What is Compress JPG / JPEG photos online?
TL;DR: Shrink44 compresses JPG and JPEG photos up to 80% smaller in your browser with quality, resolution and target-KB controls — perfect for email, social media and websites.
JPG compression is the most common image optimisation task on the web. Photos straight from a phone or DSLR are typically 3–10 MB each, far too large for fast page loads, mobile uploads or email attachments.
Shrink44's JPG compressor uses the HTML5 Canvas API to re-encode JPEGs at your chosen quality, optionally resizing the longest side to 4K, Full HD or HD, and writing the result with high-quality JPEG encoding. It supports targeting an exact KB or MB output size using iterative binary search.
Use Shrink44 to compress JPG photos for websites and e-commerce, WhatsApp / Instagram / LinkedIn uploads, email attachments, cloud storage backups, or passport / visa application forms that require a specific KB size.
