Frequently asked questions

How do I resize an image?
Choose the picture, enter the new width or height in pixels, percent, centimetres or inches, and press Resize. Keep “Keep proportions” ticked so the picture is not stretched.
Is it free?
Yes, free with no watermark.
Will the quality drop?
Making pictures smaller keeps them sharp. Making them much bigger cannot add detail, so very large enlargements may look soft.
Can I resize many photos at once?
Yes – add them all and they are resized with the same settings and saved together in a ZIP.
I need a size in KB, not pixels
Use Resize Image to KB, which reaches an exact file size such as 50 KB.
Are my photos uploaded?
No. Resizing happens on your device.
