This Image File Size Increaser helps you make a photo file bigger in KB or MB directly in your browser. It is useful when a form, exam portal, job application, document upload page or online profile asks for an image file with a minimum file size. Upload your image, enter the target size, and download the increased file without installing software.
The tool keeps the original image pixels the same and adds safe extra data to increase the file size. That means it is designed for file size requirements, not for improving sharpness or increasing photo resolution. For best results, use JPG, PNG, WebP or GIF images and choose a target size that is larger than the original file.
Best Uses
- Increase image size in KB for upload forms.
- Make JPG, PNG, WebP or GIF files bigger in MB.
- Set a target file size quickly with 100 KB, 500 KB, 1 MB, 2 MB and 5 MB presets.
- Keep the photo preview and original visual quality unchanged.
Why This Tool Is Useful
- No image is uploaded to a server; processing happens locally in the browser.
- Works with simple target size and add-size modes.
- Shows original size, final size, added data and image dimensions.
- Clean output filename and instant download button.
How to Increase Image File Size
Select an image, choose Target Size if you need a specific final file size, or choose Add Size if you want to add a fixed amount of KB or MB. After clicking Increase Image, the tool prepares a new file and enables the download button. If the target size is smaller than your original image, enter a larger value because the tool is made to increase file size only.
Important Note
Increasing file size does not make a blurry image clearer. It only changes the file weight. If you need better print quality, use a high-resolution image first, then use this tool only when a website requires a larger file size.
