Bulk Image Tools – Convert or Compress Images in Batches
Two tools here work on many images at once and return the results in one ZIP. The Bulk Image Converter changes a batch from one format to another: JPG, PNG, WebP, AVIF, GIF, BMP, HEIC or SVG files in, one target format out. The Bulk Image Compressor accepts mixed formats and adjusts encoding quality, or tries to bring JPG, WebP and HEIC files under a size target without resizing; a file that can't reach the target is marked 'target not reached'. PNG is lossless, so it may not get smaller, HEIC is converted to JPG, which can be larger than the original, and AVIF is re-encoded only in browsers that support it. Everything runs in your browser: no server upload, no login, no watermarks.
