Draw on the image. Keyboard: arrows move the cursor, Shift moves 10 pixels, Enter/Space paints. Escape, pointer cancellation or losing focus rolls back a stroke.

Settings

MODNet portrait uses a square 256×256 sample for one person; it is not a general-object model. Original aspect ratio is restored for PNG. Weights are about 26 MB. Texture allocation payload is capped at 128 MiB, not physical browser memory. Erase/restore works at original dimensions; at most six undo masks, a 1–256px brush and 45-second processing checkpoints. Unsupported GPUs fail explicitly; manual mask does not run a model.

Current outputPNG

MODNet is for a single portrait, not general objects. Hair, glass and similar backgrounds may need manual refinement. PNG keeps original transparency.

Images stay on this device. Selecting an image starts processing and loads model assets from this site.

Generate a portrait mask locally, check its edges, and refine before exporting.

How to remove a background

  1. Choose one static JPEG, PNG or WebP within 15 MB, 4 million pixels and 4096 pixels per side.
  2. Background removal starts after image validation. You can cancel and use a manual mask, then erase and restore using the image or exact coordinates.
  3. Review the exported result. Mask edits automatically update the transparent PNG; download when ready.

Mask editing and local limits

Output keeps the oriented original dimensions and original alpha; the file is re-encoded as PNG. The model’s 256-pixel prediction does not recover missing fine detail. No JPEG flattening or remote processing is used.

The brush diameter is 1–256 original-image pixels. Choose Erase or Restore, draw, or enter X/Y integer coordinates. Keyboard arrows move the editing cursor; Shift moves ten pixels and Enter/Space paints. Escape, pointer cancellation or blur rolls back the current stroke. Undo/redo retains at most six masks; resetting restores the initial model or manual mask.

Processing uses 45-second checkpoints and a task-owned WebGL2 runtime. Cancellation, clearing, replacing the input and leaving invalidate late callbacks, release GPU/image resources and remove downloads. GPU capacity varies by browser/device. Unsupported models fail explicitly; manual editing remains available. Files, masks and settings are not saved or sent to analytics.

Common questions

Are images sent to a server?

No. The fixed model and runtime load from this site after image selection and validation; image pixels stay in this page. File references can continue to another same-language image tool, but masks, history and download results remain local to this tool.

Can it perfectly remove hair, glass or shadows?

No. The compact MODNet portrait model predicts a 256×256 portrait mask, resampled to the original image. Fine hair, fur, glass, shadows, similar colors and complex subjects may leave rough edges or unwanted background. Use erase and restore, then inspect the downloaded PNG.

What if my GPU is unsupported?

The tool reports a model/GPU error rather than exporting a guessed result. You may explicitly start a manual mask without downloading the model, erase background areas and export PNG. Restore brings back original pixels and original transparency.
