Crop Image
Drag, frame, download. Cropping happens on your device, so your photo never touches a server.
🔒 Your files never leave your device
Crop an image online in seconds: cut away clutter, straighten the focus onto your subject, or trim a screenshot down to just the part that matters. The crop is computed entirely in your browser, so the picture never leaves your device. That makes it fine to crop documents, receipts and personal photos here.
Drag the corners of the crop box freely, or snap to preset ratios such as 1:1 for profile pictures, 16:9 for video thumbnails and covers, and 4:5 for portrait posts. The dimensions readout shows the exact pixel size of your selection as you drag.
Because nothing is re-encoded until you export, you can adjust the frame as many times as you like before committing.
How to crop an image
- Drop your image into the tool or tap to choose one.
- Drag the crop box over the area you want to keep.
- Optionally pick a fixed ratio like 1:1, 4:3 or 16:9 to snap the box.
- Fine-tune the edges until the framing looks right.
- Click Crop, check the preview, and download the result.
Crop sizes that platforms actually want
Square 1:1 covers most avatars and grid posts. 16:9 fits video thumbnails, presentation slides and blog headers. 4:5 vertical is the tallest crop most social feeds display without trimming. If a site lists an exact pixel requirement, crop to the right ratio here first, then resize; ratio decides the shape, resizing decides the size.
One habit worth keeping: crop before you compress. Trimming pixels away first means the compressor has less to work on and the final file comes out smaller.
What cropping actually does
Cropping keeps a rectangular region of your image and discards everything outside it. The pixels you keep are the original pixels, untouched — cropping never rescales or re-compresses the part you're keeping, so a crop of a sharp photo is exactly as sharp as the source.
Because you're removing pixels, the output has smaller dimensions and a smaller file than the original. That makes cropping a quiet way to trim file size too: cut away empty margins or background and the image gets lighter as well as better framed.
How the crop is computed in your browser
As you drag the box, the tool is just tracking coordinates; nothing is changed yet. Only when you click Crop does it draw the selected region onto an HTML Canvas and export it, all in JavaScript on your device. That's why you can reframe endlessly with no quality cost — re-encoding happens once, at the end.
There is no upload and no server step, so the crop is instant even on a phone. The file on your disk is never modified; you're always exporting a fresh copy, so the original is safe if you want to start over.
Cropping private images stays private
Screenshots often catch more than you want to share — a name in a sidebar, an account balance, a stray browser tab. Cropping them down is a privacy task in itself, and doing it in a tool that uploads your file would defeat the point.
Here the crop runs entirely in your browser, so the image is never transmitted anywhere. You can safely trim IDs, tickets, boarding passes and receipts, keeping only the part you mean to send and leaving everything else on your device.
Aspect ratio, without the jargon
An aspect ratio is just the shape of the rectangle — its width compared to its height — regardless of pixel size. 1:1 is a perfect square, 16:9 is a wide landscape rectangle, and 4:5 is a tall portrait one. Locking the crop box to a ratio guarantees the shape while you decide how much of the image to keep.
Freeform cropping lets you draw any rectangle, which is ideal for trimming a screenshot to arbitrary edges. Use a locked ratio when a platform is fussy about shape — profile pictures, video thumbnails, feed posts — so the result fits its frame without the site adding its own awkward crop.
Fixing common cropping mistakes
If your subject ends up too tight or slightly cut off, remember you can only crop inward — you can't add space back. Leave a little breathing room around faces and important edges, especially for platforms that overlay buttons or text on part of the image.
If the cropped file looks low-resolution, the culprit is usually cropping a small region out of an already-small image; there simply aren't many pixels left. Start from the highest-resolution original you have. And if a crop looks the wrong shape for a site, pick the matching ratio preset before dragging rather than eyeballing it.
Crop first, then resize
Cropping and resizing solve different problems, and the order matters. Crop to choose what stays in frame and to fix the shape; resize afterward to hit a platform's exact pixel dimensions. Doing it the other way round often forces you to resize twice.
Compared with online croppers that upload your file, the practical wins here are speed and privacy: no waiting for an upload, no copy left on a server, and no limit on how many images you crop. The pixels you keep come through at full quality every time.
Frequently asked questions
Is this crop tool free?
Yes, entirely free. No account, no watermark, no limit on the number of images you crop.
Is my photo uploaded when I crop it?
No. The crop is done locally in your browser. The image file never leaves your device, which is exactly why it's safe to crop IDs, tickets or private pictures here.
Can I crop to an exact aspect ratio?
Yes. Choose a preset like 1:1, 4:3, 4:5 or 16:9 and the crop box locks to that shape while you drag. For a fully custom shape, leave it on freeform.
Does cropping lower image quality?
The pixels you keep are untouched, so the cropped area stays as sharp as the original. You're only discarding the parts outside the box.
What file types can I crop?
JPG, PNG and WebP are supported. Transparent PNGs keep their transparency after cropping.
Does it work on a phone touchscreen?
Yes. Drag the crop handles with your finger on iPhone or Android. Pinch-zoom the page if you need finer control over a small area.
