Image Compress
Reduce JPG, PNG, or WebP file size in your browser. Compression runs locally via a Web Worker — your images never leave your machine.

Image compression reduces a photo's file size so it loads faster on web pages, fits an email attachment limit, or saves storage. The ToolEdge Image Compress tool runs entirely in your browser — drop a JPG, PNG, or WebP, pick a quality target, and download the smaller version. The image is never uploaded; everything happens locally via the Canvas API and a Web Worker so your tab stays responsive even for large photos.
Modern compression isn't just "lower quality" — it's a binary search for the highest quality that still hits your target file size, run by a Web Worker so the UI doesn't freeze. JPG and WebP support quality-based compression natively; PNGs can be re-encoded as quality-tier WebP for dramatic savings while keeping transparency. Most photos shrink 60–90% with no visible quality loss because phone cameras default to extremely high quality.
Common use cases
- Compressing phone photos before emailing — most email services cap at 25 MB total.
- Optimizing images for a website to improve page load speed (the single biggest Core Web Vitals lever).
- Reducing screenshots before pasting into a shared doc or Notion page.
- Shrinking product photos for a Shopify, Etsy, or marketplace listing where stores have per-image size limits.
- Preparing scanned documents (saved as JPG) for upload to portals with strict size caps.
