Frequently Asked Questions
Everything you need to know about this tool and how it works.
See Full FAQMany portals reject photos above a size limit (for example 20KB, 50KB, or 100KB). This tool shrinks your image until it fits under the limit you set.
Very small limits need more compression. The tool keeps the highest quality that still fits. For passport-style photos, start with a clear, cropped image for better results.
No. Compression runs fully in your browser. Your image stays on your device.
Output is JPEG, which is what most form portals expect for photos.
If even heavy compression cannot get under the limit, you will see the smallest size achieved. Try cropping, reducing dimensions, or choosing a slightly higher KB limit if the portal allows it.
