FAQ
Are my images uploaded to a server?
No. All image compression happens locally in your browser using JavaScript and the HTML5 Canvas API. Your files never leave your device, ensuring complete privacy.
What quality setting should I use?
For web use, 70-85% quality offers a good balance between file size and visual quality. For print or archival, use 90-100%. For maximum compression (e.g., thumbnails), try 50-70%.
Does compression reduce image dimensions?
No. This tool only reduces file size by adjusting compression quality. The image width and height remain unchanged. Use the Image Resizer tool to change dimensions.
Can I compress multiple images at once?
Currently, the tool processes one image at a time. For batch processing, compress each image individually and download the results.
What file formats are supported?
The tool supports JPG/JPEG, PNG, WebP, and GIF formats. Output format matches the input format.
