Convert
Crop to any ratio, privately
Crop an image to a preset ratio (square, widescreen, story) keeping the framing you choose, entirely locally.
For the best results: Pick the ratio your platform needs (square for profiles, 9:16 for stories) then choose whether to keep the center, top, or bottom of the frame.

What is Image Cropper?
Image Cropper is a free file converter that crops an image to a preset ratio (square, widescreen, story) with center, top, or bottom framing. Each image is decoded and re-encoded by your own browser's graphics engine, so your photos are never uploaded to a server. There is no queue, no watermark, and no account to create, and it keeps working with your connection off.

See it in action
A tall phone photo needs to become a square profile picture without stretching.
What you drop in
portrait.jpg (400 x 800), crop 1:1, keep Top
What you get
portrait-square.jpg at 400 x 400 keeping the top of the frame, verified in testing with a color-banded image where the top band stayed and the bottom was cropped away.
Tip: The Keep setting decides which part survives: Top for faces in portraits, Center for products, Bottom for signatures at the foot of a page. Story 9:16 and Widescreen 16:9 cover the common social sizes without any math.
Use cases
What people use it for
Crop a landscape photo to a square for a profile picture without opening heavy editing software

Social media manager
Reframes one master photo into square, widescreen, and story versions for every platform in a campaign

How it works
- 1Choose your files. They open in your browser, not on a server.
- 2Your device converts, compresses, or resizes them locally, with no upload.
- 3The converted files download straight back; nothing is kept anywhere.
Tips for the best results
- Pick the framing position based on where your subject sits, not habit; center is not always right
- Crop the largest original you have, so the surviving region keeps plenty of resolution
- For story crops of landscape photos, expect heavy trimming; check the subject survives the narrow band
- Make all platform versions from the same master image so colors stay consistent across posts
- Preview before downloading, since a crop cannot be widened again afterwards
FAQ
Frequently asked questions
How does cropping to a ratio actually work?
The tool computes the largest rectangle of your chosen proportions that fits inside the photo, then discards everything outside it. Cropping a 4000 by 3000 photo to square, for instance, keeps a 3000 by 3000 region and trims 500 pixels from each side. Nothing is stretched or squashed; pixels are only removed, which is why subjects never look distorted afterwards.
Append to the FAQ answer: "And when a crop trims the sides instead, as a tall story cut from a landscape photo does, the Left and Right options work the same way across the width."
They decide which slice of the photo survives. Center framing trims equally from both ends, which suits subjects in the middle. Top framing keeps the upper portion, the right choice for portraits where faces sit high in the frame. Bottom framing preserves the lower part, useful when the subject is a product on a table or text near the base of the image.
Is my photo sent anywhere when I crop it?
The crop is calculated and applied on your device, full stop. No copy of the original or the result touches a server, which matters more for cropping than people realize: the discarded region of a photo often contains exactly the private detail someone wanted removed. Here, both the kept and trimmed portions exist only in your browser's memory until you close the tab.
Which aspect ratio should I use for which platform?
Square, 1:1, remains the safe choice for profile images and feed posts. Widescreen, 16:9, matches YouTube thumbnails, presentation slides, and most website banners. Story format, 9:16, is the tall ratio used by Instagram Stories, Reels, and TikTok. Choosing the ratio before you shoot, or at least before you crop, saves the frustration of platforms auto-cropping your image badly.
Does cropping reduce the quality of my image?
The pixels that remain are untouched, so there is no compression loss from the crop itself. What does change is the total resolution: cutting a tall story crop from a wide landscape photo can discard most of the original pixels. If the remaining region is small and you display it large, softness comes from having fewer pixels, not from anything the cropper did to them.
How do I crop a picture without stretching it?
Use a ratio-based cropper rather than resizing. Cropping removes pixels outside the target rectangle while leaving the rest untouched, so proportions inside the frame never change. Stretching happens when software resizes an image to new proportions instead of trimming, which is what distorts faces and makes circles turn oval.
What aspect ratio is an Instagram story?
Stories use 9:16, a tall portrait rectangle that fills a phone screen, and the same shape serves Reels and TikTok. Cropping a standard landscape photo to 9:16 keeps only a narrow vertical band, so choose top, center, or bottom framing carefully to make sure the subject lands inside the surviving slice.
Is it an AI tool that decides how to crop my photo?
No, there is no automatic subject detection involved. The crop follows simple geometry from the ratio and framing position you pick, which makes the result completely predictable: the same settings always produce the same crop. You stay in control of the framing, it happens instantly, and the photo never leaves your device.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
