Increase Image Size in KB Without Losing Quality
Make a JPEG or PNG file bigger in KB without changing pixel dimensions, DPI, or quality. Built for passport, visa, and government portals that reject photos for being below a minimum file size.
Portals That Enforce a Minimum File Size
| Portal | Minimum Size |
|---|---|
| India passport & visa (VFS) | 10 KB |
| India NEET / other exams | 20 KB |
| India PAN card application | 20 KB |
| Various Indian government forms | 10 – 50 KB |
Minimums change — verify with the portal's official help page before submitting.
How to Make a Photo Bigger Without Changing Pixels
Find the required minimum
Check the portal's instructions. A common requirement is "photo must be between 10 KB and 20 KB." If your photo is below the minimum, upload it here.
Enter the target size
Type the minimum size the portal requires. The tool re-encodes your image as JPEG at quality 95% and pads it with JPEG comment segments to reach the target.
Download and upload
Download the new JPEG and submit it to the portal. The photo looks identical to the original — only the file size is different.
Need a passport photo that also passes dimension and background checks?
This tool fixes file size only. If your portal also checks pixel dimensions, head position, or background color, you need a compliant photo first. Our $1 passport photo tool handles all of that.

Why would I need to increase an image file size?
Some government portals enforce a minimum file size on uploaded photos. Indian passport applications, for example, require photos between 10 KB and 20 KB — a clean white-background photo can compress below 10 KB, which gets rejected for being "too small." This tool pads the file back up to the required size without changing the pixels.
How does padding work without changing the photo?
JPEG files allow comment segments (COM markers) that are ignored when the image is decoded. The tool adds these comment bytes to reach your target file size. The pixels, dimensions, colors, and visible image stay byte-identical — only the file size changes.
Will the padded photo pass my portal's checks?
For most portals, yes. Some portals re-process uploaded photos (re-encode them server-side), which strips the padding. If your portal does this and your photo still fails the minimum size check, try using a less-compressed source photo instead.
Can I upload a PNG and get a padded JPEG?
Yes. The tool re-encodes your file as JPEG at quality 95%, then pads it. You'll see the output labeled with JPEG format regardless of what you uploaded.
Does the image quality change?
If you upload a JPEG, the re-encode at 95% may introduce very minor quality loss. If you upload a PNG, it's converted to JPEG at 95% quality, which is visually lossless for photos. Padding itself adds zero quality loss because it only appends metadata bytes.
Is my photo uploaded to a server?
No. Everything happens inside your browser. Nothing is sent anywhere.
