← backLevels, light, white balance, colour, text & a white border — one photo or a whole batch. Everything stays on your device — nothing is uploaded.
Histogram
Backgroundshow maskreset
A white point that only reaches the backdrop. Luminance decides what counts as background, so anything darker than the floor is left exactly as it was — show the mask to see where the line falls.
Lightreset
Colour balancereset
Each range keeps its own three sliders — a cast in the shadows can be pulled without touching the highlights.
Vignettereset
Positive darkens the edges, negative lifts them. It runs last, so a vignette falls cleanly across a backdrop already taken to white. To even out a backdrop that fades into the corners, ⌖ Pick background is the better tool — it already reaches the darkest part of it.
Crop & rotatereset angle
Straighten turns the photo up to 45° either way — the quarter turns above reach anything further. Fill frame scales the picture up until the corners are covered, so the size and shape stay put; whole frame keeps every pixel and leaves the corners clear — clear in a PNG or WebP, white in a JPG, which has no transparency to keep them in.
Textreset
Size and margin are shares of the long edge, so the words keep their proportions whatever size you export. Long lines wrap to the margins; Enter starts a new line yourself. Over a busy photograph Shadow lifts the letters off it and Panel lays them on a pad — both take their darkness from the colour of the type, so light words get a dark backing and dark words a light one.
Borderreset
A white margin laid around the finished picture, measured as a share of its long edge — so one setting frames a web-sized copy and a full-resolution one the same way. It goes on last and sits outside the photograph: nothing is cropped to make room, and the file grows by the border on all four sides.
