Is my image uploaded while I trim it?

Trimming runs in this tab: the Canvas API copies only the pixels inside your box to a new canvas and encodes the download from it. Our servers are not involved at any point.

What is the difference between trimming and cropping an image?

They describe the same action: removing the outer parts of an image to keep a chosen region. This trimmer keeps the pixels inside the box you draw and discards the rest.

Which image formats can I trim?

JPEG, PNG, WebP, GIF, and most other common formats can be loaded. The trimmed image downloads as JPEG or PNG.

Does trimming reduce image quality?

Trimming keeps the pixels inside the box. Download as PNG to keep them exactly as they were; a JPEG download is re-encoded at quality 0.92, which adds a little compression for a smaller file.

Image trimmer

Trim away the parts of an image you do not need. Drag a box around the area you want to keep, lock an aspect ratio if you need one, and download the trimmed result. All processing runs in your browser.

How it works

The tool reads your image into browser memory and displays it in an interactive crop preview. Drag the crop box to reposition it, or pull the corner handles to resize. When you click Crop & download, the Canvas API draws the selected region to an offscreen canvas in your browser tab and exports it as a file.

Processing runs in your browser

The Canvas API processes the crop operation locally, and the resulting file is downloaded directly to your device. Our servers are not involved at any point.

After cropping, scale the result with resize image. To switch the saved format, use the image converter. For turning a sideways photo upright before cropping, see image rotate.
