Image editor: frequently asked questions

No. Your browser decodes and edits the image in memory on your device. The editor makes no network request while you work, and our automated tests fail the build if any source file gains a fetch, an XHR, a WebSocket or a beacon call.

Yes, once the page has loaded. There is nothing for it to contact.

No. Closing or refreshing the tab discards the document and the undo history. Storing your image would mean keeping a copy somewhere, which is precisely what this tool avoids. Export anything you want to keep.

Because it exceeded the pixel budget for your device. A browser canvas has a hard ceiling — around 16.7 million pixels on iOS — and exceeding it produces a blank canvas or a killed tab rather than an error you can recover from. The editor scales the image to fit and tells you the dimensions it used.

Yes. The editor uses unified pointer events, so a finger or stylus behaves exactly like a mouse, and the canvas claims its own gestures so drawing does not scroll the page. The page still scrolls normally outside the canvas.

Deliberately limited. You can add, select, reorder, hide, set opacity, merge down and flatten, up to twelve layers. There are no blend modes, masks, groups or adjustment layers. We would rather ship a small layer system that works reliably than a large one that half works.

History is capped by both step count and total memory, because each step retains a copy of the pixels it changed — tens of megabytes each on a large image. The oldest steps are discarded first. The status line shows how much is currently retained.

PNG, JPEG and WebP, both ways. RAW, HEIC, TIFF, GIF and SVG are not supported. PNG and WebP keep transparency; JPEG does not, and the editor warns you before flattening it to white.

Partly scope, and partly that the obvious set of filter names belongs to another company. Any effects we add will have plain descriptive names such as Warm, Cool, Fade, Mono or Vignette.

Yes, if you do it properly: draw a solid filled shape over the area, flatten the image, then export and check the result. Do not rely on reduced opacity or a hidden layer, because the original pixels survive both.

There is no account system anywhere on ToolAcre, so there is nothing to sign up for and nothing to delete. A cloud save would require uploading your image, which would make the privacy claim on this page false.
