FreeFileConvert performs conversions in the cloud: its own page says all conversions are done in the cloud and you simply upload your file, with a free cap of up to 5 files and 1 GB combined and metered conversion minutes. A browser-based converter does everyday image and PDF jobs on your own device with no upload and no cap.

Open PDF to JPG / PNG →FreeFileConvert states that all conversions are performed in the cloud, so you upload your file to be processed; its free tier limits you to up to 5 files and 1 GB combined and can show "No conversion minutes remaining". A client-side converter skips the round trip entirely, opening your image or PDF locally and converting it in the browser, so there is no upload, no combined-size cap and no metered minutes.
The local route is the better fit when the file is private, when you have hit a free-tier minute or file cap, or when you would rather not create an account. FreeFileConvert supports thousands of conversion combinations including audio and video, so for those it may be the tool you need; for common web image and PDF conversions, the free local option covers them.
