Crop Image for Social Media

Crop any photo to the exact size YouTube, Instagram, X, or Facebook wants — drag to position, zoom to fit. Everything happens in your browser and your image is never uploaded anywhere.

2026 recommended sizes by platform

Every platform crops or scales your picture to its own frame. If you upload the wrong shape, the platform decides what gets cut off — often a face or a title. Cropping to the exact size first keeps you in control.

Why crop instead of stretch?

Stretching a photo to a new shape squashes or elongates everything in it — faces get wider, text gets distorted, and the result looks unprofessional at a glance. This tool uses cover-fit cropping instead: the photo is scaled just enough to fill the frame completely, then you drag and zoom to choose which part shows. Nothing is distorted; you simply pick the best window onto your original picture.

The download is rendered at the preset's exact pixel size (for example a true 1280×720 file for YouTube), so platforms won't re-crop or upscale it. The circular profile option saves a PNG with transparent corners, so it looks right on any background.

What cropping costs, in pixels

Cropping is subtraction, and the arithmetic is worth doing before you commit. Keep half the width and half the height and you are left with a quarter of the pixels: a 4000 × 3000 photo cropped to a centre square at half size comes out 2000 × 1500, which is 3 megapixels of the original 12. Crop tightly and resolution falls away far faster than the visible frame suggests.

That matters in two places. On screen it usually does not — 2000 px wide is generous for any web layout. In print it does, because print wants roughly 300 pixels per inch, so a hard crop that looks perfect on a phone can be too soft on a page.

Everything outside the frame is discarded when you download, and nothing can bring it back; upscaling later invents detail rather than restoring it. Your original file is untouched, so the safe habit is to crop a copy and keep the full frame.

The preview is scaled; the download is not

The preview is fitted to your screen, so what you see is smaller than what you get. The download is rendered at the preset's exact pixel size — a true 1280 × 720 file for a YouTube thumbnail — however large or small the preview happens to be in your browser window. If your photo is smaller than the target it is scaled up to fill the frame and will look slightly soft; the fix for that is a larger original, not a different setting.

Frequently asked questions

Is my photo uploaded to your server?

No. The image is opened, cropped, and saved entirely inside your browser using its built-in canvas — it never leaves your device.

Will the downloaded file be the exact pixel size shown?

Yes. The preview is scaled to fit your screen, but the download is rendered at the preset's full resolution — e.g. exactly 1280×720 pixels for a YouTube thumbnail.

Why is the circular profile picture a PNG?

Only PNG supports transparency. The area outside the circle is saved as transparent pixels, so the round crop keeps its shape on any background. JPEG would fill the corners with a solid color.

What if my photo is smaller than the preset?

It will be scaled up to fill the frame, which can look slightly soft. For crisp results, start from a photo at least as large as the target size.
