Image Cropper
Crop images visually with aspect-ratio presets — output at full original resolution, never uploaded.
About this tool
Cropping is the most common photo edit there is — trimming distractions from the edges, cutting a rectangle to a square for a profile picture, reframing a screenshot to just the part that matters. And it's exactly the kind of light task where uploading your photo to some server, waiting, and downloading it back is absurd overhead. This cropper does the whole job in your browser.
Drag directly on the image to set the crop area, or lock an aspect ratio first: 1:1 for profile pictures and Instagram, 16:9 for thumbnails and covers, 9:16 for Stories and Reels, plus 4:3, 3:2 and free-form. The handles respect the lock, so the proportions can't drift while you adjust.
One technical detail separates this from many casual croppers: the crop is computed against the image's natural resolution, not the on-screen preview size. Crop a 4000×3000 photo displayed at 800px wide and the output pixels come from the full 4000px original — no silent quality loss. The dimensions readout under the preview shows the exact output size before you download, in the original format (JPG stays JPG, PNG stays PNG). Private by architecture: the photo never leaves your device.

Frequently asked questions
Does cropping reduce image quality?
Cropping itself only removes pixels outside the selection — the pixels you keep are untouched. This tool crops against the original file's full resolution (not the preview), so a crop from a 4000px photo retains its native sharpness. JPG re-encoding at 95% quality is the only, visually negligible, processing.
What crop sizes do social platforms want?
The presets cover them: 1:1 for profile photos and Instagram feed, 9:16 for Stories/Reels/Shorts, 16:9 for YouTube thumbnails and covers. Crop with the right preset and the platform won't re-crop your image unpredictably.
Is my photo uploaded anywhere?
No. The image is read directly by your browser and cropped with the built-in canvas API on your device. Nothing is transmitted — the tool works even offline once the page is loaded, which you can verify.
Why is my downloaded crop larger in pixels than the preview?
The preview is scaled to fit your screen, but the crop math runs on the image's natural resolution. The readout under the preview shows the true output dimensions — what you download is that size, not the shrunken preview.
