Planalta

Four corners.
Ready to deliver.

Turn a photograph of a flat artwork, poster or print into a rectangular image. Place its corners, enter the known original proportions and generate multiple delivery sizes locally.

From a photograph to files

Import from Photos or Files. Four numbered handles move clockwise from top left; the pixel loupe and one-pixel nudge arrows help you align the edges. Choose a ratio or enter width and height in the same unit. iPhone switches corner/result views; iPad keeps source and corrected result side by side.

Choose up to five PNG/JPEG outputs, then Create delivery files. Share the real files and a JSON settings record through the native share sheet. Named projects keep the working source, corners, ratio and sizes. Reopen, rename, duplicate and delete them. Editing invalidates the current delivery list; regenerate matching outputs.

Scope and limits

Still images iOS can decode, up to 60 MB / 80 megapixels. The working copy is oriented and capped at 4096 pixels on the longest edge. Outputs are 320–4096 pixels on the longest edge; larger sizes may upscale the selected area. PNG is lossless; JPEG uses 95% quality. Original metadata is not copied into outputs.

A known original ratio restores intended proportions. Estimating from the photographed edges can stretch an image and does not determine physical dimensions. Flat subjects only; no lens correction, curved-page flattening, OCR, hidden-detail recovery or color calibration. JSON records settings, not a source-image backup.

Support

Email maga40@naver.com with app version, device, source dimensions/format and a description of the issue. Keep sensitive artwork or personal images out of email unless you intentionally choose to send them. For geometry questions include the original width-to-height ratio and output size.

Privacy policy

Effective October 1, 2026. Gobling Company provides Planalta. The app has no account, analytics, advertising, tracking or third-party data SDK. It does not collect or transmit your images, project names, coordinates, settings or exports to a developer server. Processing and project storage are local.

Only images you select through Photos or Files are read. The oriented working image, project name, corners, ratio, output sizes and generated delivery files are stored in the app. The library starts empty; a labeled original geometry example is created only on request.

Sharing sends selected image files and/or the JSON settings record to a destination you choose. The record includes the source filename and settings. Review it before sharing. Destinations have their own privacy practices.

Deleting an artwork removes its local working source and delivery files. Uninstalling removes app-local data. Previously shared copies remain at their destinations and must be deleted there. Device backups may include local data according to your Apple or computer settings. Save your outputs separately before deleting projects or uninstalling.

Support receives information you elect to email. Visiting this website makes ordinary web requests to its hosting provider. Neither is required to rectify or export an image.
