Image Compressor

Shrink a photo by quality or hit an exact target size in KB, MB, or GB, and convert between JPEG, PNG, and WebP. Runs entirely in your browser — nothing is uploaded anywhere.

Higher = better quality, larger file. Lower = smaller file, more compression artifacts.

The tool searches for the highest quality that stays at or under this size. Very small targets may require shrinking the image's dimensions too.

Compression and format conversion happen using your browser's built-in Canvas API — the image never leaves your device. PNG is a lossless format with no quality setting, so "by quality" instead scales its dimensions down, and "by target size" does the same via a search rather than adjusting compression artifacts.
