Powered by Ghostscript WASM: This tool performs true industry-standard PDF distillation entirely within your browser. It resamples images and optimizes streams while perfectly preserving text highlightability and vector paths.

No Artificial Upload Limits

Files are processed directly on your device rather than being uploaded to external servers.

Because processing happens locally, performance depends on your device's available memory, processor speed, browser capabilities, and file complexity. Large files may take longer to process on older or lower-powered devices.

UtilityLab does not impose artificial upload restrictions, but practical limits are determined by the capabilities of your device.
