What this image compressor does
This free image compressor reduces file size for JPG, PNG, and WebP images directly in your browser. It is designed for people who need smaller files for websites, blog posts, email attachments, ecommerce product galleries, CMS uploads, landing pages, and performance-focused frontend work.
The tool keeps your existing image dimensions and focuses on file-size reduction. For JPG and WebP output, you can lower quality to push file size down further. For PNG, compression gains may be smaller because PNG is a lossless format.
How image compression works
1
Load the image locally
Your JPG, PNG, or WebP file is opened in the browser so the compressor can inspect the pixels and preserve your original dimensions.
2
Apply compression settings
You choose whether to keep the source format or export to JPG, PNG, or WebP. For JPG and WebP, the quality slider controls the balance between detail and file size.
3
Preview and download
The browser renders a new file, strips unnecessary metadata, and gives you a live before-and-after preview so you can download the optimized result immediately.
Example compression workflow
Input
- Format: JPG hero image
- Dimensions: 1800 × 1200 px
- File size: 1.9 MB
- Goal: faster page load for a landing page
Output
- Format: WebP
- Dimensions: 1800 × 1200 px
- Quality: 76%
- Typical result: much smaller file with a visually close match for web delivery
This is a common workflow for blogs, portfolios, product pages, app dashboards, support docs, and email-ready media where smaller files improve load time and upload speed.

FAQ
Does this image compressor upload my file?
No. Compression happens locally in your browser. Your image stays on your device unless you choose to upload it somewhere later.
What output format gives the smallest file?
WebP usually delivers the best size reduction at a similar visual quality. JPG is still useful for compatibility, while PNG is best when you need a lossless or transparency-friendly format.
Will compression reduce image dimensions?
This tool focuses on file-size compression, not resizing. It preserves the original pixel dimensions. If you need to shrink dimensions too, use the Image Resizer & Compressor tool.
Why does PNG sometimes stay large?
PNG is lossless, so browser compression options are limited. If you need much smaller output, converting to WebP or JPG is usually more effective than exporting another PNG.
