XConvert Image Compressor
XConvert Image Compressor is a web-based tool for compressing, resizing, and converting images, with batch processing and API access. It supports formats including JPG, JPEG, JFIF, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, ICO, PPM, EPS, and several RAW formats. Images can be uploaded from a computer, Google Drive, or Dropbox. Compression can be combined with conversion to JPG, WebP, AVIF, PNG, or HEIC; metadata controls and Auto Scale are also available. Auto Scale adjusts dimensions to meet a target file size while maximizing quality. Free users can compress images up to 300 MB each, with no per-session file-count cap. Free video conversions are also offered: visitors get 30 daily, and free accounts get 60. Basic costs $4.99 a month or 49.99 USD yearly; Pro costs $9.99 a month or 99.99 USD yearly. The service says uploads use TLS in transit and files are automatically deleted after a few hours. No account is required for the online tool, and an XConvert desktop app supports offline conversion and editing.
