What this tool does
Image Compressor reduces image file size by re-encoding uploaded images with adjustable quality settings and a previewable output.

🗜️ Image Compressor
Reduce image file size in your browser. No upload — the image stays on your device.
Why it is useful
Smaller images load faster, email more easily, and are less likely to hit upload limits on forms, CMS dashboards, marketplaces, or social platforms.
How it works
The browser loads the selected image, draws it to a canvas, and exports a compressed JPEG or WebP-style output depending on the page options.
Best input
Use photos, screenshots, or large web images where a smaller file matters more than perfect pixel preservation.
Privacy note
Images are handled in your browser with local file APIs and canvas processing. This page does not intentionally upload your image.
Important limitation
Compression is lossy for many formats. Keep the original file if you may need full quality later.
Quick answers
Why did a PNG get larger?
Simple graphics and transparent images can already be compact. Try a different format or keep the original if compression does not help.
Does it remove metadata?
Canvas-based exports usually drop most metadata, but do not rely on this as a dedicated privacy scrubber.
Common Use Cases
Shrink photos before CMS upload
Compress large product or blog images so they fit upload limits and load faster on content pages.
Prepare email-friendly screenshots
Reduce bulky screenshots before attaching them to support tickets, invoices, or internal notes.
Compare WebP and JPEG output
Try a few quality settings and keep the smallest version that still looks acceptable for the final placement.
Image Toolkit workflow
Move between compressing, resizing, converting, cropping, encoding, favicon generation, resolution math, and palette extraction while keeping image pixels local to the browser.
