How to Make Website Pages Load Faster
Speed up pages with In-browser image resize, compression, and format conversion — the highest-impact levers DevToolKit actually provides.
Images dominate weight
Most slow marketing pages carry oversized hero photos and unoptimized thumbnails. DevToolKit's browser-based resizing, compression, and conversion tools address that directly; Background Remover is a separate server-backed, AI-assisted workflow.
This guide does not cover meta-tag analyzers or HTML minifiers; they are not in the catalog. Focus on bytes in images first.
Resize to display dimensions
Image Resizer exports pixel widths that match CSS layout — a 2400px file displayed at 600px wastes download time. Resize before compressing.
Compress with preview
Image Compressor lowers quality settings until artifacts appear, then back off one step. Check text overlays and faces, not just file size numbers.
Modern formats
PNG to WebP often shrinks photos and graphics for CDN delivery. Keep lossless masters separately. WebP to PNG helps when a legacy CMS rejects modern formats.
Skip Server-backed steps for speed work
Background Remover is Server-backed — unrelated to page weight after export. Optimize the flattened asset with compress and convert instead.
Speed checklist
Hero and card images resized; compression preview acceptable; WebP served where supported; lazy loading enabled in markup; repeat audit after content edits.
