Image Cropper
Crop images with social platform aspect presets — Instagram, TikTok, YouTube, and more, all in-browser.
Images never leave your browser.
About this tool
Wrong aspect ratios force platforms to auto-crop your images — often cutting faces or text awkwardly.
Crop locally with platform presets before uploading so you control the frame.
How to use the Image Cropper
- 1
Upload your image (processed locally — never sent to a server).
- 2
Select a platform preset or custom aspect ratio.
- 3
Crop, preview, and download the result instantly.
Preset selection
Instagram feed: 1:1 or 4:5. Stories/Reels: 9:16. YouTube thumbnail: 16:9.
Design within the target ratio from the start — cropping after loses composition.
Pro tips
- Leave safe margins for Stories UI overlays at top and bottom.
- Use image dimension checker to verify export size before posting.

Frequently Asked Questions
Are images uploaded to your servers?▼
