Compress any image to 450KB or less automatically. For high-quality product photos, web banners and CMS uploads with a 450KB file size limit.
Drop your JPEG or PNG. At 450KB, large high-resolution images compress with excellent visual quality. Original dimensions displayed.
Binary search finds the highest JPEG quality at or under 450KB. Large camera photos typically achieve quality 84–92 at this budget — near-original quality for web display.
Review and download your 450KB image.
450KB is used by some file sharing platforms, CMS systems and e-commerce platforms that set non-standard limits between 400KB and 500KB. It is also a practical target when you want to stay well under a 500KB limit with a quality margin. At 450KB, full-resolution product and blog images achieve excellent quality.
For modern websites targeting good Core Web Vitals scores, individual images above 200KB can contribute to slow LCP (Largest Contentful Paint) times, especially on mobile. 450KB is reasonable for hero images on fast connections but may slow mobile page loads. If web performance is a priority, consider 200–300KB for hero images and 100KB or less for smaller elements.
No — pixel dimensions stay exactly the same. Only JPEG quality is reduced to achieve the 450KB target. For portals or systems that also specify pixel dimensions, resize the image to those dimensions before compressing.
A 1600×1200 pixel photo at 450KB achieves approximately JPEG quality 82–88 — visually excellent for web display and digital portfolios. A 1200×900 pixel image at 450KB reaches quality 86–92. Both are near-original quality results at typical web viewing distances.
Yes — 450KB is a good size for portfolio images where quality matters. At 1200×800 pixels, 450KB achieves JPEG quality 84–90, preserving fine detail in photography and design work. It is small enough to load quickly while large enough to showcase your work at high quality on desktop screens.
