- What format is best for iOS lock screen wallpaper?

- Will compression break transparency or animation?
- Transparency is preserved when the output format supports it (PNG, WebP, AVIF). Animation is preserved for animated WebP. JPEG output flattens transparency to white.
- Can I compress dozens of images at once?
- Yes — use the bulk compressor. Drop a folder or multi-select files; the queue processes them in order with progress per file, and you can download all results as a ZIP.
- Do my images get uploaded anywhere?
- No. The tool runs entirely in your browser — important for client work, internal assets, and anything not yet published.
