Frequently Asked Questions

Are my images uploaded to your servers?

No. Unlike typical online compressors that upload your private pictures to external cloud servers, PromptGallery Smart Compressor operates 100% inside your browser using HTML5 Canvas APIs. Your photos never leave your phone or computer.

How does the target size (20KB, 50KB) compression work?

Our intelligent binary search algorithm iteratively samples encoding parameters within milliseconds. It determines the highest possible visual quality and dimensions that satisfy your exact target size without manual trial and error.

Is this tool free for government exam form uploads?

Yes! Most Indian government exam portals (UPSC, SSC, IBPS, State PSC, NTA) require passport photos between 20KB and 50KB. Use the one-click 20KB or 50KB preset buttons to get application-ready files in seconds.

Will compression reduce image clarity?

Our algorithm prioritizes perceptual sharpness by removing invisible metadata and optimizing color quantization first. You can use the live Before/After comparison toggle to verify sharpness before downloading.
