Is my image uploaded to a server?

No. Files are read locally with FileReader, decoded into a canvas, and re-exported via canvas.drawImage + toBlob. No network traffic is generated at any step.

Can I change the aspect ratio after starting?

Yes. Switching the aspect ratio updates the crop box immediately (position and zoom are preserved where possible). Drag again to fine-tune.

Which output format should I pick?

Use PNG for lossless output, JPEG for the smallest opaque files, or WebP for a transparent format that's smaller than PNG and JPEG. WebP works in all current major browsers.

Are EXIF / GPS metadata preserved?

No. The crop pipeline goes through canvas, which strips orientation tags, GPS data, and other EXIF fields. This is a useful side-effect when posting publicly.

Which image formats are supported?

Any format your browser can natively decode — JPEG, PNG, and WebP in practice. For HEIC photos from iPhone, convert them with the HEIC → JPEG tool first.

Is the output downscaled?

No. The crop box's position is mapped back to original pixel coordinates, so the output is pixel-accurate at full resolution. Zooming in the UI doesn't reduce output quality.

Image crop — drag to trim with free ratio or pixel size

Crop JPEG / PNG / WebP images by dragging directly on the preview. Pick an aspect ratio (free / 1:1 / 16:9 / 4:3 / 3:4 / 9:16) and an output format (PNG / JPEG / WebP) with quality control for the lossy formats. Your image never leaves the browser — every step runs locally.

How to use

Pick an aspect ratio (free / 1:1 / 16:9 / 4:3 / 3:4 / 9:16), then drop or choose an image. Drag on the preview to reposition; use the wheel or slider to zoom. Choose the output format (PNG / JPEG / WebP) and quality (for the lossy ones), then click Crop to download the result. The image is re-encoded through canvas so EXIF / GPS metadata is stripped. Nothing is uploaded — every step runs locally in your browser.
