Compress Image to 20KB

The 20 KB target converts each image to WebP at aggressive quality with dimensions near 800 px. This fits batch tiny thumbnails, placeholders, and low-bandwidth previews across any source format. The tool auto-detects and applies the right conversion per input, defaulting to WebP for maximum efficiency at this extreme. Expect visible softening; reserve it for small display contexts. Ideal for large sets of preview images that must share a tiny uniform budget. Whether you are optimizing assets for a US-hosted site on AWS, Cloudflare, or Vercel, trimming email attachments for Gmail and Outlook, or submitting documents to federal portals, this tool keeps your files lean and your workflow fast — all without uploading anything to a server.

If you are working in the United States, file size matters for email providers like Gmail (25 MB attachment cap), Outlook, and popular US hosting platforms. Compressing images and documents before uploading to Amazon S3, Cloudflare, or Netlify keeps your bandwidth costs down and improves Core Web Vitals for American visitors on both fiber and mobile networks.

• Most US email services reject attachments above 25 MB — compress to stay under that limit without switching to Google Drive or Dropbox.
• For US-based e-commerce on Shopify, aim for product images under 200 KB to keep your Google PageSpeed score competitive.
• Social platforms popular in the US — Instagram, Facebook, X (Twitter), and LinkedIn — each re-encode uploads, so feed them the smallest high-quality source file you can.
• Many US government and healthcare portals restrict document uploads to 5–10 MB; pre-compressing PDFs avoids upload failures.
