Self-hosted. Your images never leave your network.

Frequently asked questions
- How much can I compress an image without losing quality?
- Most JPEG images can be compressed to 70-80% quality with no visible difference. PNG files can often be reduced 30-50% with lossless optimization. The live preview lets you judge quality before saving.
- How do I compress an image to a specific file size?
- Use target size mode and enter your limit (e.g., 200KB). SnapOtter automatically finds the right quality level to hit your target while maximizing visual quality.
- Does compression change the image dimensions?
- No. Compression reduces file size by optimizing encoding, not by changing pixel dimensions. Your image keeps the same width and height.
