Head to head
Two apps side by side, full answers, nothing truncated. Swap either side.
Convert to JPEG, PNG, WebP, HEIC, AVIF (Pro), or JXL/JPEG-XL (Pro), or keep the original format. Additional compression/input support includes GIF, TIFF, ICNS, SVG, PDF, and APNG; these are not listed as conversion targets.
JPEG, PNG, GIF (including animated GIF), SVG — optimized in place. Conversion between formats remains unverified.
Yes — batch compress or convert multiple images and folders. Free: 25 images/day after the 7-day full Pro trial; Pro: unlimited compressions.
Yes — drag multiple images or directories into the app; files are queued for optimization. No batch or daily limit is stated.
Yes — batch resize during compression using max width/height in pixels; 0 leaves that axis unconstrained. Both limits fit a bounding box, preserving aspect ratio; GUI never enlarges or crops. Search-indexed docs also list longest-side limits, 25%/50%/75%, custom scale, and original size. CLI supports width/height and aspect-ratio toggles. Available in Free (25 images/day) and Pro (unlimited).
Checked the available sources and found no traceable answer. That is not a “no”.
Yes — reusable presets store quality, save location, output formats, resize, and filename options. Free: default plus 1 custom preset; Pro: unlimited presets and multiple output rows. CLI supports preset import/export. Metadata handling remains global.
Checked the available sources and found no traceable answer. That is not a “no”.
Yes — results show original/output sizes and compression ratio. Pro adds side-by-side comparison with zoom, pan, and live compression-strength adjustment. Documentation places this after compression; a separate preview before saving is not established.
No — the free Mac app automatically optimizes and saves files in-place; there is no before-saving comparison stage. Originals are moved to Trash for recovery.
Free retains metadata by default; Pro can preserve or strip EXIF/GPS and similar metadata through a global setting, rather than per preset. CLI offers preserve/strip flags. EXIF, XMP, ICC, IPTC, and copyright preservation is documented across WebP, AVIF, JXL, HEIC, PNG, and JPEG, including wide-color/HDR information.
Strips metadata by default, including EXIF/camera information, GPS, embedded authorship information and color profiles. Disable metadata stripping in Preferences to preserve it; selective removal by metadata type is not available.
Yes — WebP and AVIF conversion use six adjustable quality levels, Q1 (highest quality) through Q6 (smallest file), via the preset slider or CLI --level 1–6. WebP is available Free (25 images/day); AVIF output requires Pro or an active 7-day trial. AVIF, JXL, SVG, APNG, ICNS and TIFF inputs also require Pro/trial.

Scoring
Must-have factors weigh 5 and important ones 3; only these are scored, or the first five factors if none are marked. An app earns a factor's weight only when a cited source confirms it, and unknown cells count for no one. A pick is named only when the lead is larger than everything still unresolved could swing. Reading time assumes about 4 minutes per source. Full methodology
