Is my image uploaded to a server?
No. This tool processes your image entirely inside your browser using the Canvas API. Your image never leaves your device — it is 100% private and works offline once the page is loaded.
What image formats are supported?
You can open JPG, PNG, WebP, GIF and BMP images. For output, choose between JPG (smaller file, lossy), PNG (lossless, supports transparency), or WebP (best compression with high quality).
Can I crop to an exact pixel size?
Yes. After dragging to select, you can manually type exact X, Y, Width and Height values in the crop fields. You can also use aspect ratio presets (1:1, 16:9, 4:3 etc.) to constrain the selection proportionally.
What is the maximum image size?
Up to 20MB. Very large images (over 6000×6000 pixels) may be automatically scaled down in the preview to fit your screen, but the output will always be at the full requested resolution.
