Frequently Asked Questions
What JPG quality setting should I use?
Start around 75–85% for photos: smaller files with little visible loss. Go lower only if you need minimum size (e.g. thumbnails); raise it if you see banding or blur.
Does compressing an image ruin quality?
Lossy compression (JPG) discards detail permanently. Keep originals safe; export a new compressed copy for web or chat. PNG compression is typically lossless for this type of tool.
Are my images uploaded to a server?
No. Compression runs in your browser; files stay on your device.
Does this work for PNG and JPG?
Yes. Upload common raster formats and download a smaller file after tuning quality. Very large images may take longer depending on your device.
