Reduce image file size online when uploads fail or pages load slowly. Compress photos and graphics in your browser while keeping acceptable visual quality for web, email, and CMS uploads.
Smaller images improve LCP and email deliverability—compress before uploading to CMS or newsletters.
Resize oversized photos first, then compress for the best size-to-quality ratio.

How to use this tool
Upload your image, choose a quality or compression preset, preview if available, then download the smaller file.
Worked example
Example: reduce a 2.8 MB hero JPG to under 500 KB for a blog header without visible banding on a laptop screen.
When to use this
- Blog and marketing images over 1 MB.
- Email newsletters with large inline photos.
- Ecommerce listings with strict size caps.
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.

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 in your browser—files are not uploaded to a server.
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 data is processed in your browser and is not uploaded to our server.
