Image Crop
Crop an image by typing pixel values or dragging the box, then save as PNG, JPEG or WEBP. Lock the position and size to cut other images at the same coordinates.
Cropping and saving run entirely in your browser. "Crop & save" downloads the result immediately.
Crop coordinates by ratio
These numbers are for a 1280×720 image cropped from the centre. X is (source width − crop width) ÷ 2. If you plan to reuse one image in several ratios, look at the “width kept” column first.
| Ratio | Common use | Size on 1280×720 | Centred X | Width kept |
|---|---|---|---|---|
| 16:9 | YouTube thumbnails, landscape video | 1280 × 720 | 0 | 100% |
| 1:1 | Profile pictures, square tiles | 720 × 720 | 280 | 56.3% |
| 4:5 | Portrait posts | 576 × 720 | 352 | 45.0% |
| 9:16 | Shorts, Reels and other vertical screens | 405 × 720 | 437 | 31.6% |
A 9:16 crop keeps less than a third of the width. Cropping a 16:9 thumbnail from the centre really does cut off a title placed on the left, so keep titles and faces inside the central 405 px — about 32% of the width — when an image must work in several ratios.
How to use
- Drop an image into the window or click to open it. Drag on the preview to set the area, or pick a ratio preset (1:1, 4:3, 16:9, 9:16 and more).
- For exact values, type X, Y, width and height. The centre button positions the chosen size in the middle, and values are clamped so the area stays inside the image.
- Choose a save format and download. PNG stores the cropped pixels losslessly, while JPEG and WEBP re-compress at the quality you pick. Turn on the lock to keep the same coordinates and size for the next image.
Thumbnail and social image tips
- Crop by content, not by centre: don't stop at choosing a ratio. Moving X so the key text or face fits completely changes the result of the same 1:1 crop.
- Define a safe area first: when an image will be reused in several ratios, designing with the key elements inside the central third saves re-cropping later.
- Leave the edges clear: duration badges, captions and profile icons cover the corners on many platforms, so keep text away from the edges.
- YouTube thumbnail specs: the official help recommends 16:9 at 3840×2160, a minimum width of 640 px, JPG or PNG, and under 2 MB when uploading from mobile (50 MB from desktop), as checked in September 2026. Photographic thumbnails easily exceed that as PNG, so prefer JPEG.
- Don't enlarge small sources: cropping can only cut pixels, never add them. If the crop came out small, find a larger original rather than scaling it up.
Frequently asked questions
Does choosing a ratio also set the pixel size?
No — ratio and pixel size are separate settings. Picking 16:9 does not make the result 1280×720; it depends on the area you dragged. Type the width and height when exact pixels matter. For example, cropping 1280×720 from the centre of a 1600×1200 image gives X=160 and Y=240.
Does cropping reduce quality?
The crop itself keeps the original pixels, so quality is unchanged. The save format is what matters: PNG is lossless, while JPEG and WEBP re-compress at the chosen quality, so zoom in around text to check. Enlarging the result afterwards only makes it softer; it cannot add detail.
Can I crop several images to the same size?
Yes. With the lock on, X, Y, width and height carry over to the next image, so you can cut a series to the same format. If a new image is smaller than the previous one the area shrinks to fit, so check the numbers before saving.
Is my original file modified?
No. The original is left untouched and the crop is downloaded as a new file. Nothing is uploaded and all processing happens inside your browser, so unpublished artwork and personal photos stay private. You can also re-crop the same source at different ratios as often as you like without degrading it.
What ratio works best for a profile picture?
Most services display profile images as a circle or a square, so 1:1 is the safe choice. Adjust X and Y so the face sits in the middle and leave a little space above the head and below the shoulders. Because circular masks cut the corners, avoid placing anything important near the edges.
