Optimizilla vs XConvert Image Compressor

Optimizilla is a web image-compression tool for JPEG, PNG, WebP, GIF, and SVG files. It processes images in the browser, supports batch work, and lets users adjust quality and preview the result before saving. The compressor uses format-specific handling: JPEG quality is inferred from quantization tables with a default target of 80; PNG files become PNG8 with up to 256 colors while preserving transparency; and animated GIF optimization reduces the palette while retaining frames. Compressed images have EXIF, GPS, and camera metadata removed. The site says files are not uploaded to its servers. Its free plan is free, with no registration, daily limit, or watermark, and is described as allowing unlimited compression. The pricing page also lists a 25 MB maximum file size and batches of up to 50 files for Free. Pro costs $9 a month and includes unlimited file size and batch uploads, among other tools. Enterprise pricing is custom and not listed; its plan includes custom integrations, without naming partners.

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.
