Frequently Asked Questions About Our Image Sizer Online
Is this image sizer online tool free to use?
Yes, the tool is free for regular use. You can resize and optimize your images without creating an account.
How many images can I resize at the same time?
You can upload and resize up to 500 JPG or PNG files in a single batch.
Which image formats does this tool support?
The tool accepts JPG and PNG as input. You can export the resized images either as JPG or PNG.
What do Stretch, Crop to Fill and Fill modes mean?
Stretch forces the image to match the exact width and height. Crop to Fill keeps the image proportion and crops extra parts to fill the frame. Fill fits the image inside the target frame, which may leave borders or padding.
Does resizing reduce image quality?
When exporting as JPG, you can choose a quality percentage. Higher quality keeps more details but increases file size. PNG is lossless but may result in larger files.
Can I convert my pictures to black and white?
Yes. Enable the Black & White effect to convert all images in the batch into grayscale during processing.
Is it possible to rotate images while resizing?
Definitely. Add a rotation value in degrees (like 90, 180 or 270) to rotate all selected images while they are being resized.
