Frequently Asked Questions
How do I resize an image to an exact width and height?
Enter both a width and a height, then choose a resize mode. Crop to fill trims the edges that do not fit, Add padding places the whole image on a canvas in your padding colour, and Stretch changes the proportions. Keep aspect ratio fits the image inside the box instead, so one side can come out smaller.
How do I resize an image by percentage?
Leave Width and Height empty and enter a percentage, such as 50 for half the width and height. Percentage scaling always keeps the aspect ratio. Values above 100 enlarge the image, so set Allow enlarging to Yes first; enlarging adds pixels but cannot add detail, so photos can look soft.
Can I resize an image to a specific file size in KB?
This tool changes dimensions, not the file size. Smaller dimensions and a lower JPG or WebP quality usually make the file smaller, but no size is guaranteed. For a limit such as 50 KB, use Batch Image Compressor, which lowers JPG or WebP quality until each image fits your target, or tells you when it cannot.
Which formats can I resize, and what happens to animated images?
Upload JPG, JPEG, PNG, WebP, GIF, TIFF or AVIF. Same as original saves the format named by the file extension; you can also choose JPG, PNG or WebP. Animated GIF and WebP files and multi-page TIFFs are resized from their first frame or page only. To resize every frame of a GIF, use Animated GIF Resizer. Camera and location metadata is not copied to the resized image.
What is the upload limit?
The default limit is 30 MiB for one file. Check the upload area for the current limit. The server upload ceiling is 100 MiB per file; file complexity and processing time can also limit conversion. Images can be up to 100 megapixels, and the resized image up to 16,384 px per side and 100 megapixels.
Where are files processed and when are they removed?
This tool uploads files to Zutilium's server for processing. After a successful conversion, uploads are scheduled for deletion after about one minute and generated downloads after about ten minutes. Cleanup runs periodically, so removal is not immediate. Save your result promptly.
