Aspect ratios, crop sizes, and a free crop tool — right in the editor.
Cropping removes the outer parts of an image to change its framing or fit a specific aspect ratio — without distorting the picture. This guide covers when to crop, the common aspect ratios, how to crop without losing quality, and the fastest way to crop free in your browser.
| Use | Ratio | Size (px) |
|---|---|---|
| YouTube thumbnail | 16:9 | 1280 × 720 |
| Instagram post (square) | 1:1 | 1080 × 1080 |
| Instagram portrait | 4:5 | 1080 × 1350 |
| Story / Reel / TikTok | 9:16 | 1080 × 1920 |
| Facebook shared post | 1.91:1 | 1200 × 630 |
| X / Twitter post | 16:9 | 1600 × 900 |
| Profile picture | 1:1 | square |
Lock any of these ratios in the editor's crop tool, or drag a freeform crop box and apply.
There are three common reasons to crop: to fit a required aspect ratio (a YouTube thumbnail must be 16:9, an Instagram square is 1:1), to improve the framing by removing dead space or distractions and putting the subject where you want it, and to recompose a shot after the fact. Cropping removes pixels from the edges — it changes the shape and framing, unlike resizing (which scales the whole image) or compressing (which only shrinks the file).
Start from the largest original. Cropping throws away pixels, so a small image leaves you with even fewer. Begin from the highest-resolution version you have.
Don't enlarge after cropping. If you crop tightly and then scale the result back up, it gets blurry. Crop to the size you actually need.
Lock the aspect ratio. Set the exact ratio for your target (16:9, 1:1, 9:16) so the crop fits the platform without further adjustment. The editor's crop tool lets you lock a ratio, enter custom dimensions, or rotate while you crop.
Each platform expects a specific shape. YouTube thumbnails are 16:9. Instagram uses 1:1 squares, 4:5 portraits, and 9:16 for Stories and Reels. TikTok is 9:16, and profile pictures are square (1:1). Cropping to the right ratio before you upload stops the platform from cropping it for you — and cutting off the wrong part of your image.
These three are easy to mix up. Cropping removes part of the image to change framing or ratio. Resizing changes the pixel dimensions of the whole image. Compressing lowers the file size without changing dimensions. They work together: crop to the right shape, resize to the right dimensions, then compress to shrink the file. To resize and convert in one place, use Image Studio.
The fastest way is right in your browser: open the free editor, upload your image, choose the crop tool, drag the crop box (or set an exact ratio or dimensions), and apply. Everything runs locally — your image is never uploaded. From there you can add text, resize, or remove the background in the same place.
