FAQs

What image formats are supported?▼
The tool accepts common image formats including JPG, PNG, GIF, and WebP. All images are converted to WebP format during optimization for better compression.
How do I set custom dimensions?▼

In Crop & Resize mode:

  • For custom aspect ratio: Select "Custom" and enter width/height values
  • For custom dimensions: Select "Custom" from the Output Image Width dropdown and enter the pixel value

In Keep Original mode: Dimensions are automatically maintained from the source image.

What's the filename format for downloaded images?▼
Downloads use the format: originalfilename-YYYY-MM-DD-HH-mm-ss.webp, preserving the original name while adding a timestamp.
Why are my aspect ratio and Output Width selections reset?▼
When switching to Crop & Resize mode, the tool defaults to Square (1:1) aspect ratio and 600px width for consistency. You can change these after switching modes.
Is my data actually private?▼
Yes, absolutely. We do not upload your images anywhere. All processing happens entirely in your browser. Nothing leaves your device unless you choose to share your feedback or bug report via form submission.
Can I optimize multiple images at once?▼
Currently, the tool processes one image at a time. Select a new image after completing the optimization of the current one. Since all optimization processes happen on your device, enabling multi-select would cause performance issues. High memory usage in your browser could lead to unresponsive tabs.
