Image Compressor
Compress an uploaded photo locally by adjusting quality and downloading a smaller file.
Compress photos with a visible tradeoff for one focused image job
Image compression is a balance between byte size and visible detail. This tool re-encodes the uploaded image as JPEG or WebP using a quality slider, then estimates the output size from the generated data URL.
For example, a 3 MB product photo might become a much smaller JPEG at 0.72 quality while still looking fine inside a card. The preview helps you stop before text, faces, or edges become visibly damaged.
Output limits and privacy
This is a quick browser-side compressor, not an archival editor. Transparent artwork and screenshots with sharp UI text may be better as PNG or carefully tuned WebP. The quality experiment stays local, so you can compare size and artifacts before deciding which compressed copy is safe to use. The estimated size gives you quick feedback before you upload the compressed asset to a performance-sensitive page.
Frequently Asked Questions
How does the image compressor work?
It redraws the image to canvas and exports JPEG or WebP at the quality setting you choose.
What should I check before using the output?
JPEG and WebP are lossy exports, so repeated compression can soften details.
When is this useful?
Use it to shrink oversized photos for web cards, email drafts, CMS uploads, and performance testing.
Are my files uploaded?
No. The tool runs in your browser, so the image is not sent to a server.
