Photo Size Converter — What It Does
A photo size converter (also called a photo dimension changer, image size converter, or picture size changer) lets you change two things about your photo:
- File Size (KB/MB): Compress or expand the file weight to meet portal upload limits.
- Pixel Dimensions (Width × Height): Change the physical canvas size to exact pixel or cm values.

Photo Size vs Photo Dimensions — Quick Guide
📦 File Size (KB/MB)
The amount of storage space the file takes. Controlled by compression quality and resolution. Small file = faster upload, but potentially lower quality.
📏 Dimensions (Pixels)
The width and height in pixels. Determines how large the image appears. A 3000×4000 photo from a phone camera is typically way too large for web forms.
Frequently Asked Questions
What is a photo size converter?→
A photo size converter is a tool that changes the file size (KB/MB), pixel dimensions (width × height), or both of a photograph. It's used when you need to meet specific requirements for online forms, social media, printing, or email attachments.
How do I convert photo dimensions?→
Upload your photo, switch to "Width × Height" mode, enter your desired dimensions in pixels, and click resize. The tool will convert your photo to the exact dimensions you specify while maintaining quality.
Can I convert both dimensions and file size at once?→
Yes! You can first set your desired pixel dimensions, then use the Target KB mode to compress the resized image to a specific file size. This two-step process ensures both dimension and KB requirements are met.
What's the difference between photo size and photo dimensions?→
Photo "size" usually refers to file size (measured in KB or MB), while "dimensions" refers to pixel width and height. Both are important for form uploads — portals often specify both requirements.
