Crop Image Online
Crop images to custom dimensions or preset aspect ratios. Free, private, no upload needed.
Crop Images in Your Browser
Crop an image to a preset ratio — 1:1 for Instagram, 16:9 for YouTube thumbnails, 4:5 for Instagram feed posts — or drag a free-form selection for a custom crop. Cropping only removes pixels outside your selection; what's left is untouched, and nothing is uploaded to a server.
How to Use
- Drop or select an image
- Choose an aspect ratio preset, or leave on "Free" for custom
- Click and drag on the image to draw your crop selection
- Adjust quality if needed, then click "Crop"
- Download your cropped image
Common crop ratios
| Ratio | Common use | Typical pixel size |
|---|---|---|
| 1:1 | Instagram square, profile pictures | 1080×1080 |
| 4:5 | Instagram feed portrait | 1080×1350 |
| 16:9 | YouTube thumbnails, widescreen | 1920×1080 |
| 9:16 | Instagram/TikTok Stories | 1080×1920 |

After cropping, compress your image for smaller file size, or resize it to exact pixel dimensions.
Frequently asked questions
What aspect ratios are available?
Free-form plus common presets such as 1:1 (square), 16:9, 4:3, and 9:16, which are handy for social posts and thumbnails.
Does cropping reduce quality?
No — cropping just removes the area outside your selection; the remaining pixels are untouched.
What size is an Instagram square?
A 1:1 crop works well; Instagram displays square images at 1080×1080 pixels.
Is it private?
Yes — cropping is done locally in your browser.
What crop ratio is best for Instagram in 2026?
A 4:5 portrait crop (1080×1350) takes up more vertical space in the feed than a square and tends to get more engagement. 1:1 (1080×1080) remains the safe universal choice.
What crop ratio works for YouTube thumbnails?
Use 16:9, ideally at 1920×1080 pixels — YouTube requires a minimum of 1280×720.
Can I crop to an exact custom ratio?
Yes — leave the preset on “Free” to drag any region, or set exact pixel dimensions if you need a precise custom crop.
Does cropping change the image format?
No — the cropped image keeps its original format; only the pixel dimensions and framing change.
