Compress multiple images entirely in your browser. JPEG/WebP use adjustable quality; PNG uses color‑palette optimization (via UPNG). No uploads or watermarks.
2) Flow
Drag & drop up to 20 images (JPG, JPEG, PNG, GIF, HEIC, WebP).
Each file gets compressed automatically with smart defaults.
Use “Edit” to fine‑tune quality or set a max size per file.
Download individually, or “Download All” as a ZIP.
3) Sanity checks
PNG is lossless—size depends on color count and pixels; photos compress better as JPEG/WebP.
Animated GIFs are flattened to a single frame preview here.
HEIC is treated like other raster inputs once rendered to canvas.
4) Shortcuts
Resize very large photos before compressing for better results and smaller files.
For logos/UI with transparency, keep PNG; for photos, prefer JPEG/WebP.
5) Pitfalls
Over‑compressing JPEG introduces blockiness; balance with modest resizing.
Too few PNG colors can band gradients; increase palette slightly if needed.
6) Micro examples
Photo 4032×3024 → compress to JPEG 70–85 quality for dramatic savings.
Logo 1600×600 PNG → reduce to ~60–120 KB with palette optimization.
