What it does

Drag to crop any region, with fixed ratios for avatars, video and social posts.
How to use it
Here is the short version of using Crop Image.
- Open the image — The crop box starts near the full frame.
- Drag the selection — Choose a fixed ratio or keep it free, then drag over the area to keep.
- Crop and download — The PNG output contains only the selected pixels at their original resolution.
Features that matter
What Crop Image does well.
- Nothing leaves your device — The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
- No upload wait — You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
- Free, no account, no quotas — No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.
Frequently asked questions
Is my image safe to use here?
Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.
Do I need to create an account?
No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.
Does it work on a phone?
Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.
Does cropping reduce quality?
No. Cropping copies existing pixels without resampling. The output is smaller in dimensions but identical in quality inside the crop.
What ratios should I use for social media?
1:1 for avatars and feed posts, 16:9 for YouTube and slides, 9:16 for stories and Reels, and 4:5 for Instagram portraits.
