FreeConvert GIF Maker vs OpenImageIO

FreeConvert GIF Maker creates animated GIFs from uploaded images in a web browser. It supports JPG, PNG, WebP, and HEIC files, which users can choose from Dropbox, Google Drive, or OneDrive, or provide through a URL. The editor lets users order frames, set delays and loop count, choose GIF width, and add crossfades. Per-image controls include margins, skipping, and duplication; output options cover alignment, trimming, fill color, frame stacking, and compression. Finished GIFs can be downloaded or saved to Google Drive, OneDrive, or Dropbox; mobile users can download through a QR code. The maker page displays a 1 GB maximum file size and prompts users to upgrade for more. The free plan includes 20 conversion minutes per day, a five-minute-per-file limit, and up to 20 files per day. Paid plans start at $12.99 a month. FreeConvert says uploads use SSL encryption and created files are automatically deleted after eight hours. The maker works in modern Windows, Mac, iOS, and Android browsers; no desktop application is listed.
