✨ How It Works

  1. Upload your image — see original size and dimensions instantly.
  2. Resize (optional) — adjust width/height and keep “Lock Aspect Ratio” checked to avoid distortion.
  3. Choose Format — WEBP (default), JPEG for photos, or PNG for logos.
  4. Set Quality — try 80% for best results (usually 70–80% smaller).
  5. Preview & Download — confirm target size (e.g., Compressed: 99.9 KB).
Pro Tip: Use WEBP format for the smallest size and fastest site speed.

Frequently Asked Questions (FAQs)

How do I keep the aspect ratio locked?

The aspect ratio is locked by default, so the width and height adjust automatically when resizing. You can toggle this option in the settings panel if you prefer manual control.

What’s a good quality percentage for a blog?

For most blog or website images, start with a 70%–85% quality setting for JPEG or WEBP formats. This gives excellent balance between file size and clarity. For logos or images with text, keep it above 80% for sharper edges.

How can I compress an image to under 100 KB?

To compress an image to under 100 KB, lower the Quality slider and check the preview size indicator (Compressed: XX KB). If the file is still too large, reduce the Width (e.g., 1920px or 1280px) or switch to WEBP format — it’s highly efficient for web images.

Does WEBP keep transparency?

Yes, it does. The WEBP format supports transparency just like PNG, but with much smaller file sizes. It’s ideal for both photos and graphics requiring transparent backgrounds.

Do you store or keep my uploaded images?

No, never. Your images are processed locally in your browser — nothing is uploaded or stored on our servers. Your files stay private and secure on your device.



🏁 Final Takeaway

  • Preview before downloading — aim for under 100 KB.
  • WEBP = fastest sites; PNG = transparent logos; JPEG = photos.
  • Lock aspect ratio to keep images proportional.
