Review the preview and dimensions, choose an output format, and download the resized image.

FAQ
How do I resize an image to exact pixel dimensions?
Choose Pixels, enter a width and height between 1 and 16,384 px, then check the preview. Keep aspect ratio is on by default, so the other dimension adjusts automatically. Turn it off if you need to set each dimension separately.
Can I resize an image by percentage or use a social media preset?
Yes. Percentage mode offers 25%, 50%, and 75% options, plus a custom percentage from 1% to 400%. Preset mode includes aspect ratios and named sizes for Instagram, Facebook, X, YouTube, LinkedIn, and Pinterest.
What happens when the target size has a different aspect ratio?
For presets, Fill is selected by default when proportions differ. With Keep aspect ratio turned off, you can choose Fill to crop edges, Fit to add borders, or Stretch to change the image proportions. Fill lets you choose which area remains visible, and Fit lets you choose a border fill.
Which formats can I use, and is my image uploaded?
You can open JPG, PNG, or WebP files and save as JPG, PNG, or WebP. GIF input is not accepted. Processing happens in your browser, and the image file is not uploaded.
Does resizing keep EXIF or GPS metadata, and can I resize several images at once?
No. EXIF, GPS, XMP, and embedded color profiles are not retained, though phone photo orientation is applied to the saved pixels. This tool processes one image at a time.
