How to compress an image to 1MB
The most common attachment cap in email, handled in one pass.
Add your images
Drag and drop, or click to browse. Up to 50 images per batch.
1MB per image
Photos are compressed to about 1MB each — enough quality for viewing, small enough to send.
Download
Save images one by one, or the whole batch as a ZIP.
The 1MB ceiling
Webmail services and many corporate mail servers reject attachments once they pass 1MB. It is the single most common cap people hit.
Private by design
Every operation runs inside your browser. Your images are never uploaded anywhere.

Quality kept where it shows

Compressing to 1MB — FAQ
What does 1MB mean here?
The binary convention: 1MB = 1,048,576 bytes. Every exported file lands at or under that size, or you get the closest possible result with a clear notice.
Is the target per image or for the whole batch?
Per image. Each file in the batch is compressed to the target on its own; a ZIP of results can be larger.
Do PNG files stay PNG?
No. Target compression needs a quality dial, so PNG (and GIF/BMP) sources export as JPG. JPG and WebP keep their format.
Is there a limit?
Up to 50 images per batch, each up to 30 MB.
