Instantly compress photos and shrink image sizes for email attachments. Bypass Gmail and Outlook's 25MB limits by optimizing your files for fast, error-free sending.
Perfect for professionals sending scanned documents, photographers sharing image proofs, or anyone trying to attach a batch of heavy smartphone photos via Gmail, Outlook, or Apple Mail.
There is nothing more frustrating than writing a detailed email, attaching your photos, and getting hit with a 'File Size Exceeds Limit' error. Email providers like Gmail and Outlook strictly cap attachments at 20MB to 25MB. Because modern smartphone cameras take massive, high-resolution photos, attaching just 3 or 4 pictures can block your email from sending. Our email image compressor is specifically designed to fix this. By defaulting to a smart 800-pixel maximum width—which fits perfectly inside the reading pane of most email clients—and a balanced 50% JPEG quality, you can drastically shrink heavy megabyte photos down to a few lightweight kilobytes. Plus, because processing happens entirely locally in your browser, you never have to wait for slow server uploads when you are in a rush to hit 'Send'.
Optimized images that balance quality and file size for faster uploads — with exact target sizes, AVIF/WebP/MozJPEG codecs, and unlimited batch ZIP export.
