Resize & Edit

Tools for resizing, cropping, rotating, watermarking and blurring images.

Six small editors for the fixes that shouldn't require installing anything. Image Resizer scales a picture to exact pixel dimensions — the usual reason a form rejects an otherwise fine photo. Crop Image cuts to a region or aspect ratio. Rotate Image and Flip Image fix orientation from cameras and scanners. Add Watermark to Image stamps your name or logo across work you're about to send — useful for freelancers and photographers sharing drafts they don't want reused unpaid. Blur Part of Image hides what shouldn't be shared: a face, an address, an account number on a screenshot, before it goes into a chat or a public post.

The privacy point is not decoration here. The images people edit are precisely the sensitive ones — IDs, forms, screenshots of private conversations, photos of children. Every tool on this page runs on the Canvas API inside your own browser: the image is opened, edited and saved on your device, and never crosses the network. A blurred document was never visible to anyone but you, because the unblurred original never left your machine.

No watermarks except the ones you add, no sign-up, no limits. For hitting an exact file size after editing, hand the result to the compress tools.

Frequently asked questions

How do I resize an image to specific pixel dimensions for an upload form?

Open Image Resizer, type the exact width and height the form specifies, and download. If the form also enforces a file-size limit in KB, run the resized image through the Image Compressor's Target Size mode afterwards.

Is it safe to blur sensitive information in a document online?

With Blur Part of Image, yes — the editing happens entirely in your browser, so the unblurred original never touches a server. Drag over each region you want hidden and adjust the strength until the detail is unreadable before downloading.

How can I watermark my photos before sending them to a client?

Use Add Watermark to Image to place your name or logo across the picture. It's a standard way for freelancers and photographers to share preview versions while making unauthorised reuse impractical.

Why do my phone photos appear sideways when uploaded?

Phones record orientation as metadata that some websites ignore, so the image displays rotated. Run the photo through Rotate Image to bake the correct orientation into the pixels themselves — it will then display upright everywhere.
