The image cropper gives you a visual selection handle over any uploaded image. Drag the corners to frame the area you want to keep, or pick a preset aspect ratio (1:1 square, 4:3 classic photo, 16:9 widescreen, 3:2 DSLR) to enforce an exact shape. The selection is pixel-accurate and is shown with a live dimensions readout as you drag.
Typical uses include making profile pictures square, preparing thumbnails for a CMS, isolating a subject from a larger scene, or creating a banner image at exactly 1200×400 without any squish. Output is saved in the original format so you can crop lossless PNGs without introducing JPG compression.
Cropping runs entirely in your browser on a hidden canvas. Your image is not uploaded, so you can safely crop screenshots containing private information, personal photos, or any other sensitive content.
Image Cropper — Frequently Asked Questions
How do I crop an image to a specific aspect ratio?
Pick a preset — 1:1 for squares, 4:3 or 3:2 for classic photos, 16:9 for widescreen, 9:16 for vertical stories. The selection box locks to that ratio so you can drag to reframe without distorting. For exact pixel targets (like 1200×400), use free-form mode and type the dimensions into the coordinate boxes.
What size should I use for a profile picture?
1:1 square at 400×400 covers most platforms (LinkedIn, Twitter, GitHub). Instagram uses 320×320 for display but accepts up to 1080×1080 — upload at the higher size for Retina sharpness. Pick the 1:1 preset, frame your face, crop, and you're done.
Does cropping an image lose quality?
No. Cropping just discards pixels outside the selection — the kept pixels are bit-identical to the source when the output format matches the input. The only way quality changes is if you switch to a lossy format (JPG, WebP) on export. Keep PNGs as PNGs for fully lossless crops.
What image formats can I crop?
JPG, PNG, WebP, AVIF, HEIC, GIF, and BMP. The output is saved in the same format by default so PNGs stay lossless, but you can switch on export — for example, crop a HEIC from your iPhone and save the result as a universally-openable JPG.
Can I undo a crop?
The original image is never modified — you can re-draw the selection as many times as you want before downloading. If you've already downloaded, just re-upload the source and re-crop.
Is my image uploaded to any server?
No. Cropping runs on a hidden canvas in your browser. Your image never leaves your device, so it's safe to crop screenshots with private information, personal photos, or anything else sensitive.
