Compress Images for Email

Shrink photos before emailing them. Most providers reject attachments larger than 25 MB — Converter.Plus compresses JPG, PNG, and HEIC images to email-friendly sizes in your browser.

Why your photos are too big to email

Most email providers cap attachments at 25 MB total (Gmail, Outlook) — some are stricter at 10 MB. A typical iPhone photo is 2–4 MB; five photos and you're already bumping the limit. Compressing before sending solves the problem permanently and produces smaller, faster-to-download attachments for your recipients.

How to compress photos for email in two minutes

Open Converter.Plus's image optimizer, drop the photos onto the upload area, and pick a quality preset. Quality 80 is visually identical to the source for typical phone photos and shrinks them to roughly 200–400 KB each. Click Download All for a ZIP of compressed JPGs ready to attach.

iPhone photos and HEIC

If your photos are saved as HEIC (the iPhone default), most Windows and Android recipients can't open them. Run them through the HEIC to JPG converter first, or skip straight to the image optimizer which auto-detects and decodes HEIC.
