Image Cropper & Resizer

You can upload PNG, JPEG, WebP, GIF, and BMP images. The tool uses the browser Canvas API to process images, so any format your browser supports will work. You can export the result as PNG, JPEG (with adjustable quality), or WebP.

When exporting as JPEG or WebP, you can control the quality slider (1–100%). Lower quality means smaller file size but more compression artifacts. PNG export is always lossless and produces larger files.

There is no hard limit, but very large images (e.g., 50+ megapixels) may be slow to process since all work happens in your browser using the Canvas API. Typical photos process instantly.

When the aspect ratio lock is enabled, changing the width automatically adjusts the height proportionally (and vice versa) based on the original image dimensions. This prevents distortion.

No. All processing happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device — nothing is uploaded or stored anywhere.
