Crop an Image

Take a slice off each edge of a picture. Useful for tightening a scan, removing a dark border, or clearing something out of the frame.

How to use it

Add the picture

Drop the image above or click to browse. Several can be added at once, and the same crop is applied to each.

Set the trims

Enter a percentage for each edge you want to take off. 10 on the left removes a tenth of the width from that side.

Keep the total sensible

The tool refuses a crop that would remove almost the whole picture, so you cannot lose a photo by accident.

Choose the output

JPEG suits photos, PNG keeps sharp edges, WebP is smaller but not accepted everywhere.

Download

Each cropped picture is saved with "-cropped" added to its name, so the original stays easy to identify.

Common issues

The result is nearly empty

The four trims added up to almost the whole picture. The most extreme case is blocked, but a crop that leaves only a thin strip is still possible — lower the numbers if that was not the intent.

A stray hand or shadow is still there

Trimming from an edge only removes a straight margin. Removing something inside the frame needs retouching, which this tool does not do.

A white band appeared on one side

That usually means the original had a border and the crop stopped partway across it. Increase the trim on that side until the border is gone.

A batch came out framed differently for each photo

Percentages apply per picture, so a wide shot and a tall shot lose different amounts of content. Crop mixed batches one at a time for consistent framing.

Frequently asked questions

How do the percentages work?
Each one is a share of that dimension. Trimming 20% from the left and 20% from the right keeps 60% of the width; the same applies vertically.
Why not drag a box on the picture?
Amounts are entered as numbers, which keeps a whole batch identical and works on a phone where dragging a small handle accurately is awkward.
The picture is still off-centre
Trimming by numbers cannot see the subject. If the content sits to one side, trim more from that side — try a few values and check the result.
Can I crop to an exact ratio, like a square?
Not directly. Work from the picture’s pixel size: to make a 1200×800 photo square, remove 400 pixels of width — about 17% from one side, or 8% from each.
Does cropping reduce the file size?
A little, in proportion to the pixels removed. Re-encoding can offset the gain, so keep the quality setting high unless size matters more.
Will the crop keep the image sharp?
Yes. Cropping only discards pixels; everything that remains is untouched, so nothing is softened.
Can I undo a crop?
Not in the saved file. The original on your computer is never modified, so keep it and crop again if the result is not right.
Is transparency preserved?
With PNG and WebP, yes. A JPEG crop fills transparent areas with white.
Is anything uploaded?
No. The picture is cropped and re-saved in your browser.
