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° and correct a tilted photo. The white corners are automatically removed on download.

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, and the EXIF tag is updated to match. Whatever system receives the file will display it correctly regardless of whether it reads 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 introduces white triangular corners at the edges. This tool handles that automatically by calculating the largest crop that fits inside the rotated image and applying it on download. You don't see white corners in the downloaded file. What you see is a clean, slightly tighter version of the straightened image. If that crop is too tight for your use case, the resize tool can scale it back up to the dimensions you need.

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° steps. The crop box adjusts automatically. You can also use the Straighten slider for fine corrections up to 15° 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, etc.) plus a Social Media section with named presets for Instagram Post, Instagram Story, Instagram Portrait, YouTube Thumbnail, Facebook Cover, Twitter Header, LinkedIn Banner and LinkedIn Post.

What output formats can I download in?

You can download the cropped image as JPEG, PNG or WebP. The tool defaults to the same format as the image you uploaded. For JPEG, a quality slider lets you balance file size against visual quality.

Does cropping reduce image quality?

Cropping itself does not reduce quality because 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.

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.

What does the Straighten slider do?

The Straighten slider rotates the image by up to 15° in either direction for correcting a slightly tilted horizon or crooked scan. After straightening, the downloaded image is automatically cropped to remove the white corners that appear from the rotation.
