Use the latest stable release available for your device. Keep at least twice the selected file size free in browser storage and close memory-heavy tabs before processing unusually large files.
Fallbacks
Image processing uses an OffscreenCanvas worker when supported and a main-thread canvas fallback otherwise. Tools provide a clear browser-feature error when there is no safe tested fallback.
Mobile limits
Phones often expose less memory than laptops. SNS LocalTools applies a lower input budget on constrained devices, keeps actions within reach and preserves the selected files for retry while the page remains open.
Video limits
Video input must be playable by the browser. The current trim flow creates WebM in real time and may not be available in WebKit. No unsupported codec or lossless trim claim is made.
