Crop Images Online
Crop JPG, PNG, and WebP images for free — select your crop area visually or enter exact dimensions. 100% client-side, your files never leave your device.
What Is an Image Cropper?
An image cropper removes unwanted outer areas from a photo or graphic, leaving only the region you select. Cropping is the most fundamental image editing operation — it changes composition, removes distractions, and adjusts aspect ratio without altering the pixels within the selected area. The cropped result retains the original quality because no recompression or resizing occurs on the kept region.
TweakFiles crops images entirely in your browser using the Canvas API. Your photo is never uploaded to any server, making it faster and more private than server-based tools. Traditional editors like Canva and Fotor upload your images to their servers for processing — meaning your personal photos pass through third-party infrastructure.
When to Crop Images
Cropping is essential whenever you need to adjust image composition or meet specific dimension requirements. Common scenarios include:
- Social media posts — crop to square (1:1) for Instagram, 16:9 for YouTube thumbnails, or 2:3 for Pinterest pins
- Profile photos — crop a headshot from a full-body or group photo
- E-commerce listings — crop product images to center the subject and remove background clutter
- Documents and forms — crop scanned documents to remove scanner margins
- Presentations — crop images to fit specific slide layouts without distortion
- Website banners — crop hero images to exact pixel dimensions required by your theme
How TweakFiles Crop Works
TweakFiles uses the browser’s native Canvas API and createImageBitmap to extract your selected region at full resolution. You select the crop area by clicking and dragging directly on the image preview, or by entering exact pixel coordinates. The cropped image is generated in the same format as your original (JPG, PNG, or WebP) with no quality loss in the cropped region. The entire process happens locally — no server, no upload, no waiting.
How to Crop an Image in 3 Steps
Upload Your Image

Select Crop Area
Click and drag on the image preview to draw a selection rectangle around the area you want to keep. The area outside your selection is dimmed. You can also enter exact pixel values for X, Y, Width, and Height below the preview for precise control.
