Increase Image File Size in KB or MB Online
Upload an image and enter a target size such as 9.77KB, 50KB or 1MB. The tool increases the image file size while preserving its dimensions.
What Does Increasing an Image File Size Mean?
Increasing an image file size means creating a larger file, for example changing a 6KB image into a file close to 20KB, 100KB or 1MB. This is different from resizing the image dimensions. Dimensions are measured in pixels, such as 1200×800, while file size is measured in kilobytes (KB) or megabytes (MB). This tool targets the file size while attempting to preserve the original image dimensions.
When Would You Need to Increase an Image File Size?
Some websites, upload forms or document systems may require an image within a particular file-size range. You may also need a specific file size for testing or compatibility with another system. Enter a target such as 9.77KB, 50KB, 500KB or 1MB and the tool will attempt to create an image as close as practical to that value.
File Size vs. Image Dimensions
File size and image dimensions describe different properties. Two images with identical pixel dimensions can have different file sizes because of their format, compression level and encoded image data. Increasing a file from KB to a larger KB or MB value therefore does not necessarily mean increasing its width or height. If you need to change pixel dimensions, use the image resize tool instead.
Why Might the Result Not Match the Exact Target?
Image file sizes depend on encoding and compression performed by the browser. For that reason, producing a file that matches an exact number of bytes is not always possible for every image. The tool attempts to get as close as practical to the requested size while keeping the image usable and preserving its dimensions.
How to Increase an Image File Size
- Choose an image from your device.
- Enter the target file size, such as 20, 100 or 1.
- Select KB or MB as the unit.
- Start the file-size increase process and wait for processing to finish.
- Check the resulting size and download the new image.
Tips for Choosing a Target File Size
- Check whether the destination requires a minimum size, an exact target or a maximum file size.
- Use KB for smaller targets and MB for larger files.
- If your goal is to change width and height in pixels, use an image resizing tool instead.
- Keep the original image if you may need its previous quality or file size later.
Frequently Asked Questions
Can I increase an image to 9.77KB?
Yes. Enter 9.77 and select KB. The tool will attempt to create a file as close as practical to that target.
Will increasing the file size change the image dimensions?
The tool is designed to target file size while preserving the original dimensions as much as possible. Increasing KB or MB is different from changing pixel width and height.
Can I set the target in megabytes?
Yes. Select MB and enter the required value, such as 1MB.
Will the result match the target size exactly?
Not in every case. Image encoding and compression can cause a small difference, so the tool aims for the closest practical result.
What is the difference between this tool and an image resizer?
This tool targets the file size in KB or MB. An image resizer changes the image width and height in pixels.
