Increase Image File Size

Increase a photo's file size to an exact target in KB without changing how it looks or its dimensions. For forms that require a minimum image size — the opposite of a compressor.

How to use Increase Image File Size

  1. Upload your photo.
  2. Enter the target size in KB (e.g. 20 or 50).
  3. Download the resized file — same image, larger file size.

Frequently asked questions

Why would I need to increase an image's file size?

Many exam and government upload forms require a photo to be at least a minimum size (e.g. "20KB to 50KB"). If your photo is too small, the form rejects it. This tool pads the file up to the size you need.

Does it change how my photo looks?

No. The pixels and dimensions stay exactly the same — the tool adds standards-compliant filler data (a JPEG comment segment) that every viewer ignores, so only the file size changes.

Is the file still a valid image?

Yes. It remains a valid JPEG that opens everywhere and passes upload checks; we simply enlarge the file to your target byte size.

Are my files uploaded to a server?

No. This tool runs 100% in your browser. Your files never leave your device, which makes it fast and completely private.

Is this tool free for commercial use?

Yes. All PikFinder tools are free with no sign-up, no watermarks, and no usage limits. Files you process belong entirely to you.
