About this tool

Cropping selects the right framing for a product photo, centers a portrait for a profile picture, or removes distracting elements from a screenshot - all without opening a full editor. Pick a ratio for the destination (1:1 for profile pictures, 4:5 or 9:16 for social posts and stories, 16:9 for video thumbnails, 3:2 or 4:3 for photo prints), or leave the selection free.

Changing the ratio keeps your selection's centre instead of throwing it away. Optionally type a width or height in pixels (with a lock to keep the shape) to get an exact size, and choose JPEG, PNG or WebP with a quality setting for JPEG and WebP.

The result shows its size in pixels, its file size and its format before you download it, and the file is named after your original, for example photo-cropped.jpg.

This image cropper lets you drag a selection over your picture, lock it to a ratio (1:1, 4:3, 3:2, 16:9, 5:4, 2:3, 4:5, 9:16 or your own custom ratio), type an exact output size in pixels, and save the result in its own format. A JPG stays a JPG, a PNG stays a PNG with its transparency, and a WebP stays a WebP. Photos taken on a phone are shown upright, so you crop what you actually see.

How to Use Image Cropper

Upload Image

Upload or drop a JPG, PNG, WebP, AVIF, GIF or BMP image you want to crop.

Adjust Crop Area

Drag and resize the crop box, or choose a ratio such as 1:1, 4:3, 16:9 or a custom one. Optionally type an exact output size.

Preview Result

Click Crop Image to see the result with its size, format and file size before you download it.

Download Image

Download the cropped image, saved in its original format unless you chose JPEG, PNG or WebP.

Common Workflows

Square Crop for Profiles

Choose 1:1 for a profile picture or square social media post.

Social and Story Formats

Use 4:5 for feed posts or 9:16 for stories and reels, then set the width you need.

Widescreen or Video Crop

Use 16:9 for a video thumbnail or widescreen banner.

Your Own Ratio

Choose Custom and type the two numbers, for example 21 and 9.

Exact Pixel Size

Type a width or height in the Output size box. With the lock on, the other side follows the shape of your crop.

Best For

  • Crop freely by dragging, or lock the shape to 1:1, 4:3, 16:9, 3:2, 5:4, 2:3, 4:5, 9:16 or a custom ratio you type. Changing ratio keeps the centre of your selection.
  • Output keeps your picture's format: JPEG stays JPEG, PNG stays PNG with its transparency intact, WebP stays WebP (in browsers that can create WebP). You can also choose JPEG, PNG or WebP yourself, and JPEG and WebP have a quality setting from 10 to 100.
  • Type an exact output width or height in pixels, with an aspect-ratio lock. Enlarging is off by default, and you can allow it if you need a bigger result.

Examples

Crop a photo to a square and an exact size

Source & Settings

holiday.jpg - 4000x3000, ratio 1:1, output width 1080

Result

holiday-cropped.jpg - a 1080 × 1080 JPEG, the same format as the original

The crop is cut from your original pixels, then scaled down to the width you typed. A transparent PNG cropped the same way would come out as a PNG with its transparency kept.

Use Cases

Cropping a photo to a square profile picture

Choose 1:1 and move the box over the face or subject, then type the width the platform asks for.

Cropping to a video thumbnail ratio

Use 16:9 to select a widescreen region matching common video thumbnail dimensions.

Cropping a logo or cut-out and keeping its transparency

Upload a PNG or WebP and keep the format on Original: transparent areas stay transparent in the result.

Common Mistakes

Problem

Choosing JPEG for a transparent picture

Solution

JPEG has no transparency. If you choose JPEG for a PNG or WebP with transparent areas, they become white (the tool tells you so). Keep the format on Original or choose PNG to keep transparency.

Problem

Typing a size bigger than the cropped area

Solution

Enlarging is off by default, so a size larger than your selection is refused with an explanation. Turn on Allow enlarging if you really want a bigger result, knowing it can look soft.

Problem

Expecting the box to be redrawn by clicking on the picture

Solution

The selection is moved and resized with its edges and corners (or the arrow keys when it is focused). Picking a ratio or Free reshapes it around its current centre.

Problem

Looking for a circle crop or rotation option

Solution

Neither exists in this tool - only rectangular crops are available. Phone photos are shown upright automatically, but there is no rotate or flip control.

Tips & Best Practices

Pick the ratio that matches your destination

1:1 for square profile pictures, 4:5 for feed posts, 9:16 for stories, 16:9 for widescreen or video thumbnails, 3:2 or 4:3 for photos - or Free for anything else.

Set the ratio first, then move the box

Changing the ratio keeps the centre of your selection, so you can switch shapes without starting over, but choosing the shape first is quicker.

Use PNG or Original to keep transparency

WebP also keeps transparency. JPEG always flattens it to white.

Check the result panel before downloading

It shows the final pixel size, format and file size. The crop is cleared whenever you change the selection or a setting, so what you see always matches the current choices.

Limitations

Rectangular crops only, no rotate or flip

There is no circle or other shape, and no rotate, flip or zoom control. Phone photos are turned upright automatically.

WebP output depends on your browser

WebP is offered only in browsers that can create WebP files. If one can't, a WebP picture is saved as PNG instead and the tool says so. AVIF, GIF and BMP pictures are saved as PNG (a GIF is cropped from its first frame).

Metadata is not kept

EXIF data such as GPS location and camera details is not carried into the cropped file.

Very large images are refused

A picture of more than about 150 megapixels, or a result larger than 16,384 pixels on a side or 100 megapixels, is refused with a message instead of risking a browser crash.

One image at a time

Drop or choose a single picture. Use Upload another image to switch to a different one.

Comparisons

Image Cropper vs Image Resizer

Cropping cuts away part of the image at its original scale; resizing changes the whole image's dimensions.

Image Cropper (this tool)Image Resizer
What changesWhat's kept - cuts away part of the imagePixel dimensions - the whole image scales up or down
Exact pixel controlYes - crop first, then type an optional output width or heightYes - type an exact width and height, or a percentage
Best forRemoving unwanted parts or matching a shape or ratioScaling a whole image to a required pixel size

Which should you use?

Use the Cropper to cut away part of an image or match a ratio, optionally at an exact size. Use the Image Resizer when you want to scale the whole picture without cutting anything.

FAQs

The most common questions are what format the cropped image comes out in and whether transparency survives. Your original format is kept, and transparency is kept for PNG and WebP. The FAQ below covers that along with exact sizes, ratios and phone photos.

What is the difference between cropping and resizing an image?

Cropping cuts away the parts of the picture outside the box you draw, so you keep only part of it. Resizing keeps the whole picture and changes its width and height in pixels. This cropper can also scale the area you keep to an exact size, but to shrink or enlarge a whole image without cutting anything off, use the Image Resizer.

Can I crop to an exact pixel size, like 600x600?

Yes. Choose 1:1 for the shape, then type 600 in the Width box under Output size; with the aspect lock on, the height becomes 600 too. The crop is cut from your original pixels and scaled to that size. Enlarging beyond the cropped area is off by default, and you can allow it.

Does cropping keep my PNG's transparent background?

Yes. With the format on Original, a PNG stays a PNG and transparent areas stay transparent, and a WebP stays a WebP with its transparency. Only if you choose JPEG do transparent areas become white, and the tool tells you so before you crop.

What format is the cropped image saved in?

The same as your original by default: JPEG stays JPEG, PNG stays PNG and WebP stays WebP (where your browser can create WebP, otherwise it is saved as PNG and the tool says so). You can also choose JPEG, PNG or WebP yourself. AVIF, GIF and BMP pictures are saved as PNG.

Which aspect ratios are available?

Free, 1:1, 4:3, 16:9, 3:2, 5:4, 2:3, 4:5, 9:16 and Custom, where you type any two positive numbers (up to 20:1). Switching ratio keeps your selection's centre and roughly its size.

Will a phone photo be cropped the right way up?

Yes. Photos with a rotation tag are shown upright, so the area you select is the area you get, with no need to rotate the file first.

Can I crop an image into a circle or rotate it?

No, only rectangular crops are available, and there is no rotate or flip control. Phone photos are turned upright automatically.

What is the downloaded file named?

After your original name, for example photo.png becomes photo-cropped.png with a brand suffix. The extension always matches the real format of the file.

Is the cropping done on my device?

Yes. CoditTools crops the image entirely in your browser using JavaScript. Your file is never uploaded to any server.
