Help and details
- Select an image. The editor opens right away.
- Drag the crop box (free, or lock a shape such as 1:1 or 16:9), and rotate, flip, straighten, or zoom if you need to.
- Set the size you want. The proportions are kept, so the picture is never stretched.
- Choose the format and quality, then press Download image. Your original file is not changed.
- The editor uses the open-source Cropper.js library. Phone photos stored sideways are turned upright first.
- On download, the crop is taken from your original full-size pixels in one step, never from the on-screen preview.
- Shrinking is done in gentle halving steps with high-quality smoothing, which keeps detail and avoids jagged edges.
- If you change nothing and keep the same format, your original file is downloaded exactly as it is, with no re-encoding.
- JPEG, PNG, and WebP images
- Max 20 MB
- Max 8000 px per side and 50 megapixels
- JPEG and WebP are lossy formats. Saving a new copy re-compresses the picture; use quality 100% or PNG for the least possible loss.
- A new file does not carry the original's camera details or GPS location (EXIF), which is also a privacy benefit.
- Enlarging beyond the original size cannot add detail.
- WebP output needs a browser that can save WebP; the tool tells you if yours cannot.
- Very large images are limited to protect your browser, and some phones allow smaller canvases than desktops.
This tool runs in local-only mode. Your text or files are processed in your browser and are not uploaded to our servers for this feature. Keep originals on your device; downloads create a separate copy.
- Will quality be lost?
- Not unless you ask for it. With no edits and the same format you get your original file back byte for byte. When you edit, the crop is taken from your original pixels, shrinking is done carefully, and you can pick PNG or 100% quality for the least loss.
- Can I crop to a specific shape?
- Yes. Choose Free, Original, or a ratio like 1:1, 4:3, 16:9 or 9:16. For exact numbers open Precise crop and type the left, top, width and height in pixels.
- Why does the file size change?
- Size depends on the pixels and the format. Fewer pixels make a smaller file; PNG is larger than JPEG for photos. Lower the quality for a smaller JPEG or WebP.
- Is my image uploaded?
- No. Everything happens in your browser, and nothing is sent to our servers.
