How it works
The Watermark Cleaner is a browser-based inpainting tool that helps you remove small watermarks, logos, or text overlays from images you own or have rights to edit — using canvas-based fill interpolation to replace the selected region with surrounding texture and colour.
Important: this tool is designed for legitimate use cases — removing your own older watermark when rebranding, cleaning up stock photos you've licensed, or removing metadata overlays from screenshots of your own content. Do not use this tool to remove watermarks from images you do not own or have not licensed.
How the removal works: The tool uses a simple inpainting algorithm: you paint over the watermark area with a brush, and the tool samples the average colour and texture of the pixels immediately surrounding the selected region, blending them inward to fill the gap. This works best when the watermark sits over a uniform or gradient background. It does not work well on complex textures or when the watermark covers a detailed pattern area.
How to use: 1. Upload your image (JPEG, PNG, or WebP). 2. Select the brush size — small for precise text overlays, large for logo blocks. 3. Paint over the watermark area in the canvas view. 4. Click "Apply Inpaint" — the region is filled with surrounding colour samples. 5. Undo and repaint if needed (Ctrl+Z supported). 6. Download the cleaned image as PNG.
Best results: images where the watermark is over a sky, plain background, or solid colour. Worst results: watermarks over faces, detailed patterns, or areas with strong directional gradients.
Privacy: all image processing runs in the browser. Your image is never uploaded.
Frequently Asked Questions
- The inpainting algorithm works best on watermarks that sit over uniform or gradient backgrounds — sky, solid colour walls, plain fabric textures, and clean gradient backgrounds. Small text watermarks (date stamps, copyright notices) are removed cleanly when the surrounding area has consistent texture. The tool works poorly on watermarks over human faces, detailed patterns (brick, fabric weaves, foliage), or where the watermark is larger than 15% of the image area.
- Yes, for legitimate use cases — such as removing the TikTok watermark from your own videos when repurposing content to Instagram Reels (TikTok-watermarked content is actively suppressed by Instagram's algorithm). For still frames: upload the frame as an image, paint over the watermark area, and download. For video content, you'll need a video editing tool — this browser tool processes static images only.
- The browser-based canvas API can process images up to approximately 16,384×16,384 pixels. For practical use, images up to 8,000×6,000px (approximately 48 megapixels) work reliably across modern devices. Very large files (50MB+ RAW exports) may cause performance issues on lower-powered devices — consider resizing to 3000×2000px before uploading if you experience slow rendering.
- The inpainting algorithm used here is a patch-based fill: it samples the pixel colours and brightness values in a border zone around the painted area, calculates a weighted average of the surrounding pixels (weighted by distance — closer pixels have more influence), and fills the selected region with this blended colour. This simple approach works well for smooth backgrounds. It doesn't use AI or deep learning — it cannot reconstruct detail that exists behind a large watermark on a complex background.
