25MB is the hard email attachment ceiling for Gmail and a common cap on file-sharing services and professional photo submission portals. Huge RAW scans, drone images, and ultra-high-resolution product photography routinely exceed it.
ImageMint's Target Size tool strips just enough data to land under 25MB without visible quality loss — binary-search-based and fully local.
How to Compress
- 1
Upload Your Image
Drop your multi-gigapixel or RAW-derived source. The browser will stream decode it.
- 2
Set Target to 25MB
Enter 25600 (KB). JPEG at quality 92+ is the recommended profile.
- 3
Download the Result
Attach to email or upload — under 25MB guarantees Gmail acceptance.
Tips
- Gmail's 25MB cap is post-encoding — include inline images and base64 overhead in your budget.
- For email, JPEG remains the universal compatible format. PNG/TIFF may exceed 25MB at any resolution.
- If the recipient's server also has a limit, use cloud links for anything approaching 25MB.
FAQ
Does Gmail really cap at 25MB?
Yes — Gmail enforces a 25MB per-message attachment cap and auto-offers Drive links above that.
Will compression damage a scanned document?
No — at quality 92+ the result is indistinguishable from source for typical document scans.
Can I compress multiple files to fit 25MB total?
Yes. Batch compress and manually size the outputs so their total sits under 25MB.
