Many photos in.
One sharp result out.

ForgePix turns a focus series into a clean, sharp macro photo — automatically, on your own computer, with no account.

Drop your photos in and press one button: it removes the bad shots, lines the rest up and builds one sharp image. Free and open source.

Also includes a full astro workflow — calibration, star colours, plate solving, photometry — plus Moon mosaics and long‑exposure effects.

What ForgePix does for you

It does the hard parts automatically

You take the photos — ForgePix turns them into one clean, sharp result. In plain words:

🔍

Makes everything sharp

Lots of photos that are each only sharp in places become one photo that’s sharp everywhere.

🗑️

Throws out bad shots

Shaky or useless photos are removed automatically — and it tells you why.

🔢

Tells you how many to take

A simple helper works out how many photos you actually need. No guessing.

💧

Silky water, no special gear

Turn a quick burst into smooth water or light trails — without an expensive filter.

🌌

Stars and close‑ups

Night‑sky shots and tiny‑detail shots — both in the same easy app.

🔒

Stays on your computer

Everything runs on your own machine. Nothing is uploaded. No account, no AI required.

How it works

From a blurry series to one sharp photo

Four simple steps — and you can see what happens at each one.

Your photos
1 · YOUR PHOTOS

Drop them in

A few shots, each sharp only in places.

Auto check
2 · AUTO‑CHECK

Cleans up

Bad photos removed, the rest lined up.

Combine
3 · COMBINE

Picks the best bits

Takes the sharp part from each photo.

4 · DONE

One clean photo

Sharp everywhere, ready to use.

Four tools in one app

Pick what you want to do

Choose when you open the app — switch any time.

🔬

Close‑ups

Razor‑sharp photos of small things — products, coins, food, jewellery, insects. ForgePix combines your shots so the whole subject is in focus.

🌌

Night sky

Combine many star photos into one clean night‑sky image with less noise. Darks and flats are applied, photos spoiled by clouds or a passing satellite are dropped, and you get a report on what to improve next time.

🌗

Moon & panoramas

Stitch several shots of the Moon or Sun into one big, detailed picture — or combine frames for extra clarity.

📷

Long exposure

Silky water, soft clouds or light trails — made from a normal burst of photos. No tripod tricks, no special filter needed.

For astrophotographers

The astro toolkit

From raw FITS files to a measured, calibrated result — on your own computer, without Siril or PixInsight installed.

🧪

Calibration done right

Darks, flats and bias frames. A master dark taken at a different temperature or exposure time is rescaled to match, and a superbias removes read noise from the bias.

🧭

Knows where it points

Plate solving runs on your computer — no internet, no external solver — for image fields from about one arcminute to five degrees across.

🎨

Star colours from real stars

Colours are calibrated against the known colours of catalogue stars (Gaia), instead of simply making the average star white. The catalogue for your sky region is downloaded once, then it works offline.

📋

Checks before it stacks

Spots mixed cameras, gains, exposure times or sky fields in one folder before hours of work. After stacking you get a measurement report with concrete advice.

📈

Measures, not just pretty

Aperture photometry for variable stars: light curves and a report file in AAVSO format.

☄️

Live, comets and more

Live stacking while you capture, comet stacking with Larson–Sekanina for jets, drizzle for clearly undersampled images, and PixelMath with star and background masks.

Beta: much of this is new. Every step reports what it measured — if a result looks off, please tell us on GitHub.

A look inside

Made for everyone, not just experts

Clear buttons, a help “?” on every option, a simple Beginner mode, and a photo editor built right in. Click any picture to see it full size.

Start screen — pick a module.
Macro — one sharp result.
Astro — deep‑sky stacking.
Built‑in editor — exposure, colour, curve, crop.

Real results

Made with ForgePix

Actual photos stacked in ForgePix — straight from the app.

Macro focus stack
Macro — flies in amber, fully sharp.
Cocoon Nebula
Astro — Cocoon Nebula (IC 5146).
Orion Nebula
Astro — Orion Nebula (M 42).

Astro: from trailed stars to round stars

Stars before alignment
Before — frames not aligned: stars smeared and doubled.
→
Stars after alignment
After — auto‑aligned: clean, round stars.

One capture, every palette

Switch the colour palette (HOO, SHO …) with one click — without re‑stacking.

What you get

Everything’s included

  • One‑button automatic — or a Pro mode with full control.
  • Opens your camera’s photos, including RAW files — colours stay true.
  • Built‑in photo editor — brightness, colour, crop, and more.
  • Fix‑up brush for the few tricky spots.
  • Before/after slider so you can see the difference.
  • Ready‑made export for Instagram, WhatsApp, web, 4K or printing.
  • Whole folders at once, and a watch mode for new photos.
  • English & German, and you can do everything with the keyboard.

Runs on its own

ForgePix works completely offline. No account, no sign‑up, no internet, no AI needed — your photos never leave your computer.

ForgePix comes with four small AI models of its own — for noise, background, deblurring and star removal. They run locally, are still experimental and are switched off unless you turn them on. Everything else is classic, measurable image processing.

“The app explains why it made each choice.”
