OpenPixels review
A free open-source browser tool for batch upscaling, restoration, and offline processing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenPixels is a free, open-source web application for enlarging and restoring photographs locally in the browser. It supports AI upscaling at 2×, 4×, and 8×, with JPEG, PNG, and WebP input formats. The feature set also covers noise and JPEG-artifact removal, face restoration, black-and-white photo colourisation, and background removal with transparent PNG output. It suits individuals, photographers, and teams that want browser-based image processing without an account, watermark, paid tier, or usage limit.
Pricing is straightforward: the Free plan costs nothing and includes 2×, 4×, and 8× enlargement, batch processing, no account requirement, no watermark, and unlimited photo processing. There are no paid tiers to compare, so the full listed feature set is available without a subscription decision. For repeated image work, batch processing can produce ZIP results, while CSV quality measurements provide a structured output for batch runs. This makes OpenPixels a practical fit for users who need to process multiple photographs rather than enlarge images one at a time.
Its browser and local-processing model shape the overall fit. Photos are processed on the user’s device and are not uploaded, and the application can operate offline after its models are cached. That combination suits users who want a web-based workflow with local operation. OpenPixels also goes beyond enlargement with restoration, colourisation, face processing, and transparent-background output. Users who require a native application or a platform other than the web should choose another tool; for browser-based batch upscaling with no recurring cost, OpenPixels is the clear fit.
