TidyToolsCropping and resizing are not the same job
They get confused constantly, and the difference matters. Resizing scales the whole picture — everything stays in frame and the pixels get smaller. Cropping cuts pixels away at the edges — what remains is at its original size, and the rest is gone.
So if a photo is the wrong shape, cropping is the answer. If it's the wrong size, resizing is. Most "my profile picture looks wrong" problems are shape problems: the image is fine, the platform just needed a square and took one from wherever it felt like.
A worked example
You have twenty product shots at 4032 × 3024 from a phone, and the marketplace shows square thumbnails. Uploaded as they are, each one gets its sides chopped off automatically, and on a few of them that removes the part of the product you were trying to show.
Drop all twenty in, choose 1 : 1, and leave the anchor in the centre. Each becomes a 3024 × 3024 square — full resolution, no scaling — and you can see in the list what survived before uploading anything. Where the centre was wrong, switch the anchor and the previews update immediately.
Choosing where the crop happens
The nine-square control decides which part of the picture is kept when the shape has to change. Centre is the sensible default and what every automatic cropper does, but it's frequently the wrong choice:
- Top centre for portraits going into a square or tall frame. People stand in the middle of a photo but their faces sit in the upper third, and a centre crop cuts foreheads off.
- Bottom for landscapes where the sky is doing nothing and the interest is on the ground.
- Left or right when your subject is off to one side — which, if you framed it well, is often exactly where it is.
The two thumbnails on each row show the original and the result, so you can check rather than guess.
The ratios worth knowing
4 : 5 is the most useful and least known. It is the tallest shape Instagram will show in the feed, so it occupies the most screen space on a phone; anything taller gets cropped by the platform anyway. 9 : 16 is full-screen vertical for stories and reels. 1.91 : 1 is the shape used for link previews on most social platforms, which is why a shared article image so often looks awkwardly letterboxed — it was made square.
3 : 2 is what most cameras shoot and what 6 × 4 prints expect. 4 : 3 is what phones and older screens use. If you're printing, match the print size: a 5 × 7 needs 7 : 5, and cropping it yourself beats letting the lab decide.
Cropping is not redaction
Worth stating plainly because the mistake is common and consequential. When you crop here, the discarded pixels are not written into the file you download — they are genuinely absent from it, and nothing can recover them.
That is not true of cropping in many editors and document formats, where a crop is stored as an instruction to display part of the image while the whole thing stays embedded. Anyone can undo it. If your reason for cropping is that something must not be seen, don't rely on a crop you performed elsewhere — and if you need to obscure something in the middle of a picture rather than at its edge, use the screenshot redactor, which destroys the pixels outright.
Frequently asked questions
Are my images uploaded anywhere?
No. Cropping happens in your browser and the files never leave your device. There is no server, no account and nothing stored. Load the page once, go offline, and it still works.
Does cropping reduce the quality?
No pixels are scaled, so what remains is exactly as sharp as it was. The picture is smaller only because it contains less of the scene, not because anything was degraded.
What size will the cropped image be?
As large as the ratio allows within the original. A 4032 × 3024 photo cropped square gives 3024 × 3024. Each row shows the exact result before you download.
Can I crop a batch to the same shape?
Yes. The ratio and anchor apply to every image dropped in, and portrait and landscape photos are each handled correctly. Take the results individually or as a single ZIP.
How do I stop a platform cropping my photo badly?
Crop it to the platform's shape yourself before uploading. Once the image already matches, there is nothing left for the automatic cropper to remove.
Can I get an exact pixel size as well?
Crop to the shape here, then run the result through the resizer for an exact width and height. Doing it in that order means the resize never has to crop anything itself.
Are the cropped-off parts really gone?
Yes — the downloaded file contains only the pixels you kept. Note this is not true of crops applied inside many editors and documents, where the full image often stays embedded and the crop can be undone.
