What this tool does
Large images slow uploads and may hit platform file size caps — compression reduces bytes with minimal visible loss.
Browser-based compression keeps photos on your device — nothing uploads to a server.
How to use it
- 1
Upload your image file locally.
- 2
Adjust quality slider to balance size vs. visual quality.
- 3
Download the compressed image — ready for Instagram, web, or email.
Quality settings
Start at 80% quality — most social posts look identical. PNG for graphics with text; JPEG for photos.
Compress before watermarking if both tools are in your workflow.
Tips
- Compare file size before and after — aim for under 1MB for most social posts.
- Keep an uncompressed master archive separately.
