Crop images online, precisely and at full resolution
Cropping is the quickest way to improve a photo: it removes distracting edges, puts the focus on your subject and makes a picture fit the shape a platform expects. The Crop Image tool lets you drag a crop box over any JPG, PNG, WebP, GIF or BMP image, lock it to a ratio such as 1:1, 4:5 or 16:9, and download exactly that area.
The box works with a mouse, a trackpad or your finger, and the X, Y, width and height fields show the selection in real pixels, so you can also type an exact crop. The result is cut from the original full-resolution image — not from the smaller preview — and nothing is uploaded: the whole job happens in your browser.
How to use the Crop Image
- Drop an image on the upload area, click to choose one, or paste it with Ctrl+V.
- Pick an aspect ratio — Free, Original, 1:1, 4:3, 16:9, 4:5 and more. A fixed ratio places the largest possible box in the centre.
- Drag inside the box to move it, drag a corner or edge handle to resize it, or drag on the image outside the box to draw a new one.
- Fine-tune with the X, Y, Width and Height fields, measured in pixels of the original image. Press “Rotate left” or “Rotate right” first if the photo is sideways.
- Choose the format under “Save as” and press “Crop & download”.
Crop Image features
Touch-friendly crop box
Large handles on every corner and edge, rule-of-thirds guides, and pointer handling that behaves the same with a mouse, pen or finger.
Aspect ratio presets
Free, Original, 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3 and 4:5 — the shapes used by Instagram, YouTube, prints and phone screens.
Pixel-exact numbers
X, Y, width and height stay in sync with the box in both directions, so you can drag roughly and then type exact values.
Full-resolution output
The crop is taken from the original pixels, so a square cut from a 4000 × 3000 photo is a sharp 3000 × 3000 file.
Rotate in 90° steps
Turn sideways phone photos upright before you crop, without opening another tool.
Private and free
No upload, no sign-up and no watermark. The cropped file also leaves out EXIF metadata such as GPS location.
Which aspect ratio should you use?
An aspect ratio describes shape, not size: a 1:1 crop is square whether it is 500 or 5,000 pixels wide. Choose the shape here, then use the image resizer if a platform also wants an exact pixel size.
| Ratio | Common uses |
|---|---|
| 1:1 | Instagram and Facebook posts, profile pictures, product photos |
| 4:5 | Instagram portrait posts — the tallest shape allowed in the feed |
| 16:9 | YouTube thumbnails, presentations, TVs and monitors |
| 9:16 | Stories, Reels, Shorts and phone wallpapers |
| 4:3 and 3:4 | Most phone camera photos, tablets |
| 3:2 and 2:3 | DSLR and mirrorless photos, 4 × 6 inch (10 × 15 cm) prints |
| Original | Trim the edges while keeping the photo’s own shape |
Cropping tips for better photos
- Use the thirds: place the subject or the horizon on one of the guide lines inside the crop box rather than dead centre — it usually looks more natural.
- Leave room to look into: if a person faces left, keep more space on the left side of the frame.
- Avoid cutting at joints: crops that land exactly on knees, elbows or wrists look awkward; crop between them instead.
- Crop before compressing: removing unwanted background lowers the pixel count, so the image compressor reaches a smaller file with less quality loss.
- Watch the resolution: a heavy crop leaves fewer pixels. The size badge shows what you will get — for a sharp 1080 px Instagram post, keep the crop at least 1080 px wide.
Cropping vs resizing
Cropping removes part of the picture and leaves the remaining pixels untouched; resizing keeps the whole picture but changes how many pixels it has. To turn a landscape photo into a square profile picture you crop. To make a 4,000-pixel photo small enough for email you resize. Often you need both: crop to the right shape first, then resize.
For ID and visa photos, where the head must fill a set part of the frame, the passport photo maker adds official guides for you. To cut one picture into equal tiles for a grid post, use the image splitter.
Crop Image FAQ
How do I crop an image to a square?
Choose “1:1” in the aspect ratio row. The largest square that fits is placed in the centre; drag it to frame your subject and press “Crop & download”.
Does cropping reduce image quality?
No. The pixels inside the crop box are copied exactly from the original. Quality only changes if you save as JPG or WebP, which re-compress the result at a high 92% quality — choose PNG for a lossless copy.
Can I crop an image to exact pixel dimensions?
Yes. Type the X and Y position and the width and height in the number fields. They use the real pixels of your original image, and the crop box moves to match.
Does this image cropper work on phones?
Yes. The handles are sized for fingers, and dragging on the photo adjusts the crop instead of scrolling the page. Swipe outside the image to scroll.
Are my photos uploaded?
No. Cropping happens in your browser with the canvas API, so the image never leaves your device.
Why is my cropped image sideways?
Some older apps store rotation in metadata instead of turning the pixels. Press “Rotate left” or “Rotate right” before cropping, or straighten a photo by any angle with the rotate and flip tool.
