No account, no limits

Two tools. No compromises.

Oxel does two things and does them fast.

Background removal: before and after comparison showing a photo of Stanford arches with the background removed

Background Removal

Powered by RMBG 1.4, running as a Core ML model on your Mac. No uploads, no API calls.

✓ Product photos, portraits, objects — clean cutouts every time
✓ Outputs transparent PNG automatically
✓ Drop a folder → every image processed in batch
AI upscaling: before and after comparison showing a mosaic window image upscaled from 300x300 to 2400x2400

AI Upscale

AI-powered resolution increase via Core ML. Sharpen details, reduce artifacts, get print-ready results.

✓ 2x, 4x, and 8x upscaling — choose the level you need
★ Preserves transparency — upscale PNGs with alpha channels intact
✓ Drop a folder → upscale everything in batch

Drop. Process. Done.

No menus, no settings, no learning curve.

Drag and drop

Drop a single image or an entire folder onto Oxel. That's it — no file pickers, no import dialogs.

Oxel processes locally

The Neural Engine runs the AI models on your hardware. Background removal and upscaling happen in seconds, not minutes.

Processed images are saved to the output folder you choose. Originals are never modified.

Why Oxel

"Online tools upload my images to their servers."

Oxel runs entirely on your Mac. Your files never leave your machine. No uploads, no cloud processing, no third-party access to your work.

"Upscalers destroy my transparent backgrounds."

Oxel preserves alpha channels during upscaling. Drop a transparent PNG in, get a transparent PNG out — at 2x, 4x, or 8x the resolution.

"I have 200 product photos to process."

Drop the folder. Oxel batch-processes every image using the Neural Engine. Hardware acceleration means it finishes in a fraction of the time.

"I need it to work on a plane, at a cabin, wherever."

Oxel works fully offline. No internet connection needed, ever. The AI models are bundled in the app.

For Developers

Built on OxelKit

OxelKit is the shared framework that powers image processing in both Pexper and Oxel. It wraps Core ML models for background removal and upscaling into a clean, reusable API.
