Compress Images for Email — Free Online Tool
Stop getting bounced-back emails. Shrink your photos before attaching them.
Most email providers cap attachments at 20–25 MB, and many corporate servers allow even less. A single uncompressed photo from a modern phone can be 5–12 MB. That's one photo per email.
EasyFileKit compresses your images entirely in your browser — Your files are processed entirely in your browser — never uploaded to a server. Pick the target size that fits your email provider and attach away.
How to do it
- 1Choose a target size below that matches your email provider's limit.
- 2Upload your photo(s) — you can process multiple files at once.
- 3Download the compressed versions, ready to attach.

Frequently Asked Questions
What is the max attachment size for Gmail?
Gmail allows attachments up to 25 MB total per email. If your photos exceed this, compress them or use Google Drive to share a link instead.
How do I compress multiple photos for one email?
Use the Image Compressor tool — it supports batch processing. Upload all your photos at once and download them as a ZIP file.
Will compression make my photos look bad?
Not at our moderate compression levels. Compressing to 500KB or 1MB keeps photos looking sharp on screens. Only extreme compression (under 50KB) noticeably reduces quality.
