Crop ratios and composition guides
This browser-based image cropper helps prepare profile photos, social media covers, phone wallpapers, and landscape images. Choose a ratio, position the subject, and use an optional composition guide.
Selection controls
Drag the selection to move it, or use any edge or corner to resize it. A fixed selection keeps its chosen aspect ratio while resizing.
Composition guides
Display one rule of thirds, diagonal, center cross, golden ratio grid, or golden spiral guide. The golden spiral has four orientations, and every guide follows the crop selection.
Formats and privacy
JPG, PNG, WebP, HEIC, and HEIF are supported. Decoding, preview, cropping, and export happen in your current browser, without uploading the image to a server.
Export and quality
Composition guides are preview aids and never appear in the exported image. PNG uses lossless encoding. JPG and WebP are re-encoded at maximum quality, so file size and metadata may change.
How to crop images
- Choose one image.
- Resize proportionally, or choose a crop ratio and move or resize the selection. You can overlay one composition guide.
- Export and download the image. Guides are not included.
Frequently asked questions
How do I crop an image to 3:4 or 4:3?
Choose Crop selection, then select 3:4 or 4:3. A centered selection appears automatically. Move it or resize it from an edge or corner, then export the image with the selected ratio.
How do I turn a landscape image into a 9:16 portrait image?
Choose the 9:16 ratio and move the crop selection over the subject you want to keep. Use the rule of thirds or center cross if helpful, then export the portrait image.
Are rule of thirds and golden spiral guides included in the export?
No. Rule of thirds, diagonals, center cross, golden ratio grid, and golden spiral are editing aids shown only in the preview.
Does cropping reduce image quality?
Cropping does not additionally resize the selected pixels, but browser export re-encodes the image. PNG uses lossless encoding. JPG and WebP may change slightly, and EXIF, GPS, HDR, or color profile data may not be preserved.
Is my original image uploaded while cropping?
No. Reading, cropping, composition preview, and export all happen in your browser. The original image is not sent to this site.
