FAQ

How many images can I resize at once?

You can upload and resize up to 50 images in a single batch. Each image can be up to 10MB in size.

What image formats are supported?

We support JPG, PNG, WebP, GIF, BMP, and TIFF input formats. All images are output as optimized JPEG files.

Will my images be stored on your servers?

No, your images are processed temporarily and then deleted. We don't store or share your images.

What's the difference between maintaining aspect ratio and exact dimensions?

Maintaining aspect ratio keeps the original proportions of your images, preventing distortion. Exact dimensions will stretch or crop images to fit the specified width and height exactly.

How long does processing take?

Most batches of 10-20 images process in under 30 seconds. Larger batches may take 1-2 minutes depending on image sizes and dimensions.

Is there a file size limit?

Each individual image can be up to 10MB. There's no limit on the total batch size, but processing time increases with larger files.

Can I resize images to different dimensions?

All images in a batch will be resized to the same dimensions you specify. For different sizes, process them in separate batches.

What quality settings should I use?

For web use, 80-90% quality provides excellent results with good file sizes. For print or archival purposes, use 95-100% quality.
