Compress JPG for Web

Worked example

Example: compress a 2.8 MB hero JPG at 80% quality WebP export—often under 500 KB for blog headers.

When to use this

• Blog hero and inline images.
• Landing page background photos.
• Thumbnail grids in content-heavy sites.

Common examples

• 2.8 MB hero JPG at 80% quality WebP → often under 500 KB for blog headers.
• 4 MB product PNG → JPEG export at 85% for catalog listings when transparency is not needed.
• Batch of blog images resized to 1200 px wide then compressed → faster LCP on static sites.
• 1.8 MB team photo → WebP at Balanced for about 200 KB on careers page.
• Ecommerce PNG with transparency → compress without converting to JPEG when alpha matters.

Common mistakes

• Compressing without resizing to rendered dimensions.
• Using progressive JPEG settings inconsistently across a site.
• Over-compressing faces and product detail in ecommerce.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs on your device—files are not uploaded or stored.

Limitations

Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

Privacy and file handling

Your image stays on your device and is not uploaded.
