Tool Guide

Retouch and Mosaic Tool Guide and FAQ

Use the retouch and mosaic workspace to paint over local image areas. Lightweight repair can clean small blemishes, while mosaic masking helps hide faces, license plates, QR codes, private text, and other sensitive regions before sharing.

When sharing images publicly, you sometimes need to obscure sensitive information — a face in a crowd photo, a license plate in a car picture, a phone number on a document, or a credit card in a receipt. TUXIA's Retouch and Mosaic Tool provides two modes for local image editing: lightweight repair (for small blemishes or minor distractions, using pixel blending to smooth over the painted area) and mosaic masking (for privacy, applying a pixelation grid to obscure details). You paint the target area with an adjustable brush, choose the mode, and apply the effect. The result downloads as a new image with the edits baked in. All processing happens locally on the Canvas, so sensitive images never leave your device.

Common Use Cases

Privacy Protection Before Sharing

Blur or pixelate faces, license plates, house numbers, email addresses, phone numbers, and other personal details from screenshots, photos, or document scans before posting them online or sending them to others.

Minor Blemish Cleanup

Remove small dust spots, skin blemishes, stray hairs, or minor sensor spots from photos using the lightweight repair mode. Best for small, isolated imperfections rather than large-area edits.

Sensitive Document Redaction

Apply mosaic masking over confidential text, account numbers, signatures, or QR code fragments in document photos before sharing them for reference or support purposes.

How It Compares

TUXIA's retouch tool provides basic local editing in the browser without any uploads. It excels at privacy masking and small blemish fixes. For professional retouching — AI-powered object removal, content-aware fill, skin smoothing, or complex compositing — dedicated tools like Photoshop, GIMP, or online AI editors offer much more advanced capabilities. TUXIA's advantage is privacy and simplicity: no account, no upload, instant results for common privacy tasks.

Technical Notes

  • The retouch mode applies pixel-level blending — it samples surrounding pixels and attempts to create a smooth transition over the painted area. Results depend on the image content and brush size.
  • Mosaic strength controls the size of the pixelation blocks. Higher strength means larger blocks and stronger obfuscation.
  • This is NOT AI-powered inpainting. The tool uses simple Canvas pixel manipulation. For complex object removal or large-area reconstruction, consider dedicated tools with AI capabilities.
  • The maximum supported image size is 10 MB to ensure smooth brush interaction and processing.

Best Practices

  • For mosaic masking, use a brush size that comfortably covers the target area in a few strokes. The mosaic effect is applied once you click the apply button.
  • For retouch mode, keep brush size close to the blemish size. Large brush strokes create unnatural-looking blended areas.
  • Always preview the result at full size before downloading. Mosaic masking may leave edges visible if the brush does not fully cover the target.
  • Only process images you have rights to use. Respect others' privacy when applying masks to photos that include people who have not consented to sharing.

Best for

  • Mask private areas with mosaic blocks.
  • Apply lightweight local repair to small visual distractions.
  • Export a privacy-safe copy without uploading the image.

How to use it

  1. Upload an image and choose retouch or mosaic mode.
  2. Adjust brush size and strength, then paint the target area.
  3. Preview the result and download the edited image.

Frequently asked questions

Is the retouch feature the same as AI inpainting?

No. This static browser tool provides lightweight local repair, not cloud AI inpainting.

When should I use mosaic mode?

Use mosaic mode when you want to hide sensitive details such as faces, IDs, license plates, QR codes, or private messages.

Can I undo edits?

You can clear the selection or reset the image before exporting the final result.
