Docs
Remove noise from your images with three professional-grade filters: bilateral (edge-preserving), median (salt-and-pepper), and Gaussian blur. All processing runs locally in your browser.
Key Features
- Three denoising modes: Bilateral filter, Median filter, Gaussian blur
- Adjustable strength (light / medium / strong)
- Configurable kernel size (3x3, 5x5, 7x7)
- Output in PNG, JPEG, or WebP format with tunable quality
- Drag & drop, click to browse, or Ctrl+V paste — flexible upload
- Before/after tab switching for instant comparison
- All processing runs locally — no data ever leaves your browser
How to Use
- Upload an image by dragging it into the canvas, clicking “Browse”, or pasting from clipboard
- Select a denoise mode: Bilateral (preserves edges), Median (removes specks), or Gaussian (smoothing)
- Adjust strength and kernel size as needed
- Click Denoise to process
- Switch between Before/After tabs to compare
- Choose output format and quality, then click Download
Common Use Cases
- Cleaning up scanned photos and documents with dust, grain, or JPEG artifacts
- Reducing sensor noise in low-light photography
- Pre-processing images before further editing or compression
- Removing speckle noise from flatbed scans
- Smoothing AI-generated images with subtle artifacts
Notes
- For best results, use Bilateral for general noise (it preserves sharp edges)
- Use Median for salt-and-pepper / speckle noise (dust on scans)
- Use Gaussian for subtle smoothing before compression
- Images are resized to max 1200px for performance

FAQ
Is it free?
Yes, 100% free. No signup. All local.
Which denoise modes?
Bilateral, median, and Gaussian filter.
Is my image uploaded?
No. Everything stays in your browser.
Is this tool suitable for ecommerce, social media, or email images?
Yes. Ecommerce images usually need clean edges and consistent sizing, social images need stronger cropping and visual impact, and email images need smaller file sizes. Export different sizes for each target channel.
Are my images uploaded to a server?
Most image tools on the site prioritize local browser-side processing, which is better for privacy-sensitive assets. If any AI feature has a usage cap or depends on a cloud model, the page copy will call that out explicitly.
How do I choose between PNG, JPG, and WebP?
Choose PNG for transparent backgrounds, JPG for photos and heavier compression, and WebP when you want a better balance of quality and file size. If your target platform requires a specific format, follow that first.
Do I need to sign up, download, or install anything?
Most Gotokit tools are designed to open directly in the browser without a separate install. If a tool has a quota, browser requirement, or third-party dependency, the page copy will state that clearly.
Can I use this tool on mobile phones or tablets?
Most tools work in modern mobile browsers, but complex charts, larger files, and precision drag-and-drop tasks usually feel better on desktop. If speed and control matter, desktop is the safer choice.
