Frequently Asked Questions

To increase image size in KB, upload your JPG, PNG, or WebP file to SizeIncreaser, enter your desired target size (e.g. 100 KB, 200 KB, or 2 MB), and click "Increase File Size". The tool processes your image directly in your browser and lets you download the increased file immediately.

SizeIncreaser uses smart lossless padding and high-quality re-encoding. For raster images (JPG, PNG, WebP, AVIF), it preserves visual clarity while embedding safe, standard-compliant metadata markers (such as JPEG COM segments and PNG paDd chunks). Your image retains its sharpness and visual appearance while reaching the exact target file size in KB.
