Frequently Asked Questions
Everything you need to know about this tool.
Many online portals (visa applications, job applications, university portals) have strict file size limits, often 100KB or 200KB for uploaded photos.
It depends on the original dimensions. A small photo (e.g. 400×500px) will look great at 100KB. A very large photo may show some compression artifacts.
JPG, PNG and WebP are supported. JPG typically achieves the smallest file sizes and is recommended for photos.
