Occasionally an upload requires a photo to be at least a certain number of megabytes. This tool raises your image to the MB minimum you set — re-encoding it at high quality and padding the file if it's still under target — so it satisfies the requirement.
The process runs in your browser, so your photo is adjusted without being uploaded anywhere.
How to use Increase Image Size in MB
Using Increase Image Size in MB takes only a few seconds and just four simple steps — no sign-up, no software, and nothing to learn:
- Set the minimum MB: Enter the smallest size the form accepts, like 1 or 2 MB.
- Add your image: Upload the photo that's under the minimum.
- Process: The tool brings the file up to at least your MB target.
- Download: Save the image at the required size.
What you can do with Increase Image Size in MB
Increase Image Size in MB is built to do one job well, and gives you everything you need to get it exactly right:
Reaches an MB floor. Raises a photo to the minimum megabytes a form needs.
Image stays usable. Padding sits after the image data, so the photo opens normally.
Quality maximised first. Real detail comes before any padding is added.
Free and private. Done in your browser with no watermark.
Meet a minimum-MB upload rule
Shrinking tools are everywhere; tools that grow a file to a minimum are rare. This one lets you clear a 'must be at least X MB' rule without re-shooting the photo.
Whether you need it once or every day, Increase Image Size in MB keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.
Everything runs in your browser
Unlike most online tools, Increase Image Size in MB never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.
That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.
