Two Intents, One Tool

Two Ways to Increase Image Size

"Increase image size" can mean two different things — pick the one you need.

01Megabytes

Make the File Heavier

If an upload form needs your photo to reach a specific file size — like a minimum of 1MB or 2MB — you need to increase the file's weight in megabytes without changing how it looks. This is common on government, visa, exam, and job-application portals.

Measured inMB / KB
02Pixels

Make the Photo Bigger

If your image looks too small or low-resolution, you want to enlarge its width and height — more pixels, a larger photo. This is the right choice for printing, displays, or any time the image itself needs to be physically bigger.

Measured inWidth × Height

This tool handles both. Set a target in MB to reach a required file size, or resize by dimensions to enlarge the actual photo.

How It Works

Step-by-step guide to enlarge a photo's dimensions or boost its file size to a target MB

Upload Your Image

Select one or more JPG, JPEG, PNG, or WebP files. Upload up to 12 images at once — no account or sign-up needed.

Choose Your Target

To increase a photo's size in MB, enter your target file size — say 1MB or 2MB — and the tool raises the image's weight to match. To make the photo physically larger instead, switch to dimensions and enter your desired width and height in pixels, cm, or inches.

“
A job portal demanded my photo be at least 1MB and mine kept getting rejected. This bumped it up in seconds and it finally went through.
“
Needed my scan to hit a 2MB minimum for a visa upload. Worked on the first try — couldn't believe how simple it was.
“
I love that nothing gets uploaded to a server. I was worried about privacy with my ID documents, but this processes everything locally on my device.
“
Hit the exact MB I needed in no time. I use it every time a form enforces a minimum file size.
“
Other sites just bloated my file with junk. This one raised the size to 1MB without any visible quality loss.

Frequently Asked Questions

Everything you need to know about image resizing

How do I increase image size in MB?

Upload your photo, enter your target file size in MB — for example 1MB or 2MB — and download. The tool raises the file's weight as close to your target as it can while keeping the image looking the same, so it clears portals that enforce a minimum megabyte requirement.

How do I increase image size to 1MB?

Upload your image, set the target to 1MB, and let the tool raise the file's weight toward that mark. The result usually lands just under 1MB — close enough to satisfy a minimum requirement without overshooting. PNG and WebP work the same way as JPG.

How do I make an image 2MB?

Enter 2MB as your target after uploading, then download the enlarged file. The tool increases the photo's size toward 2MB in a controlled way rather than just padding it, and a live preview lets you confirm the image still looks right before saving.

What's the difference between increasing size in MB and increasing dimensions?

Megabytes measure how much storage the file takes up; dimensions are how large the photo is in pixels (its width and height). Increasing MB makes the file heavier without changing how the image looks, while enlarging dimensions makes the actual picture bigger. They solve different problems — this tool does both.

Why do I need to increase my photo to a minimum MB?

Many official portals for visa applications, job submissions, and government forms reject files below a minimum size — sometimes stated as 'at least 1MB' or 'between 1MB and 5MB'. Raising your photo's size close to that limit helps it clear validation instead of bouncing back as too small.

How do I increase JPG size in MB?

Upload your JPG, enter the target megabytes you need — say 1MB — then download. A JPG size increase raises the file's weight toward your target while keeping the photo looking the same. PNG and WebP files work exactly the same way.

Can I increase image size without losing quality?

The algorithm preserves visual clarity while raising either the dimensions or the file weight in MB. For most targets the quality difference is unnoticeable. Use the live preview to confirm the result looks good before you download.

How close to my target MB will the result be?

The tool gets the file size as close to your target as possible without overshooting it. For a 1MB target you'll typically land just under that figure — close enough to satisfy a minimum requirement, never far below it.

What's the difference between increasing size in KB and MB?

It's the same operation in different units — 1MB equals roughly 1,000KB. Use KB when a portal asks for a smaller target like 100KB or 500KB, and use MB when the requirement is larger, such as 'at least 1MB' or 'minimum 2MB'. This tool accepts either unit.

Can I increase the size of multiple images at once?

Upload up to 12 images at once and process them in a single batch. This is especially useful when a submission needs several documents to each meet the same minimum MB requirement.

What does '100% Private — No Upload' mean?

Your images never leave your device. All processing happens entirely in your browser — nothing is sent to our servers. This matters most when working with passport photos, ID scans, or other sensitive documents you'd rather not hand to a website.

Which image formats are supported?

Upload JPG, JPEG, PNG, and WebP files. You can also convert between these formats on export, giving you full control over the final output format and size in MB.

Do I need an account or subscription?

The tool is free to use with no account required. There's an optional subscription for an ad-free experience and advanced AI-powered features, but the core MB size increaser is always free.

What other tools does ImResizer offer?

Beyond enlarging photos, ImResizer also lets you compress images below an MB limit, resize by exact pixel dimensions, crop, rotate, flip, and create passport or visa photos. All tools are free and process images locally in your browser.
