Drop any JPG and we'll squish it using mozjpeg — the same optimizer Google's Squoosh uses, running in your browser. You can set a quality level (1–100) or a hard target size in KB.
For most photos, quality 75–85 is visually identical to the original at roughly half the size. Below 50, most people start noticing artifacts around edges.
Frequently asked questions
How much can a JPG be compressed?
Typically 40–70% size reduction with no visible quality loss. Photos from smartphones often shrink the most because they ship with very high quality settings.
Will my EXIF data be preserved?
No — our compressor strips metadata. This is usually what you want; it makes the file smaller and removes location data before sharing.
What if I need the smallest possible file?
Set a target size (100 KB, 500 KB, etc.) — we'll binary-search quality to hit it.
