About Image Format Conversion
Our image format converter supports conversion between all major image formats including PNG, JPG, WebP, AVIF, GIF, BMP, and more. Whether you need to convert for web optimization, compatibility, or specific platform requirements, our tool makes it easy. All conversions happen in your browser for complete privacy. 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.
Optimized for Users in the United States
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.
