Frequently Asked Questions
What is the difference between Lossy and Lossless compression modes?
Lossy compression slightly adjusts pixel quantizations to achieve dramatic file size reductions (up to 90% savings). Lossless compression strips metadata and optimizes color tables without changing a single pixel, preserving 100% original visual fidelity.
How does the Target File Size selector work?
Our smart compression engine runs an automated binary-search optimization loop over quality and dimension parameters to generate an output file that matches or stays below your specified KB/MB limit.
Can I compress multiple images at once?
Yes! Switch to Bulk Lossy or Bulk Lossless mode to process dozens of images in parallel and download them all in a single formatted .zip archive.
What happens if Lossless mode cannot reach my target file size?
If your target size is smaller than what 100% lossless optimization can achieve, the tool displays a helpful warning banner with a 1-click option to switch to Lossy mode.
Are my images uploaded to any server?
No. All compression algorithms execute 100% locally inside your web browser memory via HTML5 Canvas and WebAssembly.
