When to use compression

Compression is best when you need smaller files without changing pixel dimensions. It helps reduce storage costs, speed up web delivery, and meet upload size limits.

  1. Upload an image and choose quality or target size mode.
  2. Preview the result to confirm acceptable quality.
  3. Download the compressed file and use it on your site or in email.

How compression works

Compression reduces file size by removing redundant information from your image. This is ideal for faster page loads, smaller email attachments, and storage savings. ImageTools offers two modes: quality mode for fine-tuning visual fidelity, and target size mode to aim for a specific file size.

  • Use quality mode when you care about precise visual appearance.
  • Use target size mode when you must stay under a strict size limit.
  • Resize large images first if the pixel dimensions are oversized.

Compression FAQ

Does compression reduce image quality?

Compression can reduce quality if settings are too aggressive. Start around 80 and lower gradually while checking details.

Should I resize before compressing?

Yes. If the image dimensions are larger than needed, resize first to avoid wasting bytes on unused pixels.

Which format should I export?

Use JPG for photos, PNG for crisp graphics or transparency, and WebP for modern browsers that support it.
