About

Erasa

Erasa is the honest object eraser. Brush over what you want gone โ€” power lines, date stamps, watermarks, photobombers โ€” and Erasa fills it in, right on your phone. โ€ข ON YOUR DEVICE. Every photo is processed right on your iPhone using on-device machine learning. Your photos are never uploaded โ€” the erasing even works in airplane mode. โ€ข NEVER RESIZED, NO WATERMARK. Your photo is never resized โ€” edits save at the original resolution. No "pay to unlock your photo," no stamp across your image. โ€ข FREE โ€” HONESTLY. Erase as much as you want for free, supported by a single banner ad. No subscription, no free-trial trap, no surprise paywall after you edit. Prefer no ads at all? A one-time $7.99 "Go ad-free" removes them for good โ€” yours forever, no subscription. HOW IT WORKS 1. Pick a photo. 2. Brush or lasso over the thing you want to remove โ€” cover the whole object, a little past its edges. 3. Tap Erase. Compare before/after, undo if you like, then save. Tip: for big objects, erase in a few smaller passes for the cleanest result. Erasa keeps it simple and fair: powerful on-device erasing, your photos stay yours, and a price model that respects you.
