Frequently Asked Questions (FAQ)
Does resizing an image affect its quality?
Downscaling usually maintains high clarity, but upscaling (enlarging) an image beyond its original bounds will result in pixelation.
Is my photo uploaded to your server?
No. All image resizing is done completely in your local browser using JavaScript. We never see or store your files.
When should I unlock the aspect ratio?
Unlocking the aspect ratio is useful when you need to fit an image into a specific fixed-size container where exact dimensions matter more than proportions.
What is the maximum file size I can resize?
Because processing is local, there is practically no limit. You can resize images up to 50MB+ without any upload delays.
Can I resize an image for Instagram?
Yes, you can easily enter Instagram's standard square (1080x1080) or portrait (1080x1350) dimensions to prep your photos.
