How to crop a photo
- 1. Add an image.

- 3. Click download — the crop is taken from the full-resolution original.
Want a round avatar instead of a rectangle? Use the circle crop tool. Need to change the overall size afterwards? Try the image resizer.
Frequently asked questions
Can I crop to a square for Instagram?
Yes — click the 1:1 preset for a centered square, then drag to position it, and download.
Is the crop done at full resolution?
Yes. The on-screen box is just a guide; the download is cropped from the original full-resolution image.
Are my images uploaded?
No. Cropping runs in your browser; the image never leaves your device.
How this tool helps
An image often contains extra background or needs a specific framing for a post, card, or thumbnail. Use the ratio presets when the destination requires 1:1, 4:3, or 16:9; use free crop for a custom frame.
How to use it
- Add an image.
- Drag the crop box and choose a ratio when needed.
- Review the framing and download the crop.
Example
Crop a landscape photo to 16:9 for a video thumbnail without changing the original file.
What you get
The output contains only the selected region and is downloaded as a new image.
Good to know
Limitations: Cropping removes pixels outside the box. Start with the largest source image available for the best result.
Privacy: Cropping is performed on-device in the browser.
How PixelTools makes this decision
PixelTools shows the settings and the result side by side so you can make an informed choice before downloading. File size is measured from the actual browser-generated output, while dimensions, format, and visual preview are kept visible because a smaller file is not automatically a better file. The original is never overwritten.
These tools are maintained as practical, browser-first utilities rather than upload forms. We document the trade-offs for each task, test the output in the browser, and link to related guides when a different format or workflow may be a better fit. For troubleshooting, see Help & Support; for the full data-handling explanation, read the Privacy Policy.
