Questions people ask
How do I resize a photo to under 50 KB?
Choose your photo, pick a preset or size, and set File size to “Under 50 KB”. The tool lowers the JPG quality step by step until the file fits, and only reduces the dimensions if quality alone is not enough.
What size is a passport-size photo in pixels?
35 × 45 mm at 300 dpi is 413 × 531 pixels. The preset crops your photo from the centre to that shape and saves it with 300 dpi, so it also prints at 35 × 45 mm. Always check the exact size and file limit your form asks for.
Will my photo be stretched?
No. Presets and unlocked width and height crop the photo from the centre to the new shape instead of stretching it. Keep your face in the middle of the original photo for the best result.
Is my photo uploaded anywhere?
No. Resizing happens in your browser on your own device. Nothing is uploaded, which is why it also works on slow mobile data.
What is dpi, and does it matter for online forms?
Dpi only tells a printer how large to print the image. Online forms check pixels and file size (KB), not dpi. A 413 × 531 px photo is the same file whether it says 72 or 300 dpi.
