Frequently asked questions
- Results vary by image. A typical 4–5 MB smartphone photo compresses to 200–600 KB at balanced quality with no visible degradation for most uses.
- Very wide images (over 1600 px) may be resized as part of compression. Otherwise, pixel dimensions are preserved.
- The tool outputs JPEG, which is the most efficient format for photos. PNG files are converted to JPEG on compression.
