Image Compressor
Reduce image file size while keeping quality.
Shrink JPEG, PNG and WebP images by up to 90% without losing visible quality, using a fast in-browser compressor that respects your privacy. Whether you’re prepping product photos for a store, attachments for an email, or images for a website, smaller files mean faster pages and lower bandwidth.
Use the tool
What this tool does
Image compression reduces file size by re-encoding the picture with smarter color and quality settings. Our compressor runs in the browser using the Canvas API — your images are never uploaded. You pick a quality target, the tool re-encodes locally, and you download the smaller version.
Why people use it
- Web pages with optimized images load dramatically faster, improving SEO and Core Web Vitals.
- Email providers reject attachments above ~25 MB; compression keeps you under the limit.
- Mobile data plans are expensive in many countries — smaller images respect your readers’ bandwidth.
- Cloud storage costs add up; compressing before upload saves money long-term.
- Social platforms re-compress what you upload anyway — feeding them an already-optimized file gives you cleaner results.
Step-by-step guide
- Open the Image Compressor tool from the home page.
- Drag your image file in or click to select it from your device.
- Adjust the quality slider — 70–80% is typically indistinguishable from the original.
- Preview the new file size and visual quality.
- Click ‘Download’ to save the optimized image to your device.

Frequently asked questions
Does compressing reduce image quality?

Are images uploaded anywhere?
No. Compression happens locally in your browser using the Canvas API. Files never leave your device.
Which formats are supported?
JPEG, PNG and WebP input and output. PNG with transparency is preserved.
Can I batch compress?
The current version compresses one image at a time. Batch mode is on the roadmap.
