Image Overlays

This subcategory offers 6 free tools that need no account and dress up an image in your browser. It is useful to protect a creation, frame a visual, prepare an avatar, place a color behind a transparent logo or change a targeted shade. Tools include Add watermark, Add a border, Round the corners, Color overlay, Add background and Replace a color. Files stay in your browser when the tool page says so.

Start with the final dressing. Add watermark places a discreet text, Add a border adds a colored frame and Round the corners exports a PNG with rounded corners. Color overlay applies a color with opacity, Add background places a color behind a transparent image. Replace a color targets a shade with tolerance. If you mainly need to protect an image, begin with watermark. For a card or thumbnail look, try border then rounded corners.

How to use

  1. Choose the final overlay: Add watermark to protect, Add a border to frame, Round the corners for an avatar or card.
  2. For a global color, use Color overlay with moderate opacity, then check that text or subject remains readable.
  3. If the image is transparent, place a color behind it with Add background before exporting as PNG to keep transparency.
  4. To target one shade, use Replace a color with tolerance, testing several settings before applying the final result.

Frequently asked questions

How do I protect an image with a watermark?

Use Add watermark to place a discreet text over the image. You choose the content and placement before export. The file stays in your browser and no account is required. For a frame, complete it with Add a border.

How can I change a dominant color in an image?

Replace a color acts on a target color with tolerance. Color overlay applies a color with adjustable opacity. Depending on your need, pick a precise target or a global wash. Test several settings before exporting.

How do I prepare a visual with rounded corners and a border?

Add a border first with Add a border, then round the angles with Round the corners. Export as PNG to keep the corners clean. If the background must be transparent, complete it with Add background or Color overlay depending on the look you want.
