Constraint Modes
Width-cap, height-cap, percent scale, and fixed boxes behave differently on portrait vs landscape sets. Decide whether to crop or letterbox before a shop SKU launch. Never overwrite masters—export a resized folder.
Change format after sizing with JPG to PNG, PNG to JPG, or the WebP Converter in the converters silo. Frames from video belong in the Video Frame Extractor first.
Quality Filters
Downscaling benefits from decent resampling filters; extreme upscales invent soft detail. For print, start from large masters rather than upscaling web exports.

Big File Sharing focuses on free one-off jobs, no mandatory signup, and short-lived temporary files instead of account-centric project history.
