How to crop an image online
1
Add your photo
Drag an image onto the box above or click to choose a file. JPG, PNG, WebP, GIF, BMP and HEIC are all supported, and the file stays on your device.
2
Drag to crop
Move the crop box and pull its handles to frame exactly what you want to keep. Pick a ratio preset (or a social-media size) to lock the proportions perfectly.
3
Download
Choose PNG or JPG and click Download. The image is cut at full resolution with no watermark — done in a second, no sign-up needed.
Crop to exact social-media sizes
Every platform has its own ideal frame, and posting a wrongly-shaped image means an awkward auto-crop that chops off heads or logos. The presets on this page lock the crop box to the exact proportions each platform expects, so you frame the shot yourself instead of letting the app decide:
Preset
Aspect ratio
Best for
Instagram Post
1:1 (square)
The classic feed square and most profile pictures.
Instagram Portrait
4:5
The tallest image the feed allows — takes up the most screen space.
Instagram Story / Reel
9:16
Full-screen vertical stories, Reels and TikTok.
YouTube Thumbnail
16:9
Video thumbnails, slide decks and widescreen banners.
Facebook Cover
~2.7:1
Profile and page cover photos.
X / Twitter Header
3:1
The wide banner at the top of an X profile.
LinkedIn Banner
4:1
Personal and company page background banners.
Need a non-standard shape? Type any width-to-height pair into the custom ratio box and click Lock — useful for print sizes, website hero images or app icons.
Crop an image to a square
Making a square crop by eye is fiddly because a few stray pixels ruin a profile picture. Click the 1:1 preset (or Instagram Post) and the crop box locks to a perfect square: drag it over the part of the photo you want, resize it freely, and the width and height always stay equal. It's the fastest way to turn a rectangular photo into a clean square avatar for Instagram, WhatsApp, Discord, Slack or a forum, without stretching or distorting the picture.
Private by design — no upload
Unlike most online croppers, this tool never sends your image to a server. The moment you drop a file it is decoded and drawn onto an HTML canvas inside your own browser; the crop happens in memory and the download is generated locally. That means your photos — screenshots, ID documents, private pictures — stay completely on your device, the tool keeps working if your connection drops after the page loads, and there are no size limits beyond what your device's memory allows. It's the same privacy-first approach behind our HEIC to JPG converter and passport photo maker.
Will cropping reduce quality?
Cropping itself never lowers quality — it simply discards the pixels outside the crop box while the kept area stays at its original resolution. The only thing that affects quality is the export format:
PNG is lossless and preserves transparency, so it's perfect for logos, screenshots and graphics. Files are larger.
JPG uses adjustable compression — great for photos where a slightly smaller file matters. Keep quality at 90%+ for sharp results, or lower it to shrink the file for email and the web.
The output dimensions shown next to the Download button are the exact pixel size you'll get, so you always know what you're saving.
Crop image FAQ
How do I crop an image online for free?
Drop or select your photo above, drag the crop box and its handles over the part you want to keep, then click Download. Pick a preset like 1:1 to lock the proportions. It's free, needs no sign-up, adds no watermark, and the image is cropped entirely in your browser.
Does this image cropper upload my photos to a server?
No. Cropping happens 100% in your browser using the HTML canvas, so your photo never leaves your device and is never uploaded. That makes it safe for private screenshots and ID photos, and it works offline once the page has loaded.
How do I crop an image into a perfect square?
Click the 1:1 preset (or Instagram Post). The crop box locks to a square so you can drag it anywhere and resize it while keeping equal width and height — the quickest way to make a square profile picture without distorting the image.
Will cropping reduce the quality of my image?
No. Cropping only trims the pixels outside the crop box — the kept area stays at original resolution. Export as PNG for a lossless copy, or JPG with adjustable quality for a smaller file. Nothing is upscaled or re-compressed unless you lower the JPG quality.
What aspect ratios and social-media sizes can I crop to?
Freeform plus locked ratios (1:1, 4:5, 9:16, 16:9, 4:3, 3:2, 2:3, 3:4) and one-click presets for Instagram post and story, YouTube thumbnail, Facebook cover, X/Twitter and LinkedIn banners. You can also type an exact custom ratio to lock any proportion.
Which image formats does the cropper support?
It opens common formats your browser can read — JPG, PNG, WebP, GIF (first frame), BMP and most HEIC images on supported browsers — and lets you download the result as a PNG (lossless, keeps transparency) or a JPG with adjustable quality.
