000 pixels on a side may fail or be slow due to browser memory and canvas limits. Reduce the source first if you hit an error.
