How do I crop a photo online?

Drop the image, drag a rectangle to set the crop area (or pick an aspect-ratio preset), then click Crop. The new image is ready to download with no quality loss for the cropped region.

Can I crop to Instagram, YouTube or A4 sizes?

Yes. Pick a preset like 1:1 (Instagram square), 9:16 (Instagram story / TikTok), 16:9 (YouTube thumbnail) or 1:√2 (A4) and the rectangle snaps to that ratio.

Will cropping reduce image quality?

No. Cropping just removes pixels — the pixels you keep are unchanged. JPG and WebP outputs are re-saved at quality 95 to keep the file small without visible loss; PNG is fully lossless.

Can I crop a JPG, PNG or WebP?

Yes. The cropper accepts JPG, PNG and WebP, and you can export to JPG, PNG or WebP independently of the input format.

Within the editor, yes — clear the rectangle and start again. After downloading, undo isn't possible (the cropped pixels are gone), so keep your original safe.

Are my photos uploaded?

No. Cropping happens entirely in your browser. Your photos never leave your device.

Is there a maximum image size?

There's no fixed limit — the practical cap is your device's memory. Phones can comfortably handle 12-megapixel photos.

Can I lock the aspect ratio?

Yes. Pick a preset (like 1:1 or 16:9) and the rectangle stays at that ratio while you draw or move it.

Does it work on iPhone and Android?

Yes. The cropper supports touch — drag your finger to draw the crop rectangle, then tap Crop.

Is the image cropper free?

Yes. Free, no signup, no watermark.

Good to know

Cropping is the most lossless edit there is: you are simply choosing which pixels to keep, and the ones inside the rectangle are untouched. That makes it the right first step for reframing a photo, straightening a composition, or hitting a required aspect ratio before you post. The eight handles let you refine an edge precisely, while dragging the whole rectangle repositions the frame without changing its size.

Aspect-ratio presets are the practical heart of the tool. Social platforms are strict about shape — 1:1 for an Instagram square, 9:16 for a story or TikTok, 16:9 for a YouTube thumbnail, and 1:√2 for A4 — and cropping to the exact ratio yourself means the platform will not do its own, less flattering crop on upload.

You can crop and change format in one pass, exporting to JPG, PNG or WebP regardless of what you dropped in. Because there is no undo after download, keep your original safe. When you need to fit exact pixel dimensions rather than a shape, hand off to Resize Image after cropping to the right proportions.
