What is Pix Fix?

Pix Fix offers a solution for enhancing images affected by noise and over-compression from JPEGs. It employs sophisticated proprietary algorithms to meticulously reconstruct images. The tool aims to eliminate as much noise as possible while carefully preserving essential image details. This process helps users restore the quality of their visuals.

Accessible entirely free of charge and without advertisements, Pix Fix operates directly within the user's web browser. This client-side processing ensures that images are never uploaded to a server, maintaining user privacy. The tool provides different modes, such as 'Graphics Mode' for rasterized vector art and scans, and 'Photo Mode' for photographs degraded by JPEG compression, along with adjustable smoothing levels for customized results.

Features

Noise Reduction: Effectively removes noise from images while retaining important details.
JPEG Artifact Removal: Cleans up images degraded by excessive JPEG compression.
Browser-Based Processing: All image processing is done in JavaScript within the user's browser, ensuring images never leave the computer.
Graphics Mode: Specialized mode for rasterized vector art or scans, removing JPEG blocking noise, scan artifacts, and other distortions while preserving edges and gradients.
Photo Mode: Optimized for photographs with excessive JPEG compression, using an extension of the anisotropic diffusion algorithm.
Adjustable Smoothing Level: Control the intensity of smoothing with a 1-10 scale for customized results.
Batch Processing: Allows users to pick multiple images (up to twenty) to process simultaneously.
Free to Use: Completely free with no advertisements.

Use Cases

Restoring old or low-quality photographs affected by noise.
Improving the visual quality of images heavily compressed for web use.
Cleaning up scanned documents or drawings with artifacts.
Enhancing rasterized vector art by removing distortions.
Preparing images for professional presentation by reducing imperfections.
Salvaging images with digital noise from various sources.

FAQs

Is Pix Fix free to use?

Absolutely! Pix Fix is completely free to use and there are no ads.
Are my images safe when using Pix Fix?

Definitely! All processing is done in JavaScript in your browser so your images never leave your computer.
What is Graphics Mode best for?

Graphics Mode is best suited for images that are rasterized vector art or scans of similarly styled drawings or prints. It gets rid of JPEG blocking noise, scan artifacts and other distortions, without leaving residual smudges. It also preserves edges, gradients and most narrow features.
How does Photo Mode work?

Photo Mode is best suited to photographs that have been degraded by excessive JPEG compression. The algorithm is an extension to the well-known anisotropic diffusion algorithm, enhanced to better handle JPEG blocking noise by boosting diffusion coefficients between pixel pairs that span a JPEG block boundary for images with high distortion scores.
What does the smoothing level control?

The smoothing level is a number between 1 and 10 that controls how much smoothing is done to your image. A level of 1 barely alters your image, while 10 does the most smoothing. The default level of 5 is intended to be a happy medium suitable for most images.
