Under1MB - Convert and compress images

What is Under1MB - Convert and compress images?

Under1MB is a client-side image toolkit — convert, compress, and resize images using nothing but your browser's own image engine. No backend means no upload step and no "we delete your files" policy to trust, because we never receive them. Type a target size (500KB, 1MB, whatever your form needs) and it finds the highest-quality file that fits. Batch 40 files into one ZIP. 11 formats, including HEIC and AVIF. Free and unlimited — the product is a browser tab, not infrastructure.
