What Does “Increase Image Size” Mean?
Increasing image size here means increasing the file size, not the dimensions or visual quality. The image looks exactly the same — only the file weight changes to meet minimum upload requirements.

Frequently Asked Questions
How can I increase the size of an image in KB without losing quality?
You can use the Pixellize Image Size Increaser Tool. Upload your JPG, PNG, or WebP image, enter the desired size in KB, and the tool will increase the file size while keeping the image quality intact.
Can I increase the size of a WebP image using this tool?
Yes! Pixellize supports WebP, JPG, JPEG, and PNG formats. The tool maintains the original dimensions and transparency of WebP images while increasing the file size to your desired KB.
Is there a limit to the image size I can upload?
Pixellize works best with images under 10 MB, though most standard photos from cameras or smartphones will work fine. For very large images, it’s recommended to reduce the resolution slightly before uploading.
Will increasing the image size affect its width and height?
No. The tool only adjusts the file size in KB. Your image’s width, height, and DPI remain unchanged, so the visual quality and dimensions stay intact.
Can I use Pixellize to both increase and reduce image size?
Absolutely! Pixellize offers tools to both increase and reduce image size in KB. You can maintain exact file sizes for online forms, applications, or social media uploads without compromising quality.
