Crop an Image Online

Cropping is the simplest, most useful edit you can make to an image: you keep the part that matters and throw away the rest. It fixes crooked framing, removes distractions at the edges, and reshapes a photo to fit wherever it’s going — a square avatar, a 16:9 video thumbnail, a passport photo, or a banner.

This guide shows you how to crop an image properly, how to hit an exact pixel size, and how to choose the right shape and file format. You can do all of it with the free cropper at the top of this page — the cropping runs entirely in your browser.

What cropping does (and why aspect ratio matters)

Cropping removes pixels from the outside of an image. It does not stretch or squash anything, so it never distorts faces or text — it only changes which part of the picture you keep and the overall shape.

That shape is the aspect ratio: the relationship between width and height. A few you’ll meet constantly:

• 1:1 — a perfect square. Profile pictures, product photos, Instagram posts.
• 4:3 and 3:2 — classic photo shapes from cameras and phones.
• 16:9 — widescreen. YouTube thumbnails, presentation slides, video.
• 9:16 — tall. Phone wallpapers, Stories, Reels, TikTok.

Picking the right ratio first means the platform you’re posting to won’t crop your image again (and cut off someone’s head).

How to crop an image online (step by step)

1. Open your image. Drag a photo onto the tool above, click Choose image, or paste one from your clipboard.
2. Pick an aspect ratio, or leave it on Free to crop to any shape.
3. Drag the crop box to frame what you want, and drag the handles to resize it. The rule-of-thirds grid helps you line up a balanced composition.
4. Straighten or rotate if needed — nudge the straighten slider to fix a tilted horizon, or rotate in 90° steps. Flip horizontally for a mirror image.
5. Choose your output — format (PNG, JPG, or WebP) and, if you need it, an exact output width.
6. Click Download. Your cropped image saves straight to your device.

Crop to an exact size in pixels

Sometimes you don’t just need a shape — you need an image that is exactly 800×800, or 1280×720, or whatever a form or upload demands.

To do that:

1. Set the aspect ratio to match your target (for 1280×720 that’s 16:9; for a square that’s 1:1).
2. Position the crop box over the part of the image you want.
3. In Output width, type your target width in pixels. The height updates automatically to keep the ratio, so you get the precise dimensions with no guesswork.

The tool shows the native size of your crop (how many original pixels it contains). If you keep the output at or below that number, your image stays pixel-sharp. Going larger is possible but means upscaling, which can look soft.

Common aspect ratios and where to use them

Ratio	Good for
1:1	Profile photos, avatars, product shots, Instagram
4:3	Everyday photos, slides, some print sizes
3:2	DSLR/mirrorless photos, classic prints (4×6)
16:9	YouTube thumbnails, widescreen slides, video
9:16	Stories, Reels, TikTok, phone wallpapers

If you’re unsure, crop a little looser than you think you need — you can always crop again, but you can’t add back pixels you’ve removed.

Circle and rounded crops

For avatars and logos, a circle or rounded-corner crop looks far more polished than a hard rectangle. In the tool, choose the Circle or Rounded mask before downloading.

One thing to know about transparency: a circle has corners, and something has to fill them.

• Export as PNG or WebP to keep those corners transparent — ideal when the image sits on a coloured background.
• Export as JPG if you need a solid background; pick the Background colour and the corners fill with it (JPG can’t store transparency).

Choosing PNG, JPG, or WebP for the result

• JPG — best for photographs. Smallest files, no transparency. Use a quality around 80–90 for a result that looks identical to the original at a fraction of the size.
• PNG — best for graphics, logos, screenshots, and anything with sharp edges or transparency. Lossless, but larger.
• WebP — the modern all-rounder. Usually smaller than both JPG and PNG at the same quality, with transparency support. Great for the web; double-check it’s accepted wherever you’re uploading.

Is it safe? Where does the cropping happen?

The cropping itself is done in your browser using the Canvas API — the cropped file is created on your own device. That’s faster than tools that round-trip your photo through a server just to crop it.

Tips for print vs the web

• For the web, think in pixels: match the size the image will actually display at, and prefer JPG or WebP to keep pages fast.
• For print, you usually need more pixels than the screen shows — a 4×6 print at 300 DPI needs about 1200×1800 pixels. Crop from the highest-resolution original you have, and don’t upscale a small image to “make it bigger” for print; it’ll look soft.

Crop once, crop from the best original, and pick the shape before you post. With those three habits, the tool above does the rest.
