Details and tips
How it works
Maximum-dimensions mode scales each image to fit within the chosen width and height while preserving its aspect ratio. There is no cropping or padding. Small images stay unchanged unless enlarging is enabled. Percentage mode calculates each output from that image’s original dimensions.
Made for everyday images
Standardize large groups of product photos, prepare smaller email attachments or scale exported design assets.
Frequently asked questions
Can I upload a ZIP of images?
Yes. Standard unencrypted ZIP files can contain JPG, PNG and WebP images in subfolders. Other files, hidden files and nested archives are skipped. RAR, 7z, ZIP64 and split archives are not supported. Files stay on your device.
What are the batch limits?
Up to 100 images and 250 MB of images after extraction per batch. Each ZIP is limited to 250 MB and 1,000 entries. Each input and output image must fit within 8,192 pixels per side and 16 megapixels; completed results are capped at 250 MB.
What happens if a file fails or names repeat?
Each image has its own status. Failures do not stop the remaining images. Download completed files individually or in a ZIP; output folders are flattened and duplicate names receive a numeric suffix. Cancel keeps completed results.
Will every image have identical dimensions?
Not necessarily. Aspect ratios are preserved, so each image fits within the bounds without stretching.
Can I enlarge images?
Enable enlarging in maximum-dimensions mode, or use a percentage above 100%. Enlarging cannot recover missing detail and each output must stay within image limits.
