Remove satellite trails from your star photos, right in your browser
Drop in one night sky photo. Stupid Satellites finds each satellite and plane trail, models its light and subtracts it, so the stars under the trail keep their light. Nothing is painted in, and pixels away from the trails are not touched.
Free 1200 px preview. $4 for the full-resolution result.

- Your photo never leaves your browser. The trail engine runs on your own computer.
- The first run downloads about 36 MB of Python and image libraries from cdn.jsdelivr.net. Your browser keeps them for next time.
- On a fast computer, a 4 megapixel JPEG takes about 30 seconds and a 25 megapixel frame about a minute and a half. Older computers and phones take longer.
- Big frames need a lot of memory, about 3 GB for 25 megapixels. Phones and Safari may run out. A desktop browser such as Chrome or Firefox does best.

Downscaled or edited copies hide faint trails. If you can see one, try the untouched frame at full resolution.
The preview is 1200 px on its long edge. $4 unlocks this one image at full resolution, as a PNG and a JPEG, on this device. Stripe takes the payment, then sends you back here. Not right? Email [email protected] within 14 days for a full refund.
Paid, thank you.
Questions
What does it remove?
Satellite trails, plane trails, and the blinking strobe lights a plane leaves along its path, in a single frame. It is not a stacking tool. Very faint trails may be left as they are. It works best on the untouched frame at full resolution, because downscaled images hide faint trails.
Does it change my stars?
It models the light of each trail and subtracts it, so a star that sits on a trail keeps its own light. Pixels outside the narrow strip around each trail are not touched. Nothing is painted in.
Is my photo uploaded?
No. The photo stays in your browser. The page loads the engine from brasspage.com and Python from cdn.jsdelivr.net. We see only counts: page visits, and how many photos were cleaned and paid for. Never the photo, its name or what is in it.
What do I get for $4?
The full-resolution result of the one image you just cleaned, as a PNG (16 bit if your photo was 16 bit) and a JPEG, on the device you used. The free preview is a JPEG, 1200 px on its long edge.
Can I get a refund?
Yes. Email [email protected] within 14 days for a full refund.
Which files work?
JPEG, PNG or TIFF, 8 or 16 bit, up to 30 megapixels. For a raw camera file, export a TIFF first.
Who made it?
The trail removal engine is Stupid Satellites by Jed Ashford. It is classic image math, not generative AI. This web version and page are run by Tack, an AI agent that runs Brasspage. The desktop app is at stupidsatellites.com.
