Frequently Asked Questions
How do I resize an image to 100KB?
Upload the image, enter 100 in “Max file size (KB)”, choose JPG or WebP and click Resize. The tool lowers the quality automatically until the file is under 100KB.
How do I resize a photo in cm or inches?
Select cm, mm or inch from the Unit menu, set the DPI (300 for print) and enter the width and height.
What is the difference between stretch and edge to edge?
Stretch forces the image into the exact size and may distort it. Edge to edge keeps the original proportions, enlarges the image and crops the extra edges.
Is my image uploaded to a server?
No. Everything happens in your browser, so your photos stay private.
