Crop images by ratio or by exact pixels

Drag a box and it is cropped. Ratios and pixels both work. Local, nothing uploaded.

or start a blank document

Cropping looks like the simplest step and shapes the result more than any other: what you cut decides what someone sees first. And every platform wants its own proportions — square for avatars, wide for covers, 4:3 for print — so one picture usually has to become several.

Cropping simply takes a region out of the picture — no scaling is involved, so no quality is lost: the kept area is pixel-identical to the same area of the original. The download is a lossless PNG; if the original was a JPG the file may come out larger, but not a single pixel changes. A centred box covering 80% is there as soon as the image lands — drag its corners to resize, drag the middle to move it. The “Ratio” dropdown offers Free, 1:1, 4:3, 3:4, 16:9 and 9:16: 1:1 for avatars, 4:3 and 3:4 for everyday photos, 16:9 for covers, 9:16 for vertical. You can also type pixels into X, Y, W and H, say when you need precisely 800×600. Everything is computed in your own browser and the image is never uploaded.

Key features

One-click ratios

“Ratio” dropdown: 1:1, 4:3, 3:4, 16:9, 9:16 — pick one and the box locks to it; the default is Free.

Or exact pixels

Need precisely 800×600? Type the numbers instead of eyeballing it.

No quality loss

Cropping does not re-encode; what you keep matches the original pixel for pixel.

Runs locally

The image is never uploaded. Close the tab and nothing is left.

FAQ

Does cropping reduce quality?
No. Cropping just takes a region out — there is no scaling, so the kept area is pixel-identical to the same area of the original. The download is a lossless PNG: if the original was a JPG the file may be larger, but not a single pixel has changed.
Can I crop to an exact pixel size?
Yes — leave “Ratio” on “Free”, first set X and Y to 0 to fix the starting corner, then type 800×600 into W and H. The box never goes past the original: if the image is too small, the box simply stops at its edge with no separate warning — at that point what you want is resizing, not cropping.
Do I need an account? Is it paid?
Neither. Free, no sign-up, no usage cap, and no watermark.
Is my image uploaded?
No. Cropping runs entirely in your own browser — we never receive the file.
