Compress images for email

Corporate inboxes still cap attachments. Drop quality slightly or convert photos to JPEG/WebP so threads deliver reliably—preview size before you attach.

How it works

1

Upload Image

Click or drag an image into the drop zone — JPG, PNG, WebP, or BMP.

2

Compress

Hit "Compress" to reduce the file size. Adjust quality or format in settings.

3

Download

Save the compressed image instantly. Everything stays in your browser.

Mailbox realities

Recipients on mobile mail apps appreciate lighter downloads. Aim far below your provider’s ceiling so forwarding chains do not bounce.

Inline vs attachment

Heavier inline images still count toward bandwidth on some clients. Compression helps whether you attach files or paste into the body.

Frequently asked questions

Is this image compressor free?
Yes, completely free. No account, no limits, no watermarks.
Are my images uploaded to a server?
No. Everything runs locally in your browser. Your files never leave your device.
Will compression reduce the quality?
Slightly, depending on your quality setting. At 80% quality the difference is usually not visible to the naked eye.
Which format should I use?
WebP gives the best size/quality ratio for most images. Use JPEG for photos and PNG when you need transparency.
Does compressing images help with SEO?
Yes. Smaller images improve page load speed and Core Web Vitals, both of which influence Google rankings.
