Photos never leave your browser. Best results come from a stationary scene with consistent framing.
01 / COMBINE
Merge settings
Prefer a sharp image with minimal moving objects.
Favors the reference when differences suggest moving subjects. Not guaranteed ghost removal.
Large photos are resized to a stack-aware memory budget; original files are untouched.
Actual working resolution adjusts with stack size and available memory.

Your merged image appears here
Load at least two exposures, then select Merge exposures.
Tip: for the cleanest merge, use bracketed shots from a tripod.
HOW IT WORKS
Natural detail, less effort
Exposure fusion combines useful information from differently exposed photographs into one display-ready image.
Align and blend
Correct small translations, emphasize well-exposed pixels and blend details across scales to reduce visible seams.
Shape the final look
Fine-tune highlights, shadows, contrast and color, compare against your reference and export a shareable image.
Frequently asked questions
Does this export a true HDR file?
No. This studio performs exposure fusion to create a standard-dynamic-range image that resembles HDR photography. PNG, JPEG and WebP downloads are 8-bit-per-channel display-ready files, not Radiance .hdr, EXR or HDR gain-map exports.
Can it fix moving people, leaves or cars?
Motion protection can reduce some ghosting by favoring the reference frame. It cannot reconstruct every moving subject, repair large camera movement or replace dedicated optical-flow alignment.
Does it read exposure values or retain original resolution?
No. The current exposure-fusion method does not require EXIF shutter times. Uploaded files are decoded and downsampled to a stack-aware processing budget of up to 4 megapixels, and EXIF metadata is not retained in the export.
Are my images uploaded?
No. The entire image decoding, blending and export workflow runs locally in your browser. The tool does not transmit your photos to PixelOkay or a third party.
Which browsers work?
Modern browsers with Canvas, Web Workers and image decoding APIs. JPEG and PNG are broadly supported; WebP availability depends on the browser. Large jobs may fail on low-memory devices—try the 1 MP preset if so.
