Crop Image lets you cut away unwanted edges and keep only the part of the picture you need. Drag the crop box or pick a ratio such as 1:1 or 16:9 — your photo is cropped in your browser and never uploaded.
How to crop an image
- Click "Choose image" or drag and drop a picture into the box.
- Pick a ratio (Free, 1:1, 4:3, 16:9…) if you need a fixed shape.
- Drag the box to move it and drag the round handle to resize it, or type exact pixel values.
- Click "Crop image" and then "Download image".

Frequently asked questions
Are my files uploaded to a server?
No. ZentaPDF processes your files inside your own browser using JavaScript. Nothing is uploaded, so nobody else can see your documents — not even us.
Which ratio should I use for social media?
1:1 (square) suits Instagram posts and profile photos, 16:9 suits YouTube thumbnails and wide banners, and 9:16 suits Stories, Reels and Shorts.
Can I crop to an exact size in pixels?
Yes. Type the Left, Top, Width and Height values below the image to set the crop area to the exact pixel.
Does cropping reduce the quality?
No. The pixels you keep are not resized. JPG and WebP images are saved at high quality (92%).
Is it really free? Do you add a watermark?
Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
