Crop Image
Crop images to exact dimensions or aspect ratios. Preview before saving.
Crop an image to a precise aspect ratio or freeform shape with a live preview. Pick a preset like 1:1 for a square, 4:5 for a tall portrait post, or 16:9 for video and banners, then drag the box to frame exactly what you want. The selection updates in real time so you see the final composition before you commit.
The crop happens entirely in your browser on your own device. No upload, no signup, and the original file never leaves your computer or phone. Drag, adjust, and download in seconds.

About Crop Image
Crop images to an exact aspect ratio or freeform selection with a live preview. Lock to 1:1, 4:5, 16:9, and more for social posts and thumbnails. Runs entirely in the browser.
How to use the Crop Image
- 1
Load your photo
Drop in a JPG, PNG, or WebP. It appears with an adjustable crop box overlaid on top.
- 2
Pick a ratio
Choose 1:1, 4:5, or 16:9 to lock the box to that shape, or select freeform to drag any rectangle you like.
- 3
Frame the shot
Drag the box to reposition and pull the handles to resize. The live preview shows precisely what will be kept.
- 4
Export the crop
Confirm the selection and download. Only the area inside the box is saved; everything outside is removed.
Aspect ratios that match real platforms
Each preset maps to a place these shapes are actually used. 1:1 is the classic square for profile grids and product tiles, commonly exported at 1080×1080. 4:5 is the tallest shape Instagram allows in the feed (1080×1350) and takes up the most screen space on a phone, which is why it tends to get more attention.
16:9 is the widescreen standard for YouTube thumbnails, video frames, and website hero banners, usually at 1920×1080. Picking the right ratio before you post means the platform will not crop your image again and cut off something important.
Cropping vs resizing
These solve different problems. Cropping changes what is in the frame by cutting away parts of the picture, so the subject can be recentered or a distracting edge removed. The pixels you keep are untouched and stay sharp.
Resizing changes the dimensions of the whole image without removing any content. If you need a 1:1 square from a wide photo, crop it rather than squashing it, because forcing a wide image into a square by resizing distorts faces and straight lines. Many workflows crop first to set the composition, then resize to hit an exact pixel target.
Quick tips
- ✓Use 4:5 for feed posts to claim the most vertical space on mobile screens.
- ✓Leave a little breathing room around your subject; platforms sometimes shave the edges on display.
- ✓For profile pictures, crop to 1:1 first since nearly every avatar slot expects a square.
- ✓Freeform is ideal for trimming scanned documents or screenshots down to just the useful area.
- ✓Crop to set composition, then run the result through a resizer if you also need a specific pixel size.
Frequently asked questions
Does cropping reduce quality?
No. Cropping only removes pixels outside the selection — the remaining pixels are unchanged.
Can I crop to a specific aspect ratio?
Yes — pick a preset like 1:1 or 16:9 and the selection stays locked to that ratio as you drag.
What about transparency?
PNG transparency is preserved. Save as PNG to keep transparent areas.
Does cropping lower the image quality?
No. Cropping keeps the original pixels inside your selection at full quality. The image only gets smaller in pixel count because you removed area, not because anything was recompressed or blurred.
Can I crop to a ratio that is not in the presets?
Yes. Switch to freeform and drag any rectangle you want. The presets are shortcuts for the most common shapes, but freeform lets you frame to any proportion.
What happens to the parts outside the crop box?
They are permanently removed from the downloaded copy. Your original file on disk is untouched, so you can always reopen it and crop differently.
