How to use it
- Add your images.

- Keep the aspect ratio or set exact dimensions; presets crop to fill the size.
- Download individual images or a ZIP.
Sizes for social media
Presets include Instagram square (1080×1080) and portrait (1080×1350), stories and reels (1080×1920), Facebook and Open Graph link images (1200×630), YouTube thumbnails (1280×720), X posts (1600×900) and LinkedIn banners (1584×396).
Sharp results
Large reductions are done in several steps with high-quality smoothing, which avoids the jagged look of one-step scaling. Use “Do not enlarge” to keep small images from becoming blurry.
Frequently asked questions

Are my photos uploaded anywhere?
No. The image is decoded and processed by JavaScript and WebAssembly inside your browser tab. Nothing is sent to our server, and the result is generated on your device. You can even disconnect from the internet once the page (and, for AI tools, the model) has loaded.
Can I resize without cropping?
Yes. With “Pixels” and “Keep aspect ratio”, the image fits inside the width and height you enter without any cropping.
What does a preset do with a different shape?
Presets fill the exact size and crop the edges evenly from the centre. Use the crop tool first if you want to choose what stays in the frame.
