Are my images uploaded to any servers?

No. Ucha operates 100% serverless and client-side. All crops, resizes, rotations, and filters are executed locally inside your browser's sandboxed memory. Your files never leave your computer.

What image formats are supported?

We support standard formats including JPEG, PNG, WEBP, and GIF. For RAW images or unsupported formats like HEIC, you can use our built-in Image Converter first to format them before editing.

Is there a limit on image size or dimensions?

No. There are no file size limits because all computations are handled by your own device. The maximum supported resolution depends solely on your computer's RAM and CPU capabilities.

Will resizing or cropping reduce the image quality?

Cropping simply extracts a region of pixels without reduction. When resizing, you can scale up or down. We provide a quality slider for JPEG and WEBP formats to control compression and keep details sharp.

How to Use the Free Online Image Editor

Ucha's Image Editor runs completely inside your browser using canvas. You do not need to install plugins or upload sensitive pictures to servers.

Load Image: Drag your PNG, JPG, WEBP, or GIF image onto the dropzone or click to browse.

Set Crop Box: Select preset ratios like 16:9 for YouTube thumbnails, 1:1 for profile pictures, or scale freeform.

Configure Dimensions: Input custom sizes. Aspect ratio lock ensures the image dimensions scale proportionally.

Apply Rotation & Filters: Tap buttons to rotate or mirror. Adjust brightness, contrast, and saturation using sliders.

Download Locally: Select output formats (PNG, JPG, or WEBP), adjust quality parameters, and download the edited file.

Frequently Asked Questions

Are my photos secure on Ucha?

Absolutely. Processing happens 100% locally inside your browser memory cache. We never transmit, upload, or store your photos on external servers.

Can I edit HEIC photos from iPhone?

Browsers cannot load HEIC formats directly. To edit iPhone photos, navigate to our Image Converter to format HEIC into PNG/JPG, then load it into this editor.

How does the crop function export work?

The editor fetches the coordinate values from the Cropper box, draws that slice onto a virtual canvas, scales the width and height, applies adjustments, and generates a download link.
