What “rebuilding the background” actually means

Deleting text from a JPEG is a hole-filling problem. The characters already overwrote the background. There is no hidden layer to switch off. “Removing” the letters means synthesising a plausible plate for that hole and pasting it back only where the mask says so.

A white brush, a blur, or a soft clone is not a rebuild. Those hide the word under a smear. A specialised text erase aims for something stricter: the grain, lighting, and colour of the surroundings continue through the hole, and you should not still read a ghost of the letter in the texture.

Why FX ride along

Lettering rarely sits alone. Glow, stroke, drop shadow, reflection, residual traces, and warped type all sit slightly outside the hard glyph. If the rebuild only fills the black of the letter, you get a clean hole with a soft halo still glued to it. EraseText is built so those effects leave with the type — the surface reads as one piece, not a caption-shaped patch.

What the mask is for

The mask tells the model which text to clear. It does not need to be a pixel-perfect outline. A box that runs a little wide or a little tight still removes the lettering, including glow and shadow that sit slightly outside. That forgiveness is intentional: you pick *which* writing goes, not every glyph edge by hand.

• All text — detect every word, wipe the frame, then restore-brush original pixels back where erase went too far.
• Select text — erase the boxes you tick, or keep selected strings and erase the rest.
• Brush erase — paint a region for a stamp or mark OCR missed.

What good looks like at 100%

• No ghosting — you cannot still read the word in the grain.
• Neighbours stay put — logos, faces, and second lines outside the mask are unchanged.
• FX gone with the type — no leftover stroke or shadow shaped like the old caption.
• Match to surroundings — lighting and colour of the patch continue from the plate around it.

Wall-clock is a few seconds on the web; the erase pass itself is typically about a second. Free to try. Same specialised erase in the editor and over the API.

Upload a frame with readable type, run All text or Select text, then Compare at 100%. You are looking for a continuous plate — not a painted-over word. That continuity is what “rebuilding the background” is supposed to mean.
