Frequently asked questions
Will resizing reduce the quality?
Making an image smaller keeps it sharp — this tool scales down in steps with high-quality smoothing to avoid jagged edges. Enlarging can't add detail, so big upscales look soft.
What does “Keep aspect ratio” do?
It keeps the width-to-height proportion so the picture isn't squashed. Type a width and the height follows (or the other way round); in a batch each image keeps its own proportions.
What's the difference between Fill & crop, Fit with padding and Stretch?
Fill & crop covers the whole new size and trims the edges that don't fit. Fit with padding shows the whole image and fills the empty space with a colour. Stretch forces the exact size and distorts the image.
What size is a passport photo in pixels?
A 35×45 mm photo (UK, EU, India and many others) is 413×531 px at 300 dpi; a US 2×2 inch photo is 600×600 px. Check your country's rules for head size and background.
Are my photos uploaded?
No. Resizing uses your browser's canvas, so the images stay on your device.
Does it change the DPI?
Image files are measured in pixels; DPI only matters when printing. To print at 300 dpi, multiply the print size in inches by 300 to get the pixels you need.
