Image Compressor — In-Browser
Compress JPG, PNG, or WebP images entirely in your browser. Drag in a file, pick output format and quality, download the result. Images never leave your tab — useful for sensitive images (screenshots with private data, customer-facing materials before publication).
How to use the Image Compressor — In-Browser
Drop an image. The tool re-encodes it to your chosen format and quality. WebP gives the smallest output for the same visual quality. JPEG is universal-compatible. PNG is best for screenshots and graphics with sharp edges. Max-width lets you downscale at the same time.
Shrinking images without an upload
Large images are the heaviest part of most web pages, and shipping a full-resolution photo where a compressed one would look identical wastes bandwidth and slows load times. The fix is to re-encode at a sensible quality and format — but uploading private images to an online compressor isn't always acceptable.
This compressor re-encodes JPG, PNG, or WebP entirely in your browser: pick the output format, set a quality level, optionally cap the width, and download the smaller file. Nothing is uploaded, so it is safe for screenshots with private data or unreleased assets. To choose the right quality first, compare levels with the JPEG quality comparator; to remove metadata while you're at it, see the metadata stripper.
Common use cases
- Page weight — shrink hero and content images to speed up load.
- Format conversion — re-encode to WebP for the smallest modern output.
- Private assets — compress sensitive screenshots without uploading.
- Downscaling — cap width to serve appropriately sized images.
- Email and upload limits — fit an image under a size cap.
