Hey everyone! I’ve been working hard this week on revamping my online illustration portfolio, but I've hit a frustrating roadblock with performance. My digital paintings are exported directly from Photoshop as high-detail JPEGs, often weighing between 12MB and 16MB each. When I put together a multi-image gallery page, the total page weight explodes past 150 megabytes, causing terrible mobile loading lag and high bounce rates. I want to optimize these assets quickly, but I'm super protective of unreleased artwork and hate uploading raw files to random cloud servers. Is there a reliable browser-based utility where I can compress jpg files locally on my machine without installing bloated software suites?
