Get the iPhone photo editing tools on a Windows PC

If you edit on an iPhone and then sit down at a Windows PC, the tools change completely. Windows Photos has its own set, Google Photos on the web has another, and neither matches what your hands already know. Raspy recreates the iPhone's Adjust and Crop tools in the browser, so the same sliders, in the same order, with the same behaviour, are available on any computer.

What is the same

• The fifteen adjustments: Exposure, Brilliance, Highlights, Shadows, Contrast, Brightness, Black point, Saturation, Vibrancy, Warmth, Tint, Sharpness, Definition, Noise reduction and Vignette, in that order.
• The directions. Positive Highlights darkens, the way it does on the phone. Vibrancy protects skin tones. Straighten fills the frame as it rotates.
• The dial. Each adjustment is a ruler you drag, with a tick every step, rather than a thin slider you aim at.
• Compare. Press and hold the photo to see the original, exactly as on the phone. On a keyboard, hold Space.
• Crop with the same aspect ratio choices, rotate, straighten and flip, and undo and redo.
• HEIC opens directly. No conversion first.

What is different

Raspy is an independent open-source project, not an Apple product, and it stops at the Adjust and Crop tools. The iPhone's Filters tab, Portrait lighting, Markup, Live Photo controls and the newer AI clean-up tools are not there. It also runs on a photo you open, not on a library, so there is no syncing and nothing is kept between sessions. Each edit is a fresh open and a save.

Using it on a PC

1. Move the photos over. iCloud for Windows keeps a folder in sync; a USB cable or a cloud drive works too. Leave them as HEIC.
2. Open Raspy in Chrome, Edge or Firefox. Drop a photo anywhere on the page, or click Open photo.
3. Edit. The ruler responds to a mouse drag, a trackpad scroll, and to the arrow keys once it has focus. Double-click a ruler to reset it.
4. Save as JPEG. It goes to the Downloads folder; drag it back to wherever your photos live.

On a Mac

A Mac already has the same editor inside its Photos app, which is the right tool if the photo is in your library. Raspy is useful on a Mac for a photo that is not in the library and should not be imported into it, such as a file someone sent, and for editing in a browser that has no access to your photo collection at all.
