YOUR FILES
Look first. Convert when you are sure.
Every card shows the JPEG your camera embedded. Click one to open the viewer. Convert when the settings are right.
Reads the sensor data and renders it fresh at full size. Best quality, a few seconds a file.
METADATA
Click any frame to open the viewer: 100% zoom, histogram, camera settings, and exposure, white balance and contrast sliders. Everything clears when you close the tab.
HOW IT WORKS
A real RAW developer,
running on your machine.
Not a thumbnail puller dressed up as a converter. The same decoding library behind desktop RAW tools, compiled to run in your browser.
01
It shows you what the camera already made
Every RAW holds a JPEG your camera wrote at capture. The tool finds it in the file and shows it in under a second, so a card of 40 frames is browsable before you have finished reading this sentence.
02
It develops the real thing when you ask
Full develop reads the sensor data with LibRaw: demosaic, camera white balance, color matrix, full size. A neutral, honest render with room to push exposure. Two to ten seconds a file depending on megapixels.
03
It never leaves your machine
The decoder is WebAssembly running in your browser. Files go from your disk into memory and back out as JPGs. No server touches them, which is also why it keeps working with the wifi off.
04
It writes a JPG that still tells its story
Camera, lens, shutter, aperture, ISO and capture date go into the JPG so Lightroom and your gallery still read them. GPS is never copied. Untick one box for a file with no metadata at all.

Speed depends on megapixels and your machine. The camera preview of a 24 megapixel file shows in well under a second; a full develop takes a few seconds on a recent laptop. A phone works, a laptop is more comfortable.
FORMATS
Every brand.
Twenty six extensions.
Decoding follows LibRaw releases. If a brand new body is not read yet, the camera preview still works because it does not depend on the sensor format.

COMMON QUESTIONS
Before you drop a card.
Something we missed?
A body that does not read, a file that renders wrong: send it over and we will look at the actual file. Contact →
Are my RAW files uploaded?
No. The converter runs entirely inside your browser. Files never leave your device, Kepla never sees them, and nothing persists after you close the tab. Turn the wifi off after the page loads and it keeps working.
How does the develop compare to Lightroom?
It is an honest, neutral render with the camera white balance and color matrix applied, close to a RAW editor at default settings before any profile or preset. It is not an edit. It is the fastest way to a clean full size JPG without installing anything.
Why does the camera preview look different from the develop?
The preview carries your camera's picture style, sharpening and contrast. The develop is deliberately neutral. If it looks flat or a touch dark, that is the sensor data speaking. Use the sliders in the viewer.
What does "Keep camera info" do?
Writes camera, lens, exposure settings and capture date into the JPG so the file still tells its story. GPS is never copied. Untick it for a JPG with no metadata at all.
Is there a size or batch limit?
Up to 40 files a batch. The work happens in your browser's memory, so very large files from 60 megapixel and up bodies convert one at a time and take a few seconds each.
Can it open HEIC, or edit the JPG afterwards?
HEIC is not RAW and browsers cannot decode it here yet; export to JPEG from Photos first. For resizing and cropping the JPGs you just made, the image resizer is next door.
