How to crop an image

1

Upload your image

JPEG, PNG, WebP or AVIF. Nothing is uploaded, it stays on your device.

2

Pick a ratio or preset

Standard ratio, social preset, or free-form for any shape.

3

Rotate, flip or straighten

90-degree buttons for orientation, the slider for a tilted horizon.

4

Drag the crop box

Resize by handle, or type exact pixel dimensions in the sidebar.

5

Download

JPEG, PNG or WebP. The crop applies directly, no preview step required.

What you can do with this tool

Fix a sideways photo

Phone photos sometimes save with incorrect orientation. Use Rotate CW or CCW to physically fix the pixels so every app and device shows it correctly.

Crop for Instagram

Pick the Instagram Post (1:1), Instagram Portrait (4:5) or Instagram Story (9:16) preset, drag to frame your subject and download at the right ratio.

Cut to exact dimensions

Type the exact width and height in pixels. Useful for app icons, passport photos, or any platform that requires a specific pixel size.

Straighten a crooked horizon

Use the Straighten slider to rotate up to 15 degrees and correct a tilted photo, then drag the crop box in to trim the empty corners before downloading.

Mirror a selfie

Front cameras capture a mirrored image. The Flip H button reverses it so text in the background reads correctly.

Crop a YouTube thumbnail

The YouTube Thumbnail preset locks to 16:9. Drag to frame your subject and download as JPEG for fast upload.

Cropping well is harder than it looks

Most people treat cropping as a mechanical step. Drag a box, cut off the edges, done. But cropping is actually one of the most meaningful decisions you make with an image. What you include and what you leave out completely changes how a viewer reads a photo. A portrait cropped tight to the face feels intense and personal. The same photo cropped wider to show context feels documentary. Neither is wrong. They're just different images making different statements.

The aspect ratio is often what drives the crop decision, not the other way around. Instagram's square format (1:1) forces you to think about centering and symmetry. The portrait format (4:5) gives you more vertical space but less horizontal. The YouTube thumbnail ratio (16:9) is wide and demands a strong horizontal composition. Understanding the ratio you're cropping to before you start dragging saves a lot of back-and-forth.

The rotation problem that catches everyone out

Phone cameras embed orientation data in the EXIF metadata rather than physically rotating the pixel data. This means the image file itself is actually sideways or upside down, and the phone just tells every app "display this rotated 90 degrees." Most apps respect that instruction and show the image correctly. Some don't. Government portals, older software, and many upload systems ignore the orientation tag entirely, and your portrait shows up as a landscape on the other end.

The fix is to physically rotate the pixels, not just update the metadata tag. When you use the Rotate CW or Rotate CCW buttons here, that's exactly what happens. The pixel data itself is rewritten in the correct orientation. Whatever system receives the file will display it correctly regardless of whether it reads orientation metadata or not.

Straightening vs rotating: two different tools for different problems

The 90-degree rotate buttons fix photos that were saved in the wrong orientation entirely. The Straighten slider is for something subtler: correcting a horizon that's slightly tilted, or fixing a scan that went into the scanner at a small angle. We're talking 1 to 5 degree corrections, not 90-degree flips.

When you straighten an image, the rotation leaves empty space at the corners of the resulting canvas, since a rotated rectangle no longer fills a rectangular frame. This tool does not automatically calculate and apply a crop that excludes those corners for you. After straightening, drag the crop box handles inward so your selection sits fully inside the rotated content, then check the result before downloading. If the tightened crop leaves you with a smaller image than you need, the resize tool can scale it back up to the dimensions you need.

Common cropping mistakes

Assuming straightening automatically trims the empty corners

It doesn't. Rotating for a straighten correction leaves empty space at the corners, and the crop box isn't automatically recalculated to exclude it. Drag the crop handles inward after straightening, then check the preview before downloading.

Expecting AVIF or HEIC output

Download formats here are JPEG, PNG or WebP only. Uploading an AVIF or HEIC file defaults the output to JPEG, since neither AVIF nor HEIC is available as a download option.

Trying to adjust WebP quality

The quality slider only controls JPEG output. WebP downloads always use the browser's default quality, there's nothing to adjust for WebP on this page.

Uploading a HEIC file and assuming it will always work

HEIC support depends on your browser's native image handling rather than a dedicated decoder. If a HEIC upload doesn't load, convert it to JPEG or PNG first.

Clicking Preview crop expecting it's required to download

It's optional. Download applies whatever crop selection is currently set, whether or not you've opened the preview panel first.

Frequently asked questions

How do I crop an image to an exact pixel size?

After uploading your image, type the width and height in pixels into the exact size fields in the sidebar. The crop box will snap to those dimensions. You can then drag the box to select the area you want to keep and click Download.

Can I rotate my image before cropping?

Yes. Use the CW (clockwise) and CCW (counter-clockwise) buttons to rotate the image in 90 degree steps. The crop box adjusts automatically. You can also use the Straighten slider for fine corrections up to 15 degrees in either direction.

Are there presets for Instagram, YouTube and other social media?

Yes. The sidebar includes standard aspect ratios (1:1, 4:3, 16:9, and others) plus a Social Media section with named presets for Instagram Post, Instagram Portrait, Instagram Story, YouTube Thumbnail, Facebook Cover, Twitter Header, LinkedIn Banner and LinkedIn Post.

What output formats can I download in, and which one is used by default?

You can download as JPEG, PNG or WebP. If you uploaded a PNG or WebP, that same format is selected by default. For any other upload, including JPEG, AVIF or HEIC, JPEG is selected by default, since AVIF and HEIC aren't available as download formats here. You can change the output format at any time before downloading.

Does cropping reduce image quality?

Cropping itself does not reduce quality, it only removes pixels, the remaining pixels are untouched. If you save as JPEG, there will be some compression, but the quality slider defaults to 90 which is visually lossless for most images.

Can I control the quality when downloading as WebP?

No, the quality slider only appears for JPEG output. WebP downloads use the browser's default encoding quality, there's no adjustable quality parameter for WebP on this page. If you need control over WebP file size, export as JPEG or PNG here and convert separately with a dedicated WebP converter.

What does the Straighten slider do?

The Straighten slider rotates the image by up to 15 degrees in either direction for correcting a slightly tilted horizon or crooked scan. Rotating a rectangular image by a small angle naturally leaves empty space at the corners of the resulting canvas.

How do I remove the empty corners that appear after straightening?

Manually. After straightening, drag the crop box handles inward so the selection sits fully inside the rotated image, away from the empty corners, then download. This tool does not automatically calculate and apply an inscribed crop for you, so it's worth checking the preview before downloading a straightened image.

Does EXIF or GPS data survive cropping?

No. The image is decoded and re-drawn onto a canvas, then re-encoded on download, so EXIF metadata, including GPS location, does not carry over to the downloaded file.

Is my image uploaded to a server?

No. Everything happens in your browser using the HTML5 Canvas API. Your image never leaves your device. You can disconnect from the internet after loading the page and the tool still works completely.

Do I need to click Preview before I can download?

No. Preview crop is optional, it just shows you what the final result will look like before committing. Clicking Download applies the current crop selection directly, whether or not you've previewed it first.

Can I crop more than one image at once?

This page handles one image at a time. If you're processing a batch, you'll need to run each image through separately here.

Can I upload a HEIC photo from my iPhone?

HEIC is listed as an accepted format, but this tool relies on your browser's native image support to open it rather than a dedicated HEIC decoder. Support can vary by browser, Safari tends to handle HEIC reliably, others may not. If your HEIC file doesn't load, convert it to JPEG or PNG first using the HEIC converter, then crop the converted file here.
