Image Compressor
Make images load faster by reducing file size without sacrificing quality. Compress JPG, PNG, WebP and AVIF in your browser — nothing is ever uploaded.
Recommendations
- Use the preview to compare before and after at the exact size you will publish.
- Keep the original file as a master copy and optimize a separate version for the web.
- Batch process multiple files to save time on recurring tasks.
Pro Tips
- Aim for a quality value between 70 and 80 for photos to balance size and clarity.
- Resize to the exact dimensions you need before compressing for the best results.
- For text and logos, prefer PNG or WebP to keep edges sharp.
