Need to get a photo under 3 MB? This free tool compresses JPG and JPEG images to 3 MB or smaller, right inside your browser. It automatically tests different quality levels and keeps the sharpest result that still fits within 3 MB, so you do not have to guess. It is ideal for email attachments, web forms, marketplace listings, and visa or government portals that reject files larger than 3 MB. Because every image is processed locally on your device, nothing is ever uploaded to a server and your photos stay completely private.

Frequently Asked Questions
How do I compress an image to 3 MB?
Upload your JPG or JPEG photo and the tool instantly searches for the highest quality setting that keeps the file at 3 MB or below. You can preview the result and download it in one click, with no settings to adjust by hand.
Is it free to compress images to 3 MB?
Yes. Compressing images to 3 MB is completely free with no limits, no watermarks, and no sign-up. You can compress as many photos as you like.
Will compressing to 3 MB lower the quality?
The tool keeps quality as high as possible while meeting the 3 MB target. For most photos the difference is hard to notice, though very small targets naturally need more compression than larger ones.
Are my images uploaded to a server?
No. All compression happens locally in your browser, so your images never leave your device. That makes it safe for private or sensitive photos and it works even on slow connections.
What can I use a 3 MB image for?
A 3 MB limit is common for email attachments, online application forms, forum avatars, marketplace listings, and content systems like WordPress. Compressing to 3 MB helps pages load faster and avoids upload rejections.
