Free Image Resizer & Compressor - Use Online Without Installing

How to use this tool

1. Choose a JPG, PNG, or WebP image and apply a product-photo or email preset.
2. Compare measured JPG/WebP sizes at two quality settings, or choose your own size and quality.
3. Inspect the result full size and save individual files or a ZIP.

Real-world uses

• Resize product photos to a 1280-pixel long edge.
• Prepare several email attachments at once.

What to check

• The quality slider does not apply to lossless PNG output.
• Increasing pixel dimensions cannot recreate missing detail.

Common problems and fixes

The file did not get smaller

Choose a smaller long edge or adjust JPG/WebP quality; format changes alone do not guarantee savings.

File and input privacy
